在 C# 中修改 .resx 文件

Question

我有一个包含名称-值对（两个字符串）的 .resx 文件。 现在我想使用 C# 以编程方式修改某些名称/值对中的值。 我怎样才能做到这一点？

Answer 1

有一个用于资源管理的完整命名空间：System.Resources。 查看 ResourceManager 类以及 ResXResourceReader 和 ResXResourceWriter。

我设法掌握了一种非常古老的调试方法，当我测试一些与资源相关的东西时，我曾经使用过该方法。 这应该对你有用。

public static void UpdateResourceFile(Hashtable data, String path)
    {
        Hashtable resourceEntries = new Hashtable();

        //Get existing resources
        ResXResourceReader reader = new ResXResourceReader(path);
        if (reader != null)
        {
            IDictionaryEnumerator id = reader.GetEnumerator();
            foreach (DictionaryEntry d in reader)
            {
                if (d.Value == null)
                    resourceEntries.Add(d.Key.ToString(), "");
                else
                    resourceEntries.Add(d.Key.ToString(), d.Value.ToString());
            }
            reader.Close();
        }

        //Modify resources here...
        foreach (String key in data.Keys)
        {
            if (!resourceEntries.ContainsKey(key))
            {

                String value = data[key].ToString();
                if (value == null) value = "";

                resourceEntries.Add(key, value);
            }
        }

        //Write the combined resource file
            ResXResourceWriter resourceWriter = new ResXResourceWriter(path);

            foreach (String key in resourceEntries.Keys)
            {
                resourceWriter.AddResource(key, resourceEntries[key]);
            }
            resourceWriter.Generate();
            resourceWriter.Close();

    }

Answer 2

public static void AddOrUpdateResource(string key, string value)
{
    var resx = new List<DictionaryEntry>();
    using (var reader = new ResXResourceReader(resourceFilepath))
    {
        resx = reader.Cast<DictionaryEntry>().ToList();
        var existingResource = resx.Where(r => r.Key.ToString() == key).FirstOrDefault();
        if (existingResource.Key == null && existingResource.Value == null) // NEW!
        {
            resx.Add(new DictionaryEntry() { Key = key, Value = value });
        }
        else // MODIFIED RESOURCE!
        {
            var modifiedResx = new DictionaryEntry() { Key = existingResource.Key, Value = value };
            resx.Remove(existingResource);  // REMOVING RESOURCE!
            resx.Add(modifiedResx);  // AND THEN ADDING RESOURCE!
        }
    }
    using (var writer = new ResXResourceWriter(ResxPathEn))
    {
        resx.ForEach(r =>
        {
            // Again Adding all resource to generate with final items
            writer.AddResource(r.Key.ToString(), r.Value.ToString());
        });
        writer.Generate();
    }
}

Answer 3

如果你想保留资源文件中现有的注释，那么使用这个（基于SirMoreno的代码修改）

 public static void UpdateResourceFile(Hashtable data, String path)
    {
        Hashtable resourceEntries = new Hashtable();

        //Get existing resources
        ResXResourceReader reader = new ResXResourceReader(path);
        reader.UseResXDataNodes = true;
        ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
        System.ComponentModel.Design.ITypeResolutionService typeres = null;
        if (reader != null)
        {
            IDictionaryEnumerator id = reader.GetEnumerator();
            foreach (DictionaryEntry d in reader)
            {
                //Read from file:
                string val = "";
                if (d.Value == null)
                    resourceEntries.Add(d.Key.ToString(), "");
                else
                {
                    val = ((ResXDataNode)d.Value).GetValue(typeres).ToString();
                    resourceEntries.Add(d.Key.ToString(), val);

                }

                //Write (with read to keep xml file order)
                ResXDataNode dataNode = (ResXDataNode)d.Value;

                //resourceWriter.AddResource(d.Key.ToString(), val);
                resourceWriter.AddResource(dataNode);

            }
            reader.Close();
        }

        //Add new data (at the end of the file):
        Hashtable newRes = new Hashtable();
        foreach (String key in data.Keys)
        {
            if (!resourceEntries.ContainsKey(key))
            {

                String value = data[key].ToString();
                if (value == null) value = "";

                resourceWriter.AddResource(key, value);
            }
        }

        //Write to file
        resourceWriter.Generate();
        resourceWriter.Close();

    }

Answer 4

Womp 做对了 (10x)。

但这里有一段代码保持 XML 文件顺序，在文件末尾添加新内容。
（用于源代码控制）

    //Need dll System.Windows.Forms
    public static void UpdateResourceFile(Hashtable data, String path)
    {
        Hashtable resourceEntries = new Hashtable();

        //Get existing resources
        ResXResourceReader reader = new ResXResourceReader(path);
        ResXResourceWriter resourceWriter = new ResXResourceWriter(path);

        if (reader != null)
        {
            IDictionaryEnumerator id = reader.GetEnumerator();
            foreach (DictionaryEntry d in reader)
            {
                //Read from file:
                string val = "";
                if (d.Value == null)
                    resourceEntries.Add(d.Key.ToString(), "");
                else
                {
                    resourceEntries.Add(d.Key.ToString(), d.Value.ToString());
                    val = d.Value.ToString();
                }

                //Write (with read to keep xml file order)
                resourceWriter.AddResource(d.Key.ToString(), val);

            }
            reader.Close();
        }

        //Add new data (at the end of the file):
        Hashtable newRes = new Hashtable();
        foreach (String key in data.Keys)
        {
            if (!resourceEntries.ContainsKey(key))
            {

                String value = data[key].ToString();
                if (value == null) value = "";

                resourceWriter.AddResource(key, value);
            }
        }

        //Write to file
        resourceWriter.Generate();
        resourceWriter.Close();

    }

Answer 5

这是改进的 Womp 的答案 - 没有过时的哈希表，检查文件是否存在并使用 LINQ：

    public static void UpdateResourceFile(Dictionary<string, string> data, string path)
    {
        Dictionary<string, string> resourceEntries = new Dictionary<string, string>();
        if (File.Exists(path))
        {
            //Get existing resources
            ResXResourceReader reader = new ResXResourceReader(path);
            resourceEntries = reader.Cast<DictionaryEntry>().ToDictionary(d => d.Key.ToString(), d => d.Value?.ToString() ?? "");
            reader.Close();
        }

        //Modify resources here...
        foreach (KeyValuePair<string, string> entry in data)
        {
            if (!resourceEntries.ContainsKey(entry.Key))
            {
                if (!resourceEntries.ContainsValue(entry.Value))
                {
                    resourceEntries.Add(entry.Key, entry.Value);
                }
            }
        }

        string directoryPath = Path.GetDirectoryName(path);
        if (!string.IsNullOrEmpty(directoryPath))
        {
            Directory.CreateDirectory(directoryPath);
        }

        //Write the combined resource file
        ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
        foreach (KeyValuePair<string, string> entry in resourceEntries)
        {
            resourceWriter.AddResource(entry.Key, resourceEntries[entry.Key]);
        }
        resourceWriter.Generate();
        resourceWriter.Close();
    }

Answer 6

所有其他答案都使用 ResXResourceWriter，但对于某些特殊情况，简单地将 Resources.resx 文件作为 XML 文档使用可能是可行且更好的。

我有一个特定的情况，我想要操作一组图标文件的 Resources.resx 条目。 可能有多达数百个条目，我可以指望它们看起来都像这样：

  <data name="Incors_workplace2_16x16" type="System.Resources.ResXFileRef, System.Windows.Forms">
    <value>..\..\..\..\..\..\Icons\Incors-workplace2-16x16.png;System.Drawing.Bitmap, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a</value>
  </data>

我尝试在该程序中使用 ResXResourceWriter 和 ResXResourceReader，但最终我将各种 Resources.resx 文件作为 XML 文档打开，并在那样。 整个程序太大了（而且太特定于应用程序），无法在这里发布，但我将发布一些代码来展示一些可以使用的技术。

      /// <summary>
      /// Method to load a Resources.resx file (if it exists) as an XML Document object.
      /// </summary>
      private static XmlDocument LoadResourcesResx(string projectPath)
      {
         string fileName = projectPath + @"Properties\Resources.resx";
         if (!File.Exists(fileName))
            return null;

         XmlDocument xdResx = new XmlDocument();
         xdResx.Load(fileName);
         return xdResx;
      }

         // Loop for all of the <data> elements that have name= attributes (node = "name" attr.)
         XmlNodeList xnlDataElements = xdResx.SelectNodes("/root/data/@name");
         if (xnlDataElements != null)
         {
            foreach (XmlNode xmlNode in xnlDataElements)

Answer 8

这是我基于 Ers 和 SirMoreno 代码的版本。 只是短了一点。 这仍然不是处理元数据，这对我来说是可能的但不是必需的。

    public static bool AddToResourceFile(string key, string value, string comment, string path)
    {
        using (ResXResourceWriter resourceWriter = new ResXResourceWriter(path))
        {
            //Get existing resources
            using (ResXResourceReader reader = new ResXResourceReader(path) { UseResXDataNodes = true })
            {
                foreach (DictionaryEntry resEntry in reader)
                {
                    ResXDataNode node = resEntry.Value as ResXDataNode;
                    if (node == null) continue;

                    if (string.CompareOrdinal(key, node.Name) == 0)
                    {
                        // Keep resources untouched. Alternativly modify this resource.
                        return false;
                    }

                    resourceWriter.AddResource(node);
                }
            }

            //Add new data (at the end of the file):
            resourceWriter.AddResource(new ResXDataNode(key, value) { Comment = comment });

            //Write to file
            resourceWriter.Generate();
        }
        return true;
    }
