.NET XmlSerializer:如何替换 xml 标签的名称?

对于某些数据导出,我们所做的只是使用 XmlSerializer 序列化 .Net 对象,例如列表或集合。我们使用这样的东西:

public static bool WriteToXMLFile(string fullFileNameWithPath, Object obj, Type ObjectType)
        {
            TextWriter xr = null;
            try
            {
                XmlSerializer ser = new XmlSerializer(ObjectType);
                xr = new StreamWriter(fullFileNameWithPath);
                ser.Serialize(xr, obj);
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                if(xr != null)
                    xr.Close();
            }
            return true;
        }

对于类型的列表,生成的 XML 类似于以下片段:

<ArrayOfMyObjects>
    <MyObject>
    //content here
    </MyObject>
</ArrayOfMyObjects>

但另一边的期望(该文件的接收者是这样的:

<MT_MyObjects>
    <MyObject>
    //content here
    </MyObject>
</MT_MyObjects>

那么我如何将 ArrayOfMyObjects 更改为 MT_MyObjects,同时序列化?我知道也可以使用一些 Regx 替换来完成,但我不想稍后再修改

输出:

我最终可以这样解决问题:

[Serializable]
[XmlRoot("MT_LoadProfile")]
public class LoadProfArray : List<LoadProfile>
{
    //....
}

For some data export, what we are doing is just serializing the .Net objects like a list or Collection using XmlSerializer. We use something like this:

public static bool WriteToXMLFile(string fullFileNameWithPath, Object obj, Type ObjectType)
        {
            TextWriter xr = null;
            try
            {
                XmlSerializer ser = new XmlSerializer(ObjectType);
                xr = new StreamWriter(fullFileNameWithPath);
                ser.Serialize(xr, obj);
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                if(xr != null)
                    xr.Close();
            }
            return true;
        }

For a list of a type, the XML that is generated comes like the following segment:

<ArrayOfMyObjects>
    <MyObject>
    //content here
    </MyObject>
</ArrayOfMyObjects>

But the expectation on the other side (receiver of this file is something like this:

<MT_MyObjects>
    <MyObject>
    //content here
    </MyObject>
</MT_MyObjects>

So how can I change ArrayOfMyObjects to MT_MyObjects while serializing? I know it can be done using some Regx replacement also. But I wanted not to touch the output later.

Update: The solution:

I could solve the issue finally like this:

[Serializable]
[XmlRoot("MT_LoadProfile")]
public class LoadProfArray : List<LoadProfile>
{
    //....
}

对于序列化数组,您可以定义控制对象序列化方式的属性。但是,如果对象是列表,则需要创建一个类并继承它,然后定义属性:

[XmlRoot("DocumentTypes")]
public class DocumentTypeEntityCollection
{

    [XmlElement("Type")]
    public  List<DocumentTypeEntity> Items { get; set; }
}

这将创建以下输出:

<?xml version="1.0" encoding="utf-8" ?>
<DocumentTypes>
  <Type>
    <TypeID>7</TypeID>
   ....

For serialising Arrays, you can define attributes which governs how an object is serialised. However if the object is a list, you need to create a class and inherit from it and then define the attributes:

[XmlRoot("DocumentTypes")]
public class DocumentTypeEntityCollection
{

    [XmlElement("Type")]
    public  List<DocumentTypeEntity> Items { get; set; }
}

This will create this output:

<?xml version="1.0" encoding="utf-8" ?>
<DocumentTypes>
  <Type>
    <TypeID>7</TypeID>
   ....

在你的班级中,用

[XmlArray("MT_MyObjects"), XmlArrayItem(typeof(MyObject))]

In your class, decorate the property with

[XmlArray("MT_MyObjects"), XmlArrayItem(typeof(MyObject))]

请查找下面的示例:
/步骤1/
其集合要被序列化的虚拟类

[Serializable]
    public class MyObject
    {
        public string ChildObject1 { get; set; }
        public string ChildObject2 { get; set; }
        public MyObject(string childObject1, string childObject2)
        {
            ChildObject1 = childObject1;
            ChildObject2 = childObject2;
        }
        public MyObject()
        {

        }
    }

/Step2/
创建列表集合并应用 XMLRootElement

[XmlRoot("Test")]
    public class MyObjectCollection: List<MyObject>
    {

    }

/步骤 3/

用数据填充 MyObject 类并序列化

MyObjectCollection lst = new MyObjectCollection();
            lst.Add(new MyObject("1", "a"));
            lst.Add(new MyObject("2", "b"));
            lst.Add(new MyObject("3", "c"));
            try
            {
                XMLFileAgent.WriteToXMLFile(@"C:\TestLog.xml", lst, lst.GetType());
            }
            catch (Exception ex)
            {
                throw ex;
            }

Please Find The Example below:
/Step1/
The Dummy Class whose collection was to be serialised

[Serializable]
    public class MyObject
    {
        public string ChildObject1 { get; set; }
        public string ChildObject2 { get; set; }
        public MyObject(string childObject1, string childObject2)
        {
            ChildObject1 = childObject1;
            ChildObject2 = childObject2;
        }
        public MyObject()
        {

        }
    }

/Step2/
Create a List Collection and Apply The XMLRootElement

[XmlRoot("Test")]
    public class MyObjectCollection: List<MyObject>
    {

    }

/Step3/

Populate the MyObject Class with Data and serialise

MyObjectCollection lst = new MyObjectCollection();
            lst.Add(new MyObject("1", "a"));
            lst.Add(new MyObject("2", "b"));
            lst.Add(new MyObject("3", "c"));
            try
            {
                XMLFileAgent.WriteToXMLFile(@"C:\TestLog.xml", lst, lst.GetType());
            }
            catch (Exception ex)
            {
                throw ex;
            }
