为给定 System.Type 的类定义生成源代码？

发布于 2025-01-02 04:51:31 字数 374 浏览 1 评论 0原文

.NET 中有没有办法在给定 System.Type 的情况下创建源代码类定义？

public class MyType
{
   public string Name { get; set; }
   public int Age { get; set; }
}


string myTypeSourceCode = GetSourceCode( typeof(MyType) );

基本上我正在寻找 GetSourceCode() 是什么。

我意识到会有限制：如果有属性获取器/设置器或私有成员，则不包含源代码，但我不需要它。假设该类型是数据传输对象，因此只需公开公共属性/字段。

我用它来自动生成 Web API 的代码示例。

原文

Is there a way in .NET to create the source code class definition given a System.Type?

public class MyType
{
   public string Name { get; set; }
   public int Age { get; set; }
}


string myTypeSourceCode = GetSourceCode( typeof(MyType) );

Basically I'm looking for what GetSourceCode() is.

I realize there would be limitations: If there are property getters/setters or private members the source is not included, but I don't need that. Assume the type is a Data Transfer Object, so just the public properties/fields need to be exposed.

What I'm using this for is auto-generated code examples for a web API.

如果您只想生成像您所示的伪接口代码，您可以迭代公共字段和公共字段。像这样的属性：

string GetSourceCode(Type t)
{
    var sb = new StringBuilder();
    sb.AppendFormat("public class {0}\n{{\n", t.Name);

    foreach (var field in t.GetFields())
    {
        sb.AppendFormat("    public {0} {1};\n",
            field.FieldType.Name,
            field.Name);
    }

    foreach (var prop in t.GetProperties())
    {
        sb.AppendFormat("    public {0} {1} {{{2}{3}}}\n",
            prop.PropertyType.Name,
            prop.Name,
            prop.CanRead ? " get;" : "",
            prop.CanWrite ? " set; " : " ");
    }

    sb.AppendLine("}");
    return sb.ToString();
}

对于类型：

public class MyType
{
    public int test;
    public string Name { get; set; }
    public int Age { get; set; }
    public int ReadOnly { get { return 1; } }
    public int SetOnly { set {} }
}

输出是：

public class MyType
{
   public Int32 test;
   public String Name { get; set; }
   public Int32 Age { get; set; }
   public Int32 ReadOnly { get; }
   public Int32 SetOnly { set; }
}

If you just want to generate pseudo-interface code like you have shown, you can iterate over the public fields & properties like this:

string GetSourceCode(Type t)
{
    var sb = new StringBuilder();
    sb.AppendFormat("public class {0}\n{{\n", t.Name);

    foreach (var field in t.GetFields())
    {
        sb.AppendFormat("    public {0} {1};\n",
            field.FieldType.Name,
            field.Name);
    }

    foreach (var prop in t.GetProperties())
    {
        sb.AppendFormat("    public {0} {1} {{{2}{3}}}\n",
            prop.PropertyType.Name,
            prop.Name,
            prop.CanRead ? " get;" : "",
            prop.CanWrite ? " set; " : " ");
    }

    sb.AppendLine("}");
    return sb.ToString();
}

For the type:

public class MyType
{
    public int test;
    public string Name { get; set; }
    public int Age { get; set; }
    public int ReadOnly { get { return 1; } }
    public int SetOnly { set {} }
}

The output is:

public class MyType
{
   public Int32 test;
   public String Name { get; set; }
   public Int32 Age { get; set; }
   public Int32 ReadOnly { get; }
   public Int32 SetOnly { set; }
}
