用CodeDOM编程生成C#代码文档(摘要)

我想用CodeDOM生成C#代码文档。

无文档代码：

public class MyType {                 
    public static BitmapImage File {
        get { return GetFile("..."); }
    }
}

带文档的代码：

/// <summary> Gets the File from the location </summary>
public class MyType {                 
    public static BitmapImage File {
        get { return GetFile("..."); }
    }
}

或

/// <summary>
/// Gets the File from the location 
/// </summary>
/// <param name="path"></param>
/// <returns></returns>
public class MyType {                 
    public static BitmapImage File {
        get { return GetFile("..."); }
    }
}

我可以生成Class，Member，我可以添加一些属性和装饰器，但如何生成文档-不幸的是没有。

我如何生成成员：

private CodeTypeDeclaration CreateType() {
    var classType = new CodeTypeDeclaration("MyType") {
        Attributes = MemberAttributes.Public | MemberAttributes.Static
    };
    var properties = CreateMembers();
    classType.Members.AddRange(properties);
    return classType;
}
private CodeTypeMember[] CreateMembers() {
    var members = _members.Where(x => IsMy(x.Name));
    var props = members.Select(CreateProperty).ToArray();
    return props;
}
private CodeTypeMember CreateProperty(X x) {
    var name = Path.GetFileNameWithoutExtension(x.Name);     
    var property = new CodeMemberProperty {
        Name = name,
        HasGet = true,
        Attributes = MemberAttributes.Public | MemberAttributes.Static,
        Type = new CodeTypeReference(typeof(BitmapImage)),
    };
    var targetObject = new CodeTypeReferenceExpression(typeof(Y));
    var method = Return(new CodeMethodInvokeExpression(targetObject, "Getx", Primitive(x.Name)));
    property.GetStatements.Add(method);
    return property;
}
private bool IsMy(string path) {
    var extension = Path.GetExtension(path.ToLower());
    var isMy = Regex.IsMatch(extension, @"'.(jpg)$");
    return isMy;
}

添加实现：

private CodeTypeMember CreateProperty(X x) {
    var name = Path.GetFileNameWithoutExtension(x.Name);     
    var property = new CodeMemberProperty {
        Name = name,
        HasGet = true,
        Attributes = MemberAttributes.Public | MemberAttributes.Static,
        Type = new CodeTypeReference(typeof(BitmapImage)),
    };
    var targetObject = new CodeTypeReferenceExpression(typeof(Y));
    var method = Return(new CodeMethodInvokeExpression(targetObject, "Getx", Primitive(x.Name)));
    property.GetStatements.Add(method);
   //because CodeMemberProperty.Comments is readonly I cast it to CodeTypeMember, which has read/write Comments
    var docStart = new CodeCommentStatement("<summary>", true);
    var fileSystemName = string.Format("File system Name: {0}", x.Name);
    var docContent = new CodeCommentStatement(fileSystemName, true);
    var docEnd = new CodeCommentStatement("</summary>", true);
    var result = property as CodeTypeMember;
    result.Comments.AddRange(new CodeCommentStatementCollection {
        docStart,
        docContent,
        docEnd
    });
    return result;
}

CodeTypeDeclaration class1 = new CodeTypeDeclaration("Class1");
class1.Comments.Add(new CodeCommentStatement("<summary>", true));
class1.Comments.Add(new CodeCommentStatement("Create a Hello World application.", true));
class1.Comments.Add(new CodeCommentStatement("</summary>", true));
