列出 C# DLL 中的类和函数头

Question

我有一个第三方 C# DLL（经过混淆处理），我想使用 pythonnet 将它包装在 python 中。

到目前为止，我可以通过在 Visual Studio 2017 中检查 DLL 内容并逐个函数手动编写包装函数来做我想做的事，而且有数百个。我看不到在文本文件中列出或将我在 VS dll 资源管理器中看到的内容复制到文本文件以自动化包装任务的方法。

有没有办法将 .NET (C#) DLL 文件的内容列成文本？

你可以试试这个。

使用反射和 CodeDom，此实现尝试为给定程序集中的所有类型、它们的属性和它们的方法生成空主体源代码。

只需传递PrintOutAssembly 对混淆库程序集的引用即可。

希望这会有所帮助。

private static void PrintOutMethod(CodeTypeDeclaration codeTypeDeclaration, MethodInfo method)
{
    if (method.Name.StartsWith("get_") || method.Name.StartsWith("set_"))
    {
        return;
    }

    CodeMemberMethod codeMethod;

    codeTypeDeclaration.Members.Add
    (
        codeMethod = new CodeMemberMethod()
        {
            Name = method.Name,
            ReturnType = new CodeTypeReference(method.ReturnType),
            Attributes =
                (MemberAttributes.Public) |
                (method.IsFinal ? MemberAttributes.Final : MemberAttributes.Public) |
                (method.IsAbstract ? MemberAttributes.Abstract : MemberAttributes.Public) |
                (method.GetBaseDefinition() != null ? MemberAttributes.Override : MemberAttributes.Public)
        }
    );

    foreach (ParameterInfo parameter in method.GetParameters())
    {
        codeMethod.Parameters.Add
        (
            new CodeParameterDeclarationExpression()
            {
                Name = parameter.Name,
                Direction = parameter.IsIn && parameter.IsOut ? FieldDirection.Ref : parameter.IsOut ? FieldDirection.Out : FieldDirection.In,
                Type = new CodeTypeReference(parameter.ParameterType)
            }
        );
    }
}

{
    codeTypeDeclaration.Members.Add
    (
        new CodeMemberProperty()
        {
            Name = property.Name,
            Type = new CodeTypeReference(property.PropertyType),
