C# AsyncStateMachine反编译

Question

我的代码几乎可以正常工作，但是 OnRequest 方法充满了错误，我看到它是我认为的编译代码。是否有助于将此代码变成人类可读的代码？

[AsyncStateMachine(typeof(Service1.<OnRequest>d__24))]
public Task OnRequest(object sender, SessionEventArgs e)
{
    Service1.<OnRequest>d__24 <OnRequest>d__;
    <OnRequest>d__.<>4__this = this;
    <OnRequest>d__.e = e;
    <OnRequest>d__.<>t__builder = AsyncTaskMethodBuilder.Create();
    <OnRequest>d__.<>1__state = -1;
    AsyncTaskMethodBuilder <>t__builder = <OnRequest>d__.<>t__builder;
    <>t__builder.Start<Service1.<OnRequest>d__24>(ref <OnRequest>d__);
    return <OnRequest>d__.<>t__builder.Task;
}

或者我在这里很无助，我不知道那是什么，如果我无法解决这个问题，我希望在最坏的情况下得到解释。

字符<和 >无效 C#对于类型和变量名称，但它们在 CIL 中完全有效代码。

ILSpy 不会“规范化”名称，因此您会得到不可编译的代码，但您可以删除特殊字符来修复它:

[AsyncStateMachine(typeof(Service1.OnRequestd__24))]
public Task OnRequest(object sender, SessionEventArgs e)
{
    Service1.OnRequestd__24 OnRequestd__;
    OnRequestd__.__this = this;
    OnRequestd__.e = e;
    OnRequestd__.t__builder = AsyncTaskMethodBuilder.Create();
    OnRequestd__.__state = -1;
    AsyncTaskMethodBuilder t__builder = OnRequestd__.t__builder;
    t__builder.Start<Service1.OnRequestd__24>(ref OnRequestd__);
    return OnRequestd__.t__builder.Task;
}

如果您还实现了引用类型，则可以完美编译:

public class Service1
{
    public struct OnRequestd__24 : IAsyncStateMachine
    {
        public ObjectPoolAutoTest __this;
        public SessionEventArgs e;
        public AsyncTaskMethodBuilder t__builder;
        public int __state;
        public void MoveNext() => throw new NotImplementedException();

        public void SetStateMachine(IAsyncStateMachine stateMachine) => throw new NotImplementedException();
    }
}
