Visual Studio线程语句给出错误？

Question

我反编译.NET应用程序来编写自己的注入软件。线程错误不希望被删除。我尝试了一切，但它一直告诉我有些事情是错的......

我认为你得到The call is ambiguous between the following methods or properties: 'Thread.Thread(ThreadStart)' and 'Thread.Thread(ParameterizedThreadStart)'错误。

正如您所正确指出的那样，编译器无法区分Thread构造函数参数的类型。如果在调用ParameterizedThreadStart方法时将参数传递给代理，则使用Thread.Start。您的代码不会这样做。因此，你需要一个ThreadStart代表。它的语法是

public delegate void ThreadStart();

即它不接受任何参数，也不返回值。所以，你可以通过一个同样的lambda function。

new Thread(() => {
    // ...
}).Start();
