委托任何方法类型 - C＃ [英] Delegate for any method type - C#

问题描述

我想有一个类，将执行任何外部方法，如：

I want to have a class that will execute any external method, like this:

class CrazyClass
{
  //other stuff

  public AnyReturnType Execute(AnyKindOfMethod Method, 
    object[] ParametersForMethod)
  {
    //more stuff
    return Method(Parameters) //or something like that
  }
}

时这可能吗？有没有采取任何方法签名的委托？

Is this possible? Is there a delegate that takes any method signature?

推荐答案

您可以在此通过 Func键和下做不同的方式; T> 和关闭：

You can do this a different way by Func<T> and closures:

public T Execute<T>(Func<T> method)
{
   // stuff
   return method();
}

调用者然后可以使用闭包来实现它：

The caller can then use closures to implement it:

var result = yourClassInstance.Execute(() => SomeMethod(arg1, arg2, arg3));

这里的好处是，你让编译器做艰苦的工作适合你，方法调用和返回值的类型都是安全的，提供智能感知，等等。

The advantage here is that you allow the compiler to do the hard work for you, and the method calls and return value are all type safe, provide intellisense, etc.
