任何方法类型的委托 - C# [英] Delegate for any method type - C#
本文介绍了任何方法类型的委托 - C#的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想要一个可以执行任何外部方法的类，像这样:
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(ParametersForMethod) //or something like that
}
}
这可能吗?是否有接受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
你可以通过 Func
You can do this a different way by Func<T> and closures:
public T Execute<T>(Func<T> method)
{
// stuff
return method();
}
然后调用者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替你做辛苦的工作，方法调用和返回值都是类型安全的，提供智能感知等.
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.
