What does MethodInvoker mean in C#?

In C#, MethodInvoker is a delegate used to call a method without any parameters and without a return value. It is a generic delegate type that can be used to call any method that fits its signature.

The definition of MethodInvoker is as follows:

public delegate void MethodInvoker();

One way to execute a method is by instantiating a MethodInvoker delegate and passing the method to be called as a parameter, then using the Invoke method to execute it.

For example, if there is a method called MyMethod, it can be invoked using MethodInvoker.

void MyMethod()
{
    // 执行一些操作
}

MethodInvoker methodInvoker = new MethodInvoker(MyMethod);
methodInvoker.Invoke();

In the example above, methodInvoker.Invoke() will call the MyMethod method. Since MyMethod method has no parameters and no return value, MethodInvoker can be used to call it.
