How do I assign a static method to a delegate in C# via reflection

Question

Consider the following code:

internal delegate object FactoryMethod();

Now say I have the following code:

String myStaticMethod = "FooFactory.GetInstance()";

How do I do the following?

FactoryMethod myMethod = //A delegate pointing to FooFactory.GetInstance()

I'm googling away, but I can't seem to find a clean example or at least one that deals with static methods.

Answer 1

Use one of overloads of the Delegate.CreateDelegate . Here is one possible way:

var className = "FooFactory";
var methodName = "GetInstance";
var implType = Type.GetType(className);
var implMethod = implType.GetMethod(methodName, new Type[0]);
var res = Delegate.CreateDelegate(typeof(FactoryMethod), implMethod);

Answer 2

我发现了这一点：

typeof(YourClass).GetMethod("GetInstance", BindingFlags.Public | BindingFlags.Static);
