Error binding to target method

问题

MethodInfo method = typeof(T).GetMethod("Parse", new[] { typeof(string) });
parse = Delegate.CreateDelegate(typeof(Func<T,string>), method);

T is a float in this case. However I am getting a Error binding to target method. Parse I believe is a static method. I have looked at other examples, but I can not figure out why it is not binding.

回答1:

you have to swap T and string because the method returns a T not a string.

I replaced T with float and following code works for me:

MethodInfo method = typeof(float).GetMethod("Parse", BindingFlags.Static | BindingFlags.Public, null, new[] { typeof(string) }, null);

var parse = Delegate.CreateDelegate(typeof(Func<string, float>), method);
