Question

I have the following method delared by Gl:

public static void Get(int pname, out int @params)

I’m trying to get it using reflection in the following way:

MethodInfo mGetMethod = typeof(Gl).GetMethod("Get",
                                             BindingFlags.Public|BindingFlags.Static,
                                             null, 
                                             new Type[] 
                                             { 
                                                 typeof(Int32), 
                                                 typeof(Int32) 
                                             }, 
                                             null);

But I have no success. Why?

Is it because the out keyword?

Use typeof(Int32).MakeByRefType() for your second parameter. I.e.:

MethodInfo mGetMethod = typeof(Gl).GetMethod("Get", bindingFlags.Public|BindingFlags.Static, null, new Type[] { typeof(Int32), typeof(Int32).MakeByRefType() }, null);
