Question

With this code:

World w = new World();
var data = GetData<World>(w);

If I get w with reflection and this can be of type World, Ambient, Domention, etc.

How can I get GetData ???

I only have the instance object:

var data = GetData<???>(w);

Answer 1

var type = <The type where GetData method is defined>;

var genericType = typeof(w);

var methodInfo = type.GetMethod("GetData");

var genericMethodInfo = methodInfo.MakeGenericMethod(genericType);

//instance or null : if the class where GetData is defined is static, you can put null : else you need an instance of this class.
var data = genericMethodInfo.Invoke(<instance or null>, new[]{w});
