GetOriginalTypeParameterType throws Object reference not set to an instance of an object exception

Question

Reference: How can a dynamic be used as a generic?

public void CheckEntity(int entityId, string entityType = null)
{
 dynamic AnyObject = Activator.CreateIns         


        

Answer 1

As discussed in C# chat room, the solution here is to bypass dynamic entirely and use reflection to invoke the generic method. Dynamic has some nice features but sometimes causes more trouble than it's worth, especially when it's possible to get the Type object at runtime.

var modelType = Type.GetType("InferenceExample.Models." + entityType + ",InferenceExample");

var checkMethod = typeof(HomeController).GetMethod("CheckWithInference", BindingFlags.NonPublic | BindingFlags.Static);
checkMethod.MakeGenericMethod(modelType).Invoke(null, new object[] { entityId });

Glad to help :)
