Calling method with generic type using class name as string

Question

Having this class :

class ClassA{
}

and a method with this signature:

void MyMethod<T>();

All we use it on this way:

MyMethod<ClassA>();

But... exist some chance of call MyMethod having the class name as string?. I.e.:

var className = "ClassA";

MagicMethod($"MyMethod<{className}>();");

Im talking about some equivalent of Eval in JavaScript. Reflection?, Any idea?

I googled some libraries like DynamicExpresso but nothing with support for generic types.

About possible duplicates:

• Calling a function from a string in C# not solve my problem, my question is specific to call methods with generics types.

Answer 1

Providing you have the following method:

public class Foo
{
     public void MyMethod<T>();
}

You may get the MethodInfo:

MethodInfo methodInfo = typeof(Foo).GetMethod("MyMethod");

Now, let's say you have this class:

public class exampleB
{
}

You can invoke the generic method using the generic parameter type's name:

string genericTypeName = "exampleB";
Type genericType = Type.GetType(genericTypeName);
MethodInfo methodInfo = typeof(Foo).GetMethod("MyMethod").MakeGenericMethod(genericType);

// You will need an instance of Foo to invoke it (the method isn't static)
methodInfo.Invoke(fooInstance, null);

Of course, this will require the run-time to search for type B, so you should be careful and specify the correct namespace too.
