✅ Getting generic type parameters using reflection

Using the reflection system, how can I get at the generic type parameters?
I have the following:

public class MyClass<T1, T2> {}

Type myClassType = typeof(MyClass<string, int>);
Type myClassGenericType = myClassType.GetGenericTypeDefinition();

public class MyClass<T1, T2> {}

Type myClassType = typeof(MyClass<string, int>);
Type myClassGenericType = myClassType.GetGenericTypeDefinition();

public class MyClass<T1, T2> {}

Type myClassType = typeof(MyClass<string, int>);
Type myClassGenericType = myClassType.GetGenericTypeDefinition();

public class MyClass<T1, T2> {}

Type myClassType = typeof(MyClass<string, int>);
Type myClassGenericType = myClassType.GetGenericTypeDefinition();

And from

myClassGenericType

myClassGenericType

myClassGenericType

myClassGenericType, I want to get details of what the generic type parameters are (

T1

T1

T1

T1 and

T2

T2

T2

T2).

In the debugger, this information is in

GenericTypeParameters

GenericTypeParameters

GenericTypeParameters

GenericTypeParameters on

RuntimeType

RuntimeType

RuntimeType

RuntimeType, but this isn't part of

Type

Type

Type

Type, and

RuntimeType

RuntimeType

RuntimeType

RuntimeType is private, so I can't get at its internals.
