Generic class instance with type from PropertyInfo.PropertyType


I have classes like below:

public class SampleClassToTest<T>
{
    public static Fake<T> SomeMethod(string parameter)
    {
        // some code
    }

    public static Fake<T> SomeMethod(string parameter, int anotherParameter)
    {
        //some another code
    }
}

public class Fake<T>
{
    // some code
}

And I want to use them in this way:

SampleClassToTest<MyClass>.SomeMethod("some parameter");

The problem which I have is the following: type of "MyClass" I can get only from PropertyInfo instance using Reflection, so I have

Type propertyType = propertyInfo.PropertyType;

How can I do this? Any ideas?

UPD. I'm trying to pass the Type to generic method. And yes, this is what I want.


Solution

  • You would need to do:

    typeof(SampleClassToTest<>).MakeGenericType(propertyType)
           .GetMethod("SomeMethod", new Type[] {typeof(string)})
           .Invoke(null, new object[] {"some parameter"});
    

    Ugly.

    If it can at all be helped, I would advise offering a non-generic API that accepts a Type instance; the nice thing here is that a generic API can call into a non-generic API trivially by using typeof(T).
