How do you get the type of the generic from a reference?

Question

I have a variable defined as:

Generate<IResource> generation = FindComponent<Generate<IResource>>();

Which finds the first component of this type.

But i need to now get the type of IResource from the variable generation so i know what resource is in use. But i am not sure how to obtain it from the variable. Is this possible?

Without us knowing any of the code of `Generate` no it's impossible — Charlieface, Jan 24 '21 at 07:16
To use the duplicate, just replace `List<>` by `Generate<>`. — , Jan 24 '21 at 07:21

In theory, the following would do, using the Type.GetGenericArguments method:

generation.GetType().GetGenericArguments()[0]);

Check this fiddle

using System;
            

public class Generate<IResource> {
}

public interface IResource {}
public class Resource: IResource {}

public class Program
{
    public static void Main()
    {
        Generate<Resource> generation = new Generate<Resource>();
        Console.WriteLine(generation.GetType().GetGenericArguments()[0]);
    }
}

Output: Resource

Weird i seem to get out of bounds error when accessing [0]. – WDUK Jan 24 '21 at 07:21

Returns an empty array if the current type is not a generic type. – Athanasios Kataras Jan 24 '21 at 07:22
