I have a generic function that is constrained to struct. My inputs are boxed ("objects"). Is it possible to unbox the value at runtime to avoid having to check for each possible type and do the casts manually?

See the above example:

   public struct MyStruct
    {
        public int Value;
    }

    public void Foo<T>(T test)
        where T : struct
    {
        // do stuff
    }

    public void TestFunc()
    {
        object o = new MyStruct() { Value = 100 }; // o is always a value type

        Foo(o);
    }

In the example, I know that o must be a struct (however, it does not need to be MyStruct ...). Is there a way to call Foo without tons of boilerplate code to check for every possible struct type?

Thank you.
