Is it possible in C# to overload a generic cast operator in the following way?

Question!

Just wondering if there is anyway to represent the following code in C# 3.5:

public struct Foo<T> {

    public Foo(T item) {
        this.Item = item;
    }

    public T Item { get; set; }

    public static explicit operator Foo<U> ( Foo<T> a )
        where U : T {

        return new Foo<U>((U)a.Item)
    }
}

Thanks

I think the short answer is "Not possible. Try using a method instead"

Your code boils down to the line: return new Foo
