How to verify whether a type overloads/supports a certain operator?

Question

How can I check whether a certain type implements a certain operator?

struct CustomOperatorsClass
{
    public int Value { get; private set; }


    public C         


        

Answer 1

There is a quick and dirty way to find out, and it works for both built-in and custom types. Its major drawback is that it relies on exceptions in a normal flow, but it gets the job done.

 static bool HasAdd() {
    var c = Expression.Constant(default(T), typeof(T));
    try {
        Expression.Add(c, c); // Throws an exception if + is not defined
        return true;
    } catch {
        return false;
    }
}
