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<T>() {
    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;
    }
}

Answer 2

An extension method called HasAdditionOp like this:

pubilc static bool HasAdditionOp(this Type t)
{
    var op_add = t.GetMethod("op_Addition");
    return op_add != null && op_add.IsSpecialName;  
} 

Note that IsSpecialName prevents a normal method with the name "op_Addition";

Answer 3

You should check if class have method with op_Addition name You can find overloaded method names here,
Hope this helps
