Generic value equality (identity) in C#

Question

What is the best (most concise and optimal) way to compare two instances of same generic type such that reference types are compared for identity (same object, so not calling Equals) and value types for value equality.

Currently I do this:

static bool IdentityEquals<T>(T x, T y)
{
    return typeof(T).IsValueType
        ? EqualityComparer<T>.Default.Equals(x, y)
        : ReferenceEquals(x, y);
}

Answer 1

You should be able to just use object.Equals for value types:

 return typeof(T).IsValueType
    ? object.Equals(x, y)
    : ReferenceEquals(x, y);
