Use string.Contains() with switch()

Question

I\'m doing an C# app where I use

if ((message.Contains(\"test\")))
{
   Console.WriteLine(\"yes\");
} else if ((message.Contains(\"test2\"))) {
   Console.W

This will work in C# 7. As of this writing, it has yet to be released. But if I understand this correctly, this code will work.

switch(message)
{
    case Contains("test"):
        Console.WriteLine("yes");
        break;
    case Contains("test2"):
        Console.WriteLine("yes for test2");
        break;
    default:
        Console.WriteLine("No matches found!");
}
