Is it possible to code a Regex.IsMatch that returns True if it finds exact matches of multiple values, simulating a Case Statement?  Pseudo code:

// Select Case MyString
// Case MyValue1,MyValue2,MyValue3
if (Regex.IsMatch(MyString,"MyValue1,MyValue2,MyValue3") {
    Console.WriteLine("MyString equals MyValue1 or MyValue2 or MyValue3");
}
// Case Else
else {
    Console.WriteLine("MyString doesn't equal MyValue1 or MyValue2 or MyValue3");
}
// End Select

I'm getting compile errors on the ^ and $ characters:

if (!Regex.IsMatch(MyString,^("val1"|"val2"|"val3")$)
