Another of my fairly simple functions (actually written by a colleague of mine, Jonny Anderson) - this time just a simple way to validate a Guid - in this implementation you pass in a Guid as an 'out' parameter along with the string you want to test - it then fills in the Guid and returns true / false depending on whether the Guid was valid...
private static Regex isGuid = new Regex(@"^(\{){0,1}[0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12}(\}){0,1}$", RegexOptions.Compiled);
internal static bool IsGuid(string candidate, out Guid output)
{
bool isValid = false;
output=Guid.Empty;
if(candidate!=null)
{
if (isGuid.IsMatch(candidate))
{
output=new Guid(candidate);
isValid = true;
}
}
return isValid;
}
