How can I validate Guid datatype?

Question

Is there a way to validate GUID datatype?

I'm using validation attributes. http://msdn.microsoft.com/en-us/library/ee707335%28v=vs.91%29.aspx

Answer 1

You can use a RegularExpressionAttribute. Here's a sample using the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:

[RegularExpression(Pattern = "[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}")]

You can also create a custom validation attribute, which is probably a cleaner solution.
