IsNullOrWhiteSpace with capital S not a "s".

[viveleltsi]

Hello
I think there's a mistake on the RegexUtilities class.
"
if (string.IsNullOrWhitespace(email))
return false;
"
string.IsNullOrWhitespace(email) should be string.IsNullOrWhiteSpace(email) with a capital "S" at space not a "s").

I hope my comment will help.

Best regards

Dan

Thanks for your comment, @viveleltsi. In the C# code, the method call appears as is string.IsNullOrWhiteSpace(email). Whether the type name is capitalized (String) or not (string) is a matter of coding style, since the C# string keyword is an alias for the .NET String class. Either form compiles successfully.
I'll close this issue as By Design.

I was talking of the name of the method not the string class. IsNullOrWhitespace do not work.

I agree with viveleltsi, the example is not working because there is a typo in the method name 'string.IsNullOrWhiteSpace(email)'. It's writtent 'IsNullOrWhitespace', missing the capital 'S' to 'space'.

He is not talking about the class name string.
