Question

In a C#.net 2010 application I would like a suggestion on how to complete the following task: In a string field I need to make certain the only values that are returned by a routine are: 1. alphabetic characters only 2. The result must be in uppper case 3. No other characters are allowed. Can you tell me how to accomplish this task?

The ^ indicates the start of the string and the $ indicates the end. So the regular expression is looking for a string which contains at least one (the + symbol) upper case letter and nothing else.

You could validate the field with this regular expression: string regExp = ^[A-Z]+$;
