C# 2010 eidt

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]+$";
