Regular Expressions in .NET (C#)
-
Can anyone help me? I`ve just started my adventure with .NET. I want use regular expression in my text box to validate text. For example reg. expression like this : "[0-9][0-9]-[0-9][0-9][0-9]" accepts only for example "43-456" text. What if I enter "54-8f5" ? .NET Regular Expressions tells me that this text is not correct. But it doesn`t tell me which character is invalid. My problem is that I want .NET Regular Expressions show me which character (which character index in this incorrect string) is invalid. Can anyone help with this? conrados
