Bear with me, I have been out of the .Net loop for awhile. I have a need to use a regular expression and I could use some help crafting it. The expression needs to search an input string for a substring in the following format: #AA### where # is a number and A is a letter. The string will always be 6 characters long. The matching string should be returned, and this data will be added to a database.

Does anyone have an example of how this might be written?

Thanks!

You can use the following expression: ^\d{1}[A]{2}\d{3}$

You can use it like this C# code sample:

Code:

if (Regex.IsMatch(YourInputString, "^\\d{1}[A]{2}\\d{3}$"))
    Response.Write("pass");
else
    Response.Write("fail");
