c# exclude regex pattern

Question

I am parsing several text files looking for date fields. I want to find this pattern - Date: mm/dd/yyyy but want to exlude this pattern - Cheque Date: mm/dd/yyyy. I have this working for finding the first pattern but it also finds the second pattern as well -

string pattern = @"Date:\s*(.+?)\r";

Using this pattern I can find all combination of dates and not just mm/dd/yyyy.

Use an anchor: @"^Date:\s*(.+?)\r"; binds it to the beginning of the string. — Jan

Is the entire line "Date: mm/dd/yyyy" or "Cheque Date: mm/dd/yyyy", or could there be other characters before those patterns? — Andrew Morton

In addition to my comment, you may want to use an anchor:

string pattern = @"^Date:\s*(.+?)\r";
