Ungreedy regex in C#

I have a string like fcsNotificationZK44_0376300009215000019_4158794.xml and a pattern (fcs.*)_ the target is to get fcsNotificationZK44 but standart C# Regex matched at fcsNotificationZK44_0376300009215000019 becouse it is greedy. In javascript I can use /U modifier to turn on ungreedy mode but how to solve it in C# Regex? Thanks.

You could use a not operator:

(fcs[^_]*)_

Use *? to make the * non-greedy.
