Is there any way through which we can update List records based on specified condition in C#, any customized method will also work except loop -

lststudents.first(m => m.passed == "").passoutyear= currentyear; 

is there other way update records in bulk above statement updates on first record in list.

foreach (var student in lststudents.where(m => m.passed == "")) {     student.passoutyear = currentyear; }
