c# winform if datagrid cell equals Bob next datagrid cell returns Male

I hope I can explain this simply, I have  a Datagrid with several columns. I want to write, if this column [2] has Bob in it than column [3] returns Male. The Excel formula would look like this =IF (Y2 = "Bob"),"Male",0), where Y2 is column [2] Bob  and column [3] returned Male.

what is this function called?
