How to get id from database that's equal DataGridView1 selected row id cell value in c#?

I have this code in vb.net, and now I have to convert it to c#.

Although it's a duplicate from Getting the first cell from selected row from DataGridView in C#

getting the first cell value from selected row would be:

dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
