Question: How Can we add ws.Cells["AA"].Value = "MyColumn"; as a column name to Excel worksheet

Following works until column Z1 . But I have more columns after Z column. So, if I add ws.Cells["AA"].Value = "MyColumn"; , following does not work.:

ws.Cells["A1"].Value = "Number";
ws.Cells["B1"].Value = "First Name";
ws.Cells["C1"].Value = "Last Name";
ws.Cells["D1"].Value = "Country";
....
....
ws.Cells["Z1"].Value = "Country";
ws.Cells["AA"].Value = "MyColumn";

Answer 1

您缺少行号吗？

ws.Cells["AA1"].Value = "MyColumn";
