c# code to give Gridview cell name to exporting Excel file

Sir,

I am in winForm project in which I have to export datagridview data into excel sheet.

I have done almost except naming exported excel header columns to that of datagridview.

How can I set column headers to the exported excel file..help me

for (int i = 0; i < dgvBankAllocationReport.Rows.Count; i++)

{

for (int j = 0; j < dgvBankAllocationReport.Columns.Count; j++)

{

if (dgvBankAllocationReport.Rows[i].Cells[j].Value != null)

{

exceObj.Cells[i + 2, j + 1] = dgvBankAllocationReport.Rows[i].Cells[j].Value;

string colName = dgvBankAllocationReport.Columns[j].HeaderText;

}
