Boa noite tenho este código para gerar um ficheiro excel a partir duma datagrid que funciona na perfeição. O que eu quero fazer é inserir uma linha no excel para criar os titulos das colunas. Podem ajudar.

SaveFileDialog salvar = new SaveFileDialog();

Excel.Application App; // Aplicação Excel
Excel.Workbook WorkBook; // Pasta
Excel.Worksheet WorkSheet; // Planilha
object misValue = System.Reflection.Missing.Value;
App = new Excel.Application();
WorkBook = App.Workbooks.Add(misValue);
WorkSheet = (Excel.Worksheet)WorkBook.Worksheets.get_Item(1);
int i = 0;
int j = 0;

// passa as celulas do DataGridView para a Pasta do Excel
for (i = 0; i <= dataGridView1.RowCount - 1; i++)
{
 for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)
 {
   DataGridViewCell cell = dataGridView1[j, i];
   WorkSheet.Cells[i + 1, j + 1] = cell.Value;
 }
}
// define algumas propriedades da caixa salvar
salvar.Title = "Exportar para Excel";
salvar.Filter = "Arquivo do Excel *.xls | *.xls";
salvar.ShowDialog(); // mostra
// salva o arquivo
WorkBook.SaveAs(salvar.FileName, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue,
Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
WorkBook.Close(true, misValue, misValue);
App.Quit(); // encerra o excel
MessageBox.Show("Exportado com sucesso!");
