【问题描述】：

我需要帮助从 datagridview 列和标题导出数据，下面我将添加我用于从 datagridview 导出到 excel 的代码，它可以将所有数据从 datagridview 发送到 excel 表唯一问题是标题没有被发送到工作表。你们能帮忙解决我需要在此处添加的那部分内容，以便标题也显示在工作表中。

private void ImportDataGridViewDataToExcelSheet()
{

            string userID = WindowsIdentity.GetCurrent().Name;
            var userName = userID.Remove(0, 15);
            //test.Text = userName;
            //dataGridView_ShowAllData
            Excel.Application xlApp;
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;

            Int16 i, j;

            xlApp = new Excel.Application();
            xlWorkBook = xlApp.Workbooks.Add(misValue);

            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            for (i = 0; i <= dataGridView_ShowAllData.RowCount - 2; i++)
            {
                for (j = 0; j <= dataGridView_ShowAllData.ColumnCount - 1; j++)
                {
                    xlWorkSheet.Cells[i + 1, j + 1] = dataGridView_ShowAllData[j, i].Value.ToString();
                }
            }

            xlWorkBook.SaveAs(@"C:\Users\" + userName + "\\Downloads\\ReportView.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
            xlWorkBook.Close(true, misValue, misValue);
            xlApp.Quit();

            releaseObject(xlWorkSheet);
            releaseObject(xlWorkBook);
            releaseObject(xlApp);
        }

        private void releaseObject(object obj)
        {
            try
            {
                System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
                obj = null;
            }
            catch (Exception ex)
            {
                obj = null;
                MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
            }
            finally
            {
                GC.Collect();
            }
        }

        private void toolStripMenuItem_ImportDGVToExcel_Click(object sender, EventArgs e)
        {
            ImportDataGridViewDataToExcelSheet();
        }
