                    Excel.Application excel = new Excel.Application();
                    excel.Visible = true;
                    //true is append parameter
                    using (System.IO.StreamWriter writer = new System.IO.StreamWriter(@"" + textBox2.Text + @"\" + filename.TrimStart() + ".csv", true))
                    writer.WriteLine(text.Replace("|", ","));

我通过此代码获取包含数据的excel文件。但我不能将列标题放入Excel工作表。请告诉我如何添加这些标题

                Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
                Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
                Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();

                if (xlApp == null)
                {
                    System.Windows.MessageBox.Show("Excel is not properly installed!!");
                    return;
                }
                xlWorkBook = xlApp.Workbooks.Add();
                xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);


                xlWorkSheet.Cells[1, 1] = "reg no";
                xlWorkSheet.Cells[1, 2] = "br no"
                xlWorkSheet.Cells[1, 3] = "pr no"
                xlWorkSheet.Cells[1, 4] = "curency";

然后开展业务......

列标题只是Excel（或CSV）中的常规单元格，因此请将它们添加为第一行。

在开始循环之前添加该标题行以写入数据行。
