C#中如何将控件中表格数据导出到exeal文档中

1、在项目的引入中,引入Microsoft.Office.Interop.Excel程序集,最好的11.0版本的。

2、在源文件中的using 中,使用using Excel = Microsoft.Office.Interop.Excel;

3、类似函数:


        /// <summary>
        /// 导出Excel的方法
        /// </summary>
        private void ExportExcel(DataGridView ds)
        {
            //DataSet ds = ;//数据源
            if (ds == null) return;

            string saveFileName = "";
            bool fileSaved = false;
            SaveFileDialog saveDialog = new SaveFileDialog();
            saveDialog.DefaultExt = "xls";
            saveDialog.Filter = "Excel|*.xls";
            saveDialog.FileName = "london";

          if (saveDialog.ShowDialog() != System.Windows.Forms.DialogResult.OK)
            {
                return;
            }
            saveFileName = saveDialog.FileName;

            Excel.Application xlApp = new Excel.Application();

            if (xlApp == null)
            {
                MessageBox.Show("未安装Excel");
                return;
            }

            Excel.Workbooks workbooks = xlApp.Workbooks;
            Excel.Workbook workbook = workbooks.Add(Excel.XlWBATemplate.xlWBATWorksheet);
            Excel.Worksheet worksheet = (Excel.Worksheet)workbook.Sheets[1];//取得sheet1

            int index = 0;
            List<string> listExcelColumns = new List<string>();
            //写入字段
            for (int i = 0; i < ds.Columns.Count; i++)
            {
                if (ds.Columns[i].Visible)
                {
                    worksheet.Cells[1, index + 1] = ds.Columns[i].HeaderText;
                    listExcelColumns.Add(ds.Columns[i].Name);
                    index++;
                }
            }
            //写入数值

            for (int r = 0; r < ds.Rows.Count; r++)
            {
                index = 0;
                for (int i = 0; i < ds.Columns.Count; i++)
                {
                    if (ds.Columns[i].Visible)
                    {
                        worksheet.Cells[r + 2, index + 1] = ds.Rows[r].Cells[i].Value;
                        index++;
                    }
                }
                System.Windows.Forms.Application.DoEvents();
            }
            worksheet.Columns.EntireColumn.AutoFit();//列宽自适应。

            int column = 0;
            column = listExcelColumns.IndexOf("UpdateTime") + 1;
            Excel.Range rg = worksheet.get_Range(worksheet.Cells[2, column], worksheet.Cells[ds.Rows.Count + 1, column]);//worksheet.Range[worksheet.Cells[2, column], worksheet.Cells[ds.Rows.Count + 1, column]];
            rg.NumberFormat = "yyyy-MM-dd HH:mm:ss";  // 日期时间列的自定义显示格式,默认的不显示秒

            if (saveFileName != "")
            {
                try
                {
                    workbook.Saved = true;
                    workbook.SaveCopyAs(saveFileName);
                    workbook.SaveAs(saveFileName,
                    fileSaved = true;
                }
                catch (Exception ex)
                {
                    fileSaved = false;
                    MessageBox.Show("保存失败");
                }
            }
            else
            {
                fileSaved = false;
            }
            xlApp.Quit();
            GC.Collect();//强行销毁
            if (fileSaved && System.IO.File.Exists(saveFileName)) System.Diagnostics.Process.Start(saveFileName); //打开EXCEL
        }
    }
