dev winform导出功能

 SaveFileDialog fileDialog = new SaveFileDialog();
             fileDialog.Title = "导出Excel";
             fileDialog.Filter = "Excel文件(*.xls)|*.xls";
             DialogResult dialogResult = fileDialog.ShowDialog(this);
             if (dialogResult == DialogResult.OK)
             {
                 try
                 {
                     DevExpress.XtraPrinting.XlsExportOptions options = new DevExpress.XtraPrinting.XlsExportOptions();
                     gridControl1.ExportToXls(fileDialog.FileName);
                     DevExpress.XtraEditors.XtraMessageBox.Show("保存成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                 }
                 catch (Exception ex)
                 {

                     if (ex.Message.Contains("正由另一进程使用"))
                     {
                         DevExpress.XtraEditors.XtraMessageBox.Show("数据导出失败！文件正由另一个程序占用！", "提示");
                     }
                     else
                         DevExpress.XtraEditors.XtraMessageBox.Show("数据导出失败！数据量过大，请分别统计再导出！", "提示");
                 }

             }

注：导出excel列宽度问题
