Silverlight 数据导出(Excel,word)

　　目前项目使用第三方空间Telerik RadControls，在数据导出方面提供便利

　　可以直接使用RadGridView，将GridView中数据导出为需要的格式。

//表格数据导出
private void btn_export_Click(object sender, RoutedEventArgs e)
 {
            string extension = "";
            ExportFormat format = ExportFormat.Html;
            RadComboBoxItem comboItem = this.rcb_format.SelectedItem as RadComboBoxItem;
            string selectedItem = comboItem.Content.ToString();

            switch (selectedItem)
            {
                case "Excel": extension = "xls";
                    format = ExportFormat.Html;
                    break;
                case "ExcelML": extension = "xml";
                    format = ExportFormat.ExcelML;
                    break;
                case "Word": extension = "doc";
                    format = ExportFormat.Html;
                    break;
                case "Csv": extension = "csv";
                    format = ExportFormat.Csv;
                    break;
            }

            SaveFileDialog dialog = new SaveFileDialog();
            dialog.DefaultExt = extension;
            dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, selectedItem);
            dialog.FilterIndex = 1;

            if (dialog.ShowDialog())
            {
                using (Stream stream = dialog.OpenFile())
                {
                    GridViewExportOptions exportOptions = new GridViewExportOptions();
                    exportOptions.Format = format;
                    exportOptions.ShowColumnFooters = true;
                    exportOptions.ShowColumnHeaders = true;
                    exportOptions.ShowGroupFooters = true;
                    this.radgridview.Export(stream, exportOptions);
                }
            }
 }

* RadGridView到处为Excel是带有HTML元素的xls表格，在用OLEDB打开会 提示“外部表不是预期的格式。”，为以后方便导入，到处为CSV文件最合适。
