c＃ReportViewer Export

在ReportView我想导出为以下格式：.docx，.pdf或.xlsx

导出到.pdf：

 reportViewer.ExportDialog(_reportViewer.LocalReport.ListRenderingExtensions()[3]); 

导出到.docx：

 reportViewer.ExportDialog(_reportViewer.LocalReport.ListRenderingExtensions()[5]); 

导出到.xlsx：

 reportViewer.ExportDialog(_reportViewer.LocalReport.ListRenderingExtensions()[1]); 

但首先我必须选择一种保存格式。 我想首先打开SaveFileDialog并在其中选择一种保存格式

我该怎么做 ？

这是我提出的代码：

 string _sSuggestedName = String.Empty; byte[] byteViewerPDF = _reportViewer.LocalReport.Render("PDF"); byte[] byteViewerExcel = _reportViewer.LocalReport.Render("Excel"); byte[] byteViewerWord = _reportViewer.LocalReport.Render("Word"); SaveFileDialog saveFileDialog1 = new SaveFileDialog(); saveFileDialog1.Filter = "PDF files (*.pdf)|*.pdf| Doc files (*.doc)|*.doc| Excel files (*.xls)|*.xls"; if (saveFileDialog1.ShowDialog() == DialogResult.Ok) { FileStream newFile = new FileStream(saveFileDialog1.FileName, FileMode.Create); if (saveFileDialog1.FilterIndex == 1) { newFile.Write(byteViewerPDF, 0, byteViewerPDF.Length); newFile.Close(); } else if (saveFileDialog1.FilterIndex == 2) { newFile.Write(byteViewerWord, 0, byteViewerWord.Length); newFile.Close(); } else if (saveFileDialog1.FilterIndex == 3) { newFile.Write(byteViewerExcel, 0, byteViewerExcel.Length); newFile.Close(); } }
