史蒂芬，你好

转到此处获取VS的CR：

还有样品作为其他参考材料。

是的，您需要3.5 Framework及更高版本的完整版本，让MS保持最新。 我们也可以使用4.7，现在仅需要3.5。

文档创建于2014年，暂停了所有有效文件并保持最新状态，编辑并不会更改创建日期，但它是最新的。

您现在可以在查看器中启用任何导出格式：

//设置格式导出类型：
 int myFOpts =（int）（
     CrystalDecisions.Shared.ViewerExportFormats.RptFormat |
     CrystalDecisions.Shared.ViewerExportFormats.PdfFormat |
     CrystalDecisions.Shared.ViewerExportFormats.RptrFormat |
     CrystalDecisions.Shared.ViewerExportFormats.XLSXFormat |
     CrystalDecisions.Shared.ViewerExportFormats.CsvFormat |
     CrystalDecisions.Shared.ViewerExportFormats.EditableRtfFormat |
     CrystalDecisions.Shared.ViewerExportFormats.ExcelRecordFormat |
     CrystalDecisions.Shared.ViewerExportFormats.RtfFormat |
     CrystalDecisions.Shared.ViewerExportFormats.WordFormat |
     CrystalDecisions.Shared.ViewerExportFormats.XmlFormat |
     CrystalDecisions.Shared.ViewerExportFormats.ExcelFormat |
     CrystalDecisions.Shared.ViewerExportFormats.ExcelRecordFormat）;
//CrystalDecisions.Shared.ViewerExportFormats.NoFormat）; //不允许出口
//int myFOpts =（int）（CrystalDecisions.Shared.ViewerExportFormats.AllFormats）;

 crystalReportViewer1.AllowedExportFormats = myFOpts;

 尝试导出：

 如果（ExportTypeSelected ==" crReportExportFormatXLSX"）
 #region XLSX
 {
    //这项工作不会改变
    //这将获取报告名称，并将导出名称设置为与扩展名相同的名称
     字符串outputFileName ="";
     字符串MyRptName = rpt.FileName.ToString（）;
     outputFileName = MyRptName.Substring（9，rpt.FileName.Length-9）;
     outputFileName = outputFileName.Substring（0，（outputFileName.Length-3））+" xlsx";

     尝试
     {

        //保存修改后的信息
        //rptClientDoc.set_SavedExportOptions(CrReportExportFormatEnum.crReportExportFormatXLSX，RASXLXSExportOpts）;

         CrystalDecisions.ReportAppServer.ReportDefModel.ExportOptions exportOpts1 =新的CrystalDecisions.ReportAppServer.ReportDefModel.ExportOptions（）;

 您将需要测试并使用代码，不确定在编写本文时我正在测试什么...
