我创建了一个 RDLC 报告，当我在网络浏览器中显示它时它工作正常。但是我的客户现在希望我将 PDF 文件发送到浏览器/客户端，而不是在 Web 浏览器中显示报告。当我添加代码以创建报表的 PDF 并将其发送到客户端/浏览器时，我遇到了错误。这是我将 PDF 发送到客户端/浏览器的代码：

 <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData"
    TypeName="CourrierExpress.ExpressCourierDataSetTableAdapters.uspFrontEnd_Invoice_PrintInvoiceTableAdapter"
    OldValuesParameterFormatString="original_{0}">
    <SelectParameters>
        <asp:QueryStringParameter Name="InvoiceId" QueryStringField="InvoiceId" Type="Int64"
            DefaultValue="" />
    </SelectParameters>
</asp:ObjectDataSource>

我在页面加载后调用此代码：

 Int64 invoiceId = int.Parse(Request.QueryString["InvoiceId"]);
        Warning[] warnings;
        string[] streamIds;
        string mimeType;
        string encoding;
        string extension;

        var rds = new ReportDataSource { DataSourceId = "ObjectDataSource1", Name = "DataSet1" };

        var viewer = new ReportViewer();
        viewer.ProcessingMode = ProcessingMode.Local;
        viewer.LocalReport.DataSources.Clear();
        viewer.LocalReport.ReportPath = "Reports/ReportInvoicePrint.rdlc"; //This is your rdlc name.
        viewer.LocalReport.DataSources.Add(rds);
        var bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension,
                                                 out streamIds, out warnings);

        Response.Buffer = true;
        Response.Clear();
        Response.ContentType = mimeType;
        Response.AddHeader("content-disposition", "attachment; filename= filename" + "." + extension);
        Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file  
        Response.Flush(); // send it to the client to download  
        Response.End();

RDLC 报告具有名为“DataSet1”的数据集。错误截图是： 在此处输入图像描述

为“Dataset1”示例提供任何其他名称：“MyDataSourceName”和数据源“StudentList”这是我转换为列表的数据源

ReportDataSource rds = new ReportDataSource("MyDataSourceName", StudentList);
