RDLC 报告在部署到 IIS 服务器后不显示。它在我正在开发应用程序的同一系统上工作

Question

在 IIS 服务器上发布站点后，RDLC 报告未显示。 如果我在我正在开发应用程序的同一系统上发布，那么它就会显示。

asp.net前端代码如下：

<div class="center-block c-report">
    <asp:UpdatePanel ID="upReport" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
            <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt"
                   CssClass="HideWhenReset" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt"
                   Style="text-align: center" SizeToReportContent="True" Width="100%" Height="100%"
                   InteractiveDeviceInfos="(Collection)">
                   <LocalReport ReportPath="Reports\Total_Report.rdlc">
                   </LocalReport>
            </rsweb:ReportViewer>
        </ContentTemplate>
    </asp:UpdatePanel>
</div>

后台代码如下：

private void BindReport(string ReportPath, DataTable Table)
{
    this.ReportViewer1.LocalReport.ReportPath = ReportPath;
    this.ReportViewer1.LocalReport.DataSources.Clear();
    this.ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", Table));
    if (ReportPath != "Reports\\InformationReports\\MembersMailingLabels.rdlc")
        this.ReportViewer1.LocalReport.SetParameters(new ReportParameter("CompanyName", SystemConfig.GetSystemKeyValue("ClientNameAr", false)));
    this.ReportViewer1.LocalReport.Refresh();
}

从事件日志中得到以下异常：

Answer 1

确保所有与 RDLC 相关的文件都在已发布的文件中。如果它不存在，请从项目文件中复制并粘贴它。您可以尝试以下步骤。

• 将.rdlc文件夹复制到项目目录下的bin文件夹中。
• 再次将您的项目部署到服务器。

Answer 2

除了确保文件实际上在服务器上之外，您还应该使用 HttpServerUtility.MapPath 在 ASP.NET 中正确映射路径。

// Assuming ReportPath is something like '/Reports/MyReport.rdlc'
this.ReportViewer1.LocalReport.ReportPath = HttpContext.Current.Server.MapPath(ReportPath);
