Question

使用单击一次部署在我的客户端计算机上安装C＃Windows应用程序后，部署工作一切正常，除了使用水晶报表的“报表”部分。报表尝试加载后，我将面临以下异常：

************** Exception Text **************
CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException: The document has not been opened.

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

下面是cmbAfterSel_SelectedIndexChanged的代码

                if (dt.Rows.Count == 0)
                {
                    MessageBox.Show("No data found for the selected criteria", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
                }
                else
                {
                    CrystalReport1 CR = new CrystalReport1();
                    CR.Load(@"C:\Users\User\Documents\Visual Studio 2010\Projects\Project1\Project1\CrystalReport\CrystalReport1.rpt");
                    CR.SetDataSource(dt);

                    crystalReportViewer1.ReportSource = CR;
                    crystalReportViewer1.RefreshReport();
                }

我已经为.net框架安装了Crystal Reports运行时引擎。

理想情况下，报告应使用来自数据库（SQL Server 2012 Express）的数据打开。在完成开发的PC上，报告运行良好。

在客户端计算机上运行Crystal Report时发生异常
