我用.net4.0在vs2010中创建了一个水晶报告.当我发布网站时,它会抛出错误"由JRC引擎处理的文档无法在C++堆栈中打开".我在服务器上发布了这个网站,我正在尝试从客户端访问它,我确实在app_code中记录了.rpt文件,但又一次得到了同样的错误.所以我创建了一个文件夹wwwroot,在该文件夹中我保存了asp_client和网站文件夹,并给了wwwroot的物理路径.一切正常,除了水晶报告.在.cs文件代码如下:

    ReportDocument rptDoc = new ReportDocument();
    DataSetForCrystalReport ds = new DataSetForCrystalReport();
    DataSetForCrystalReport dsHeader = new DataSetForCrystalReport();
    DataTable dt = new DataTable();
    DataTable dtHeader = new DataTable();
    dt.TableName = "dtBill";
    string ReceiptNo = Request.QueryString["ReceiptNo"];
    dt = getAllOrders(ReceiptNo).Tables[0];
    dtHeader = TblcompanysettingsService.GetOrganizationDetails();
    ds.Tables[1].Merge(dt);
    ds.Tables[2].Merge(dtHeader);
    rptDoc.Load(Server.MapPath("crBill.rpt"));
    rptDoc.SetDataSource(ds);
    CrystalReportViewer1.ReportSource = rptDoc;

堆栈错误的痕迹:
