带有子报告的crystal report不在生产/测试机器C#winforms上工作

我已经创建了包含8个子报告的crystal report（使用VS 2010）。我创建了存储过程，它填充链接到主报表和子报表的所有转储SQL server表。我的代码在开发机器上运行良好，但当它部署到另一台机器上时，它会抛出以下错误

无法打开连接。
详细信息：[数据库供应商代码17]
无法打开连接。
rpt_reportName{GUID}.rpt

下面是我生成报告的代码

ReportDocument crReportDocument;
        Boolean TypesDSReports = false;
        clsErrorLog oLog = new clsErrorLog();

        static TableLogOnInfo crTableLogonInfo;
        static ConnectionInfo crConnectionInfo;
        static Tables crTables;
        static Database crDatabase;
 public static void ReportLogin(ReportDocument crDoc, string Server, string Database, string UserID, string Password)
        {
            crConnectionInfo = new ConnectionInfo();
            crConnectionInfo.ServerName = Server;
            crConnectionInfo.DatabaseName = Database;
            crConnectionInfo.UserID = UserID;
            crConnectionInfo.Password = Password;
            crDatabase = crDoc.Database;
            crTables = crDatabase.Tables;
            foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in crTables)
            {
                crTableLogonInfo = crTable.LogOnInfo;
                crTableLogonInfo.ConnectionInfo = crConnectionInfo;
                crTable.ApplyLogOnInfo(crTableLogonInfo);
            }

            //crDoc.Subreports["aa"].co = crConnectionInfo;

        }




private void DisplayReportWithSubReport()
        {
            try
            {
                ReportDocument crReportDocument = new ReportDocument();
                crReportDocument.Load(sReportPath.Trim());

                ReportLogin(crReportDocument, clsCustomize.gsPropServerName, clsCustomize.gsPropCurrentDataBaseName, clsCustomize.gsPropDataBaseUserID, clsCustomize.gsPropDataBasePassword);
                crReportDocument.Refresh();
                CRViewer.ReportSource = crReportDocument;
                CRViewer.RefreshReport();
                this.Text = sDisplayReportCaption;

                if (TypesDSReports == false)
                {
                    crReportDocument.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperA4;
                }
                this.WindowState = FormWindowState.Maximized;

                if (HMS.Common.clsConstants.gbPropCloseReportForm == true)
                {

                    crReportDocument.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperA4;
                    if (HMS.clsCustomize.giNoOfPrintCopies == 0)
                    {
                        HMS.clsCustomize.giNoOfPrintCopies = 1;
                    }

                    crReportDocument.PrintToPrinter(HMS.clsCustomize.giNoOfPrintCopies, false, 1, 1);
                    HMS.Common.clsConstants.gbPropCloseReportForm = false; //Reset the Flag
                    this.Close();
                }
                else
                {
                    this.WindowState = FormWindowState.Maximized;
                }
            }
            catch (Exception ex)
            {
                oLog.LogError(ex, "", "", "", "");
            }


        }

开发机器和目标机器都有相同的系统配置。请问问题出在哪里

问候,，

我不是100%同意这一点，但我非常确定，仅在顶层设置连接信息是不够的。您需要在子报表/表中循环，并对每个子报表/表应用logonInfo

crDoc.Subreports[x].Database.Tables[y].ApplyGonInfo（crTableLogonInfo）.

我自己找到了解决方案。我在ReportLogin方法中添加了以下代码，它工作得非常好

 for (int i = 0; i < crDoc.Subreports.Count; i++)
                {
                    crDoc.Subreports[i].SetDatabaseLogon(UserID, Password, Server, Database);
                }

for（int i=0；i

我完全同意Jonathan的观点，我们还需要在子报告级别提供连接信息。我在下面添加了我的代码。
