Question

我收到错误＆＃39;登录失败＆＃39;在尝试在运行时更改我的数据源时。我已经搜索了SO和SAP网站，并从中汇总了下面的代码，但我仍然得到了错误。我的访问数据库是2013年，并且没有密码保护，我使用默认的＆＃34; Admin＆＃34;用户。该报告具有OLE DB连接。我的代码循环遍历所有表，包括子报表并更改登录，我还更改了数据库登录。任何帮助非常感谢：

public void RunTestReport()

        DataSet testDataSet = new DL.NonConformance().GetNonConformances(1, "NonConformance");

        var rpt = new ReportDocument();

        SetCrystalLogin(rpt);

        rpt.SetDataSource(testDataSet);

        crystalReportViewer1.Refresh();

        oConnectInfo.UserID = "Admin";
        oConnectInfo.Password = string.Empty;

        // Set the logon credentials for all tables
        SetCrystalTablesLogin(oConnectInfo, oRpt.Database.Tables);

        // Check for subreports
        foreach (CrystalDecisions.CrystalReports.Engine.Section oSection in oRpt.ReportDefinition.Sections)

        }

        oRpt.Refresh();

        oRpt.SetDatabaseLogon("Admin", string.Empty, dbpath, string.Empty, true);

        oRpt.VerifyDatabase();

        oRpt.Refresh();
