就我而言，如何在 Asp.Net C# 中为 Crystal 报告创建动态连接字符串？

Question

我有多个 iis，所有 iis 网页都连接不同的数据库。我有太多Crystal 报告，一旦我将它上传到所有多个iis，它必须连接到相应的数据库。

我不知道要在 crystal 报告中创建连接字符串。

这是我的 ReportViewer 代码

protected void CrystalReportViewer1_Init(object sender, EventArgs e)
    {
        ReportDocument _rdStudents = new ReportDocument();

        Trace.Write("/CrystalReportFiles/RMS/Inventory/");
        string reportPath = Server.MapPath("~" + Request.QueryString["filename"].ToString());

        _rdStudents.Load(reportPath);
        CrystalReportViewer1.ReportSource = _rdStudents;
    }

如何在这里创建连接字符串。我看到了其中的一些 link。但是我没看懂。

关注这个。

TableLogOnInfos TableLogOnInfos = new TableLogOnInfos();
TableLogOnInfo TableLogOnInfo = new TableLogOnInfo();
ConnectionInfo ConnectionInfo = new ConnectionInfo();
Tables Tables;
ConnectionInfo.ServerName = "ServerName";
ConnectionInfo.DatabaseName = "Database";
ConnectionInfo.UserID = "UserId";
ConnectionInfo.Password = "Password";

ReportDocument _rdStudents = new ReportDocument();
Trace.Write("/CrystalReportFiles/RMS/Inventory/");
string reportPath = Server.MapPath("~" + Request.QueryString["filename"].ToString());

_rdStudents.Load(reportPath);

Tables = _rdStudents.Database.Tables;
    foreach (CrystalDecisions.CrystalReports.Engine.Table table in Tables)
    {
        TableLogOnInfo = table.LogOnInfo;
        TableLogOnInfo.ConnectionInfo = ConnectionInfo;
        table.ApplyLogOnInfo(TableLogOnInfo);
    }
 CrystalReportViewer1.RefreshReport();
 CrystalReportViewer1.ReportSource = _rdStudents;
