正在研究CrystalReport，下面的代码为当sql server密码不为空时的写法

　　ReportDocument rptDoc = new ReportDocument(); rptDoc.Load("x:\\crystalreport\\crPull.rpt"); TableLOGOnInfo LOGOnInfo = new TableLOGOnInfo(); LOGOnInfo = rptDoc.Database.Tables["tblMagUserInfo"].LOGOnInfo; ConnectionInfo connectionInfo = new ConnectionInfo(); connectionInfo = LOGOnInfo.ConnectionInfo; connectionInfo.ServerName = "myserver"; connectionInfo.DatabaseName = "mydb"; connectionInfo.UserID = "myid"; connectionInfo.Password = "mypwd"; rptDoc.Database.Tables["tblMagUserInfo"].ApplyLOGOnInfo(LOGOnInfo); CrystalReportViewer1.ReportSource = rptDoc;
