TableLogOnInfo logOnInfo = new TableLogOnInfo ();

修改代码：并添加引用
using CrystalDecisions.Shared ;//负责解释TableLogOnInfo类
using CrystalDecisions.CrystalReports .Engine ;//负责解释ReportDocument类private void Page_Load(object sender, System.EventArgs e)
{
TableLogOnInfo logOnInfo = new TableLogOnInfo ();
//这里必须事先申明一个ReportDocument对象 Report，同时加载数据报表
ReportDocument oRpt = new ReportDocument();
oRpt.Load("c:\\inetpub\\wwwroot\\exer\\pagelet\\crystal\\cr1.rpt");//修改为你自//己的正确位置

//建立安全信息
//受密码保护的 Microsoft Access 和 Paradox 等 PC 数据库也使用该方法，但 LogOnInfo.ServerName //和 LogOnInfo.DatabaseName 要保留为空
logOnInfo.ConnectionInfo.ServerName = "www";
logOnInfo.ConnectionInfo.DatabaseName = "archives";
logOnInfo.ConnectionInfo.UserID = "sa";
logOnInfo.ConnectionInfo.Password = "123456";

oRpt.Database .Tables [0].ApplyLogOnInfo (logOnInfo);

//建立.rpt文件与CryStalReportviewer文件之间的连接
CrystalReportViewer1.ReportSource = oRpt;
}
