string connStr =ConfigurationSettings.AppSettings[ "ConnString1 "].ToString();
SqlDataSource datasource = new SqlDataSource(connStr, SQL语句);
ReportDocument doc = new ReportDocument();
TableLogOnInfo logininfo = new TableLogOnInfo();
string path;

path = Server.MapPath( "report1.rpt ");
doc.Load(path);
string a, b, c, d;
a = System.Configuration.ConfigurationManager.AppSettings[0];
b = System.Configuration.ConfigurationManager.AppSettings[1];
c = System.Configuration.ConfigurationManager.AppSettings[2];
d = System.Configuration.ConfigurationManager.AppSettings[3];
logininfo.ConnectionInfo.ServerName = a;
logininfo.ConnectionInfo.DatabaseName = b;
logininfo.ConnectionInfo.UserID = c;
logininfo.ConnectionInfo.Password = d;

try
{
doc.Database.Tables[0].ApplyLogOnInfo(logininfo);
doc.Database.Tables[0].SetDataSource(datasource.Select(DataSourceSelectArguments.Empty));
CrystalReportViewer1.ReportSource = doc;
}
catch
{
Response.Write( " <script> alert( '输出报表失败，请检查输入信息或网络！ '); </script> ");
}
