1.把连接数据库的代码写在web.config文件中

    在 <connectionStrings> </connectionStrings>中加入以下代码:

    <add name="Data Source" connectionString="***.***.***.***" />
    
<add name="Initial Catalog" connectionString="******" />
    
<add name="User ID" connectionString="******" />
    
<add name="Password" connectionString="******" />

 

2.具体代码:

    public class CrystalHelper
    {
        
public void NoPasswd(CrystalReportViewer crystalReportViewer, string
 path1)
        {
            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();
            
//
获取.rpt文件真实路径
            
//path1 = Microsoft.SqlServer.Server.MapPath("~/Pages/ARC/ARCjp.rpt");


            oRpt.Load(path1);

            
//从web.config中获取logOnInfo参数信息
            string a, b, c, d;
            
//获取ServerName

            a = ConfigurationManager.ConnectionStrings["Data Source"].ConnectionString;
            
//获取DatabaseName

            b = ConfigurationManager.ConnectionStrings["Initial Catalog"].ConnectionString;
            
//获取UserId

            c = ConfigurationManager.ConnectionStrings["User ID"].ConnectionString;
            
//获取password

            d = ConfigurationManager.ConnectionStrings["Password"].ConnectionString;
            
//设置logOnInfo参数


            logOnInfo.ConnectionInfo.ServerName 
= a;
            logOnInfo.ConnectionInfo.DatabaseName 
=
 b;
            logOnInfo.ConnectionInfo.UserID 
=
 c;
            logOnInfo.ConnectionInfo.Password 
=
 d;

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

            
//建立.rpt文件与CryStalReportviewer文件之间的连接

            crystalReportViewer.ReportSource = oRpt;
        }
    }

 

3.在调用水晶报表文件的页面的***.cs页面中调用2中的方法:

            CrystalHelper cry = new CrystalHelper();
            cry.NoPasswd(CrystalReportViewer1, Server.MapPath(
"~/Pages/Arc/ArcJp.rpt"
));
