水晶报表项目运行时 去掉 输入连接数据库密码 的页面

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：

[HTML] 纯文本查看 复制代码

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

2.具体代码：

[C#] 纯文本查看 复制代码

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：

[C#] 纯文本查看 复制代码

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