如何在我的ASP.NET项目中连接数据库文件 [英] How to connect database file in my ASP.NET project
问题描述
我已经调整了数据库，当我连接sql它显示服务器名称空白我输入[。]点它连接。
当我运行我的asp.net web应用程序时显示实例错误。
我的连接字符串是：
< add name =WarehouseWebsiteStringconnectionString =Data Source = hostingmssql10; Network Library = dbmssocn; Connection Timeout = 15;数据包大小= 4096;集成安全性=否;用户ID = bea3de-warehousebissdscom;加密=否;初始目录= bea3de-warehousebissdscom;密码= 1234;
providerName =System.Data。 SqlClient/>
i使用数据库创建登录页面但是没有登录给出错误
< b>我尝试过：
使用System;
使用System.Collections.Generic;
使用System.Linq;
使用System.Web;
使用System.Web.UI;
使用System.Web.UI .WebControls;
使用System.Web.Security;
使用System.Data.SqlClient;
使用System.Web.Configuration;
公共部分类AdminLogin：System.Web.UI。页面
{
SqlConnection con = new SqlConnection（WebConfigurationManager.ConnectionStrings [WarehouseWebsiteString]。ToString（））;
protected void Page_Load（对象发送者，EventArgs e）
{
error.Visible = false;
}
protected void imgBtnLogin_Click（object sender，ImageClickEventArgs e）
{
try
{
using（con = new SqlConnection（WebConfigurationManager.ConnectionStrings [WarehouseWebsiteString]。ToString（）））
{
// string username = txtUserName.Text;
// string password = txtPassword.Text;
con.Open（） ;
string qry =s select * from tblLoginDetails其中UserName ='+ txtUserName.Text +'和Password ='+ txtPassword.Text +';
SqlCommand cmd = new SqlCommand（qry，con）;
int count = Convert.ToInt32（cmd.ExecuteScalar（））;
if（count == 1）
{
Session [UserName] = txtUserName.Text.Trim（）;
Response.Redirect（〜/ Admin / Default.aspx）;
error.Visible = false;
}
其他
{
错误。可见=真;
}
}
con.Close（）;
}
catch（例外情况）
{
回复.Write（ex.Message）;
}
}
}
但是它不工作我不明白我在哪里做改变。

推荐答案
当我在 configration 文件中执行此操作时它正常工作： -
When i do this in configration file It working properly:-
<connectionStrings>
<!--<add name="WarehouseWebsiteString" connectionString="Data Source=BISWEBSERVER\SQLSERVER2005; DataBase=Warehouse; User Id=sa; Password=xfiles_76;"/>-->
<add name="WarehouseWebsiteString" connectionString="Data Source=. ;Network Library=dbmssocn;Connection Timeout=15;Packet Size=4096;Integrated Security=no;User ID=warehousebissdscom; Encrypt=no;Initial Catalog=warehousebissdscom; Password=123;Trusted_Connection=true;"/>
</connectionStrings>
