各位大侠，我搞个登陆页面，但都是有问题的，本人菜鸟，帮我看看要怎么改才对
代码是
<add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
--------------------
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection sqlcon = new SqlConnection();
sqlcon.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
sqlcon.Open();
string sql1 = "select * from Table1 WHERE name='" + name.Text + " ' and paw='" + paw.Text + " '";
SqlCommand sqlcmd = new SqlCommand(sql1, sqlcon);
SqlDataReader ss = sqlcmd.ExecuteReader();
if (ss.Read())
{
Label1.Text = name.Text;
}
}
---------------------
运行当当按按钮时候提示：
“/Documents1”应用程序中的服务器错误。
