解决方案

  protected   void  btnSubmit_Click（ object  sender，EventArgs e）
 {
 SqlConnection con =  new  SqlConnection （ConfigurationManager.ConnectionStrings [  dbconnection]。ConnectionString）; 
 con.Open（）; 
 SqlCommand cmd =  new  SqlCommand（  select *来自UserInformation，其中UserName = @ username和Password = @ password，con）; 
 cmd.Parameters.AddWithValue（  @ username，txtUserName.Text）; 
 cmd.Parameters.AddWithValue（  @ password，txtPWD.Text）; 
 SqlDataAdapter da =  new  SqlDataAdapter（cmd）; 
 DataTable dt =  new  DataTable（）; 
 da.Fill（dt）; 
  if （dt.Rows.Count> 0）
 {
 Response.Redirect（  Details.aspx）; 
} 
  else  
 {
 ClientScript.RegisterStartupScript（Page.GetType（），  validation，  < script language ='javascript'> alert（'无效的用户名和密码'）< / script>）; 
} 
} 

将代码放入webconfig ....



put rewriter tag

rewrite url =〜/ Login.aspx /(.+）to =〜/ Login.aspx？rurl =

1/并写下这个信号



拿一个（我有comman类）课程。并将此代码放在课堂上.....



公共静态字符串登录（字符串rurl）

{

string url =;

if（rurl ==）

{

url = GetMainUrl（）+登录。 aspx;

}

else

{

if（rurl.StartsWith（/））< br $>
{

url = GetMainUrl（）+Login.aspx+ rurl;

}

else

url = GetMainUrl（）+Login.aspx+/+ rurl;

}

返回网址;

}



现在每个页面在会话到期时都会输入此代码....



if（ session [memberLogin]！= null）

{

}

else

{

Response.Redirect（Common.Login（Request.RawUrl））;

// Cooman意味着我在代码中有上面的comman类< br $>
}





并在bin文件夹urlrewrtier中取一个dll并执行......

解决方案

cmd.Parameters.AddWithValue("@username", txtUserName.Text);
cmd.Parameters.AddWithValue("@password", txtPWD.Text);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
if(dt.Rows.Count>0)
{
Response.Redirect("Details.aspx");
