// 在此处放置用户代码以初始化页面
}
#region Web 窗体设计器生成的代码

InitializeComponent();
base.OnInit(e);
}

private void InitializeComponent()
{
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Button2.Click += new System.EventHandler(this.Button2_Click);
this.Load += new System.EventHandler(this.Page_Load);
}
#endregion
private void Button2_Click(object sender, System.EventArgs e)
{ Response.Redirect ( "WebForm2.aspx? ");
}
private void Button1_Click(object sender, System.EventArgs e)
{
string s_name= nameTextBox.Text .Trim ();
string s_Password =PasswordTextBox.Text .Trim ();
string strsel = "select name,Password from userdata where name = ' "+s_name+ " ' and Password = ' "+s_Password+ " ' ";
//string strsel = "select User_Name,User_Password from Info_userdata where name = ' "+s_name+ " ' ";
SqlConnection cn = new SqlConnection( "server=ED32E0D74620400;uid=sa;pwd=;database=kang ");
SqlCommand cmd = new SqlCommand(strsel, cn);
cn.Open();
SqlDataReader myDr = cmd.ExecuteReader();
if(myDr.Read())
{
this.Visible=false;
Response.Redirect ( "WebForm3.aspx? ");
}
else
{
Response.Write( "密码和用户不一致 ");
}
myDr.Close();
cn.Close();
}
[解决办法]
if(myDr.Read())
{
this.Visible=false;
Response.Redirect ( "WebForm3.aspx? ");
Session[ "s_name "]=s_name;
}
