aspx裡面加2個textbox一個button

.cs檔案裡面程式碼我的伺服器是.

protectedvoidButton1_Click(objectsender,EventArgse)

{

stringconnString=Convert.ToString(ConfigurationManager.ConnectionStrings["sqlconn"]);

SqlConnectionconn=newSqlConnection(connString);//建立資料庫連結

conn.Open();

stringstrsql="select*fromstuentwhereStuName=""+TextBox1.Text+""andStupassword=""+TextBox2.Text+""";

SqlCommandcmd=newSqlCommand(strsql,conn);

SqlDataReaderdr=cmd.ExecuteReader();

if(dr.Read())

{

Session["StuName"]=dr["StuName"];

Session["Stupassword"]=dr["Stupassword"];

if(TextBox1.Text==Session["StuName"].ToString()&&TextBox2.Text==Session["Stupassword"].ToString())

{

Response.Redirect("Default2.aspx");

}

}

else

{

Label1.Text="登陸失敗，請檢測輸入!";

}

}

web.config
