c# - page load on validate user -


i want ask how load page using validate user using request string. have code below:

protected void page_load(object sender, eventargs e) {    string validateuser = request.querystring["inisial"];     if (validateuser != null)     {         response.redirect("home.aspx");     }     string x = request.querystring["ind"];     if (validateuser != null)     {       response.redirect("home.aspx");     } } protected void validateuser(object sender, eventargs e) {     int userid = 0;     string constr = configurationmanager.connectionstrings["dbconn"].connectionstring;     using (sqlconnection con = new sqlconnection(constr))     {         using (sqlcommand cmd = new sqlcommand("validate_user"))         {             cmd.commandtype = commandtype.storedprocedure;             cmd.parameters.addwithvalue("@username", request.querystring["inisial"]);             cmd.parameters.addwithvalue("@password", request.querystring["ind"]);             cmd.connection = con;             con.open();             userid = convert.toint32(cmd.executescalar());             con.close();         }         switch (userid)         {             case -1:                 login1.failuretext = "username and/or password incorrect.";                 break;             case -2:                 login1.failuretext = "account has not been activated.";                 break;             default:                 formsauthentication.redirectfromloginpage(login1.username, login1.remembermeset);                 break;         }     } }

i tried login system using request string change username , password url:

http://default.aspx?id_sistem=24&inisial=gdm&ind=7/17/2004 4:50:40 pm

example : username = (gdm), password = (7/17/2004 4:50:40)

please correct me if i'm wrong thanks

i don't think should use query string in url username , password, suggest creating method user authenticated , set session variable stores bool whether user authenticated or not.

    protected void page_load(object sender, eventargs e)     {         if (session["authenticated"] != null)         {             bool authenticated = convert.toboolean(session["authenticated"]);             if (!authenticated)             {                 response.redirect("~/home.aspx");             }          }      }
