c# - Yes/NO window appears even when Password is correct - 


private void button1_click(object sender, eventargs e)     {          try         {             var sr = new system.io.streamreader("c:\\" + textbox1.text + "\\login.txt");             username = sr.readline();             password = sr.readline();             email    = sr.readline();             sr.close();           if  (username == textbox1.text && password == passwordtextbox.text)                 messagebox.show("you logged in.");              else            messagebox.show("username or password seems invalid, please use email recover password/username");           form2 frm = new form2();           // if            frm.show();           //frm.show();           frm.mypass = password;           frm.myid = username;               }         catch(system.io.directorynotfoundexception )         {             messagebox.show("error, please correct username/pass or recover");           }     }

so, problem form2 recoverypassword question yes/no, in user presses yes, prompts them input email send password, , pressing no, return main screen. however, problem form yes/no should appear if password wrong, appears when password right. how should fix ?

what tried put these lines

form2 frm = new form2();           // if            frm.show();           //frm.show();           frm.mypass = password;           frm.myid = username;

in if statement, didn't work showed me error invalid expression else. don't know else work. if can help, please do. thank you.

here's code, indented:

if (username == textbox1.text && password == passwordtextbox.text)     messagebox.show("you logged in."); else      messagebox.show("username or password seems invalid, please use email recover password/username");  form2 frm = new form2(); frm.show(); frm.mypass = password; frm.myid = username;

you need curly braces group logic together:

else {     messagebox.show("username or password seems invalid, please use email recover password/username");      form2 frm = new form2();     frm.show();     frm.mypass = password;     frm.myid = username; }

i'd suggest replacing show() showdialog(), prevent user interacting first form while second open, , prevent code continuing run , trying password , username before user has entered them.
