C # operation when receiving user input password to confirm

First create a new original form, as follows:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;namespacewindowsformsapplication11{ Public Partial classForm1:form { PublicForm1 () {InitializeComponent (); }        Private voidTssave_click (Objectsender, EventArgs e) {            if(RDB02. Checked) {frmpwd F=Newfrmpwd (); F.formclosed+=NewFormclosedeventhandler (f_formclosed);//Event NotificationF.showdialog (); }            Else{test (); }                    }        voidTest () {MessageBox.Show ("Test"); }               voidF_formclosed (Objectsender, Formclosedeventargs e) {            if(Sender asFRMPWD). Ispass)//Ispass is the defined global variable in the form that receives the password input, and sender is the parameter that triggers the event.{test (); }            Else{MessageBox.Show ("Password Error"); }        }    }}

Forms that the password receives:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;namespacewindowsformsapplication11{ Public Partial classFrmpwd:form { Public BOOLIspass =false;//If the password is correct, the assignment is true and the default is False         Publicfrmpwd () {InitializeComponent (); }        Private voidButton1_Click (Objectsender, EventArgs e) {            stringStrpwd = This. TextBox1.Text.Trim (); if(Strpwd = ="12345") {Ispass=true; }             This.            Hide ();  This.        Close (); }    }}

The following conditions are required to verify the password:

You do not need to verify the password as follows, directly execute the corresponding function:
