首先建立一個原始表單,如下:

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication11{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void tsSave_Click(object sender, EventArgs e)        {            if (rdb02.Checked)            {                FrmPwd f = new FrmPwd();                f.FormClosed += new FormClosedEventHandler(f_FormClosed);  //事件通知                f.ShowDialog();            }            else             {                test();            }                    }        void test()        {            MessageBox.Show("test");        }               void f_FormClosed(object sender, FormClosedEventArgs e)        {            if ((sender as FrmPwd).isPASS)//isPASS 為接收密碼輸入的那個表單裡面的定義的全域變數,sender 為觸發這個事件的參數            {                test();            }            else             {                MessageBox.Show("密碼錯誤");            }        }    }}

 

密碼接收的表單:

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication11{    public partial class FrmPwd : Form    {        public bool isPASS = false; //如果密碼正確,則賦值為true,預設為false        public FrmPwd()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            string strPwd = this.textBox1.Text.Trim();            if (strPwd == "12345")            {                                isPASS = true;                           }            this.Hide();            this.Close();        }    }}

 

需要校正密碼的情況如下:

 

 

不需要校正密碼的情況如下,直接執行對應的函數:
