實現c#輸入文字框中的字串改變使另外一個文字框文字輸出MD5加密值也實時變化。

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 WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        private string a;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        public string EncodePassword(string pwd)
        {
            //獲取要加密的欄位，並轉化為Byte[]陣列 
            byte[] data = System.Text.Encoding.Unicode.GetBytes(pwd.ToCharArray());
            //建立加密服務 
            System.Security.Cryptography.MD5 md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
            //加密Byte[]陣列 
            byte[] result = md5.ComputeHash(data);
            //將加密後的陣列轉化為欄位 
            return System.Text.Encoding.Unicode.GetString(result);
        }


        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            textBox2.Text = EncodePassword(textBox1.Text.Trim());
        }

        private void textBox2_TextChanged(object sender, EventArgs e)
        {
        }
   }
}
 

具體效果就這樣了，
