C#中實現MD5加密

1.新建一個Windows應用程序，添加兩個TextBox文本框，一個按鈕；

2.添加一個類md5,引入命名空間：using System.Security.Cryptography。類md5代碼如下：

using System;
using System.Collections.Generic;
using System.Text;
using System.Security.Cryptography;

namespace Windows
{
    class md5
    {
        public static String EncryptCode(string passWord)
        {
            Byte[] clearBytes = new UnicodeEncoding().GetBytes(passWord);
            Byte[] hashedBytes = ((HashAlgorithm)CryptoConfig.CreateFromName("MD5")).ComputeHash(clearBytes);

            return BitConverter.ToString(hashedBytes);
        }
    }
}

然後在窗體的按鈕事件裡寫如下代碼：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Security.Cryptography;
namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
  
        public Form1()
