给你一个md5 加密的类。绝对正确

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

public class MD5
{

public static string getMD5(string encryptStr)
{
System.Security.Cryptography.MD5 md5 = new MD5CryptoServiceProvider();
byte[] bytResult = md5.ComputeHash(System.Text.Encoding.Default.GetBytes(encryptStr));
string strResult = BitConverter.ToString(bytResult);
strResult = strResult.Replace("-", "");
return strResult;
}
}

/// <summary>
/// 得到MD5加密密码
/// </summary>
/// <param name="str"></param>
/// <returns></returns>
public static string MD5(string str)
{
str = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str, "MD5");
return str;
}

#region MD5加密
public static string MD5(string number)
{
ASCIIEncoding ASCIIenc = new ASCIIEncoding();
string strReturn = "";
byte[] ByteSourceText = ASCIIenc.GetBytes(number);
MD5CryptoServiceProvider Md5Hash = new MD5CryptoServiceProvider();
byte[] ByteHash = Md5Hash.ComputeHash(ByteSourceText);
foreach (byte b in ByteHash)
{
strReturn += b.ToString("x2");
}
return strReturn;
}
#endregion

调用方法：
Textbox1.text=MD5("sdfdsfsdf");

public string MD5(string str)
{
MD5 md5 = new MD5CryptoServiceProvider();
byte[] data = System.Text.Encoding.Default.GetBytes(str);
byte[] result = md5.ComputeHash(data);
string ret = "";
for (int i = 0; i < result.Length; i++)
ret += result[i].ToString("x").PadLeft(2, '0');
return ret;
}
