C# 2005 Md5加密后 怎么跟 asp Md5加密不一样!

有没有朋友,能给个正确的,加密后一样的代码..

是一样的

C# 取中间16位,与ASP相同

public static string Md5(string inputString)

MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte[] encryptedBytes = md5.ComputeHash(Encoding.ASCII.GetBytes(inputString));
StringBuilder sb = new StringBuilder();
for (int i = 0; i < encryptedBytes.Length; i++)

sb.AppendFormat("0:x2", encryptedBytes[i]);

return sb.ToString().Substring(8, 16);
参考技术A 是因为字符的编码不一样改成一样的编码就行了，看看这吧

C# 字符串md5加密成16位和32位
