c#获取MD5值

C#里面如何获取MD5值。我现在已经晕了。网上的基本上都是一下没有什么用的。我要标准版的MD5.

Answer 1

using System.Security.Cryptography;
public string GetMd5(string source)
{
HashAlgorithm hashAlgorithm = null;
hashAlgorithm = new MD5CryptoServiceProvider();
byte[] byteValue;
byteValue = Encoding.UTF8.GetBytes(source);
byte[] hashValue;
hashValue = hashAlgorithm.ComputeHash(byteValue);
string Value = null;
int i;
for (i = 0; i <= 15; i++)
{
string bit;
bit = Convert.ToString(hashValue[i], 16);
if (bit.Count() == 1) { bit = "0" + bit; };
Value = Value + bit;
}
return Value;
}
