MD5
用时没找到工具，自己写了个，函数如下：
private string GetMD5HashFromFile(string fileName)
{
try
{
FileStream file = new FileStream(fileName, FileMode.Open);
System.Security.Cryptography.MD5 md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
byte[] retVal = md5.ComputeHash(file);
file.Close();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < retVal.Length; i++)
{
sb.Append(retVal[i].ToString("x2"));
}
return sb.ToString();
}
catch (Exception ex)
{
throw new Exception("GetMD5HashFromFile() fail,error:" + ex.Message);
}
}
