如何在c#中创建md5文件

Question

如何在c#中创建md5？我想调用txt文件，并调用c#中的md5到txt文件来哈希它。

public static string MD5Hash(string text)
{
    System.Security.Cryptography.MD5 md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
    return System.Text.RegularExpressions.Regex.Replace(BitConverter.ToString(md5.ComputeHash(ASCIIEncoding.Default.GetBytes(text))), “-”, “”);
}

直接从此处窃取。

protected string GetMD5HashFromFile(string fileName)
{
  FileStream file = new FileStream(fileName, FileMode.Open);
  MD5 md5 = new 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();
}
