    StringBuilder sb = new StringBuilder(16);
    foreach (byte b in md5byte)
    {
     i = Convert.ToInt32(b);
    j = i >> 4;
    sb.Append(Convert.ToString(j,16));
    j = ((i << 4) & 0x00ff) >> 4;
    sb.Append(Convert.ToString(j,16));
    }
    sbMD5.Append(f.FullName);
    sbMD5.Append("\t");
    sbMD5.Append(sb.ToString());
    sbMD5.Append("\r\n");
  }
}
Clipboard.SetText(sbMD5.ToString());
 }
 else
  MessageBox.Show("目前剪贴板中数据不可转换为文本","错误");

试试其它关键字

　MD5值　

同语言下

可能有用的
