I think this is what GIT does, so I just want to learn how to do it

推荐答案

using (FileStream stream = File.OpenRead(@"C:\File.ext"))
{
    using (SHA1Managed sha = new SHA1Managed())
    {
        byte[] checksum = sha.ComputeHash(stream);
        string sendCheckSum = BitConverter.ToString(checksum)
            .Replace("-", string.Empty);
    }
}

定期计算校验和.
