如何计算字符串的 CRC32

如何计算 .NET 中字符串的 CRC32（循环冗余校验和）？

这家伙似乎已经给你答案了。

博客文章中 Crc32 类的用法：

Crc32 crc32 = new Crc32();
String hash = String.Empty;

using (FileStream fs = File.Open("c:\\myfile.txt", FileMode.Open))
  foreach (byte b in crc32.ComputeHash(fs)) hash += b.ToString("x2").ToLower();

Console.WriteLine("CRC-32 is {0}", hash);
