摘要：因工作需要对文件进行是否被修改判断，整理的一段生成文件MD5码的代码： 1: public class FileHelper 2: { 3:4:对文件流进行MD5加密 5:6: public static s.
因工作需要对文件进行是否被修改判断，整理的一段生成文件MD5码的代码：
1: public class FileHelper
2: {

4: /// 对文件流进行MD5加密
5: /// </summary>
6: public static string MD5Stream(Stream stream)
7: {
8: MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
9: md5.ComputeHash(stream);
10: byte[] b = md5.Hash;
11: md5.Clear();
12: StringBuilder sb = new StringBuilder(32);
13: for (int i = 0; i < b.Length; i++)
14: {
15: sb.Append(b[i].ToString("X2"));
16: }
17: return sb.ToString();
18: }
19: /// <summary>
20: /// 对文件进行MD5加密
21: /// </summary>
22: public static string MD5Stream(string filePath)
23: {
24: using (FileStream stream = File.Open(filePath, FileMode.Open))
25: {
26: return MD5Stream(stream);
27: }
28: }
