建立自己的 MVC portal (二）
为了更好的建立自己的MVC Portal我们首先要做些准备，这些准备就是建立自己的一些常用类库，将自己将要使用的技术进行有效的管理和准备。
首先我们要建立一个类工程：VonLibrary，在这里面我们将实现常用数据管理的基类，加密和摘要机制，以及Json转换等基础类。
首先建立一个VonLibrary工程文件：
添加第一个文件，Crypto.cs
using System.IO;
using System.Text;
using System.Security.Cryptography;
namespace VonPortal.Library
{
public static class Crypto
{
const string B64Chars = "6XutUOdSRPYpQ5ev1@mhgx7r3DiGk0BnM24a8FLAVlIyjZqf%E9CKzHWcwboGsNT%MmCBNyx1bUP5SZWtI0qrd@sDpoHnu8LT3Re9lkF24EiAvYVfgj7ac6GKzXGQOwhjmCS3bGPI0sXTVFy%8ezk9aAcqnZtDlNKUYwWHiLruMG5xf4@1g2QE7R6opOvdhBfI6X@vP3qikhFgdMmbNOS9Rr%jUsLlDuG7We4ywCEoapYZVHT0xKBc1G5t8AnQ2z";
public static string MD5File(string filename)
{
FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read);
MD5CryptoServiceProvider MD5 = new MD5CryptoServiceProvider();
byte[] md5byte = MD5.ComputeHash(fs);
string str = "";
foreach (byte b in md5byte)
{
str += B64Chars[b];
}
fs.Close();
return str;
}
public static string MD5String(string text)
{
byte[] byts = Encoding.UTF8.GetBytes(text);
MD5CryptoServiceProvider MD5 = new MD5CryptoServiceProvider();
byte[] md5byte = MD5.ComputeHash(byts);
string str = "";
foreach (byte b in md5byte)
{
str += B64Chars[b];
}
return str;
}
}
}
