C#操作证书

　　1、使用C#操作证书：基本思路通过将证书转化为二进制数组，将数组解析为证书格式。使用

using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
命名空间。使用

X509Certificate2 x509 = new X509Certificate2();类
可以参考MSDN：    http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509certificate2.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-1
