然后在Cert类中写一个Read方法读取其中的证书。注意：pfx文件有可能包含几个证书

11    public class Cert
12    {
13        public Cert()
14        {
15            //
16            // TODO: 在此处添加构造函数逻辑

19        public static System.Security.Cryptography.X509Certificates.X509Certificate[] Read(string filename,string password) {
20
21            //打开证书文件，并读到一个字节数组中。
22            FileStream stream = new FileStream(filename,FileMode.Open);
23            byte[] buffer = new byte[stream.Length];
24            stream.Read(buffer,0,buffer.Length);
25            stream.Close();
