C#检查证书是否存在

1 X509Store store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
2             store.Open(OpenFlags.MaxAllowed);
3             X509Certificate2Collection certs = store.Certificates.Find(X509FindType.FindBySubjectName, "SRCA", false);
4             if (certs.Count == 0 || certs[0].NotAfter < DateTime.Now)
5             {
6                 Console.WriteLine("需要创建证书");
7             }

安装证书:

 1 using System.Security.Cryptography.X509Certificates;
 2 
 3  
 4 
 5 MessageBox.Show("开始");
 6 
 7  
 8 
 9 //添加个人证书
10 
11 X509Certificate2 certificate = new X509Certificate2(Application.StartupPath + \\cert.pfx","证书密码");
12 X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
13 store.Open(OpenFlags.ReadWrite);
14 store.Remove(certificate);   //可省略
15 store.Add(certificate);
16 store.Close();
17 
18 
19  
20 
21 //安装CA的根证书到受信任根证书颁发机构
22 certificate = new X509Certificate2(Application.StartupPath + "\\CA.cer");
23 store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
24 store.Open(OpenFlags.ReadWrite);
25 store.Remove(certificate);   //可省略
26 store.Add(certificate);
27 store.Close();
28
