csharp 这将从本地Web服务器获取x509证书。我用它来建立从Web应用程序到Web上的API的连接

X509Certificate2 x509 = null;
            var chain = new X509Chain();
            chain.ChainPolicy.RevocationMode = X509RevocationMode.Online;
            x509 = new X509Certificate2(Convert.FromBase64String(sslCert));
            chain.Build(x509);

            var store = new X509Store(StoreLocation.LocalMachine);
            store.Open(OpenFlags.ReadOnly);
            var collection = store.Certificates.Find(X509FindType.FindByApplicationPolicy, "1.3.6.1.5.5.7.3.1", true);
            var handler = new WebRequestHandler();

            var chosenCertificate = collection[0];
            handler.ClientCertificates.Add(chosenCertificate);
