如何将从Windows服务程序调用的证书与网络服务帐户一起使用？

X509Certificate2 certificate = new X509Certificate2("CertName", StoreLocation.LocalMachine);

string serviceName = "MyService";
string accountName = ServiceProcess.ServiceAccount.NetworkService.ToString();

ServiceController sc = new ServiceController(serviceName);
sc.Refresh();

WindowsIdentity identity = new WindowsIdentity(accountName);
WindowsImpersonationContext context = identity.Impersonate();

// 在这里执行需要使用证书的操作

context.Undo();
