找不到已安装但已过期的证书？

Question

我的一张证书已经过期了。这使以下代码失败：

 X509Store store = new X509Store(settings.CertificateStore, settings.CertificateLocation);
            store.Open(OpenFlags.ReadOnly);
            X509Certificate2Collection certs = store.Certificates.Find(X509FindType.FindByThumbprint, settings.Thumbprint, true);
            store.Close();

            if (certs.Count > 0)
            {
                LogHandler.Instance.Log(LogLev.Info, $"UseSecureConnection > Location:{settings.CertificateLocation}, Store:{settings.CertificateStore}, Thumbprint:{settings.Thumbprint}");
                _serviceHost.Credentials.ServiceCertificate.SetCertificate(settings.CertificateLocation,
                settings.CertificateStore, X509FindType.FindByThumbprint, settings.Thumbprint);

            }
            else
                throw new Exception("Could not find certificate with thumbprint " + settings.Thumbprint);

这个代码工作得非常好，证书已过期。

即使它过期，我如何获取它？

Answer 1

store.Certificates.Find(X509FindType.FindByThumbprint, settings.Thumbprint, false)

应该这样做。 The last parameter是validOnly。
