如何在 Metro 风格应用上设置 CertificateValidationMode？

Question

我在 Azure 上有 WCF 自托管服务。我正在尝试制作桌面客户端和 Metro 风格的 App 客户端。我正在使用带有传输安全性和自签名证书的 nettcpbinding。

在 Windows 7 上，此代码有效：

client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
client.GetUpdate(...);

但在 Metro 应用程序上，ServiceCertificate 字段不存在，所以我得到了（预期的）异常

The X.509 certificate CN=SPDEV-1-PC chain building failed.
The certificate that was used has a trust chain that cannot be verified. 
Replace the certificate or change the certificateValidationMode. 
A certificate chain processed, but terminated in a root certificate 
which is not trusted by the trust provider.

如何更改 certificateValidationMode ？

Answer 1

我遇到了类似的问题，我通过反思解决了它。试试看。像这样：

Type credType = typeof (ClientCredential); //enter here type of your credentials
PropertyInfo credPropInfo1 = credType.GetTypeInfo().GetDeclaredProperty("ServiceCertificate");
PropertyInfo credPropInfo2 = credPropInfo1.GetType().GetTypeInfo().GetDeclaredProperty("Authentication");
PropertyInfo credPropInfo3 = credPropInfo2.GetType().GetTypeInfo().GetDeclaredProperty("CertificateValidationMode");
credPropInfo3.SetValue(yourObject, 0); // use the int value of the enum, suggested 0 for None

更新： 这里有一些愚蠢的代码，对我来说运行良好；）

var test6 = client.ClientCredentials.GetType().GetTypeInfo().GetDeclaredProperty("ServiceCertificate").GetValue(client.ClientCredentials);
var test7 = test6.GetType().GetTypeInfo().GetDeclaredProperty("Authentication").GetValue(test6);
test7.GetType().GetTypeInfo().GetDeclaredField("certificateValidationMode").SetValue(test7, 0);
test6.GetType().GetTypeInfo().GetDeclaredField("authentication").SetValue(test6, test7);
client.ClientCredentials.GetType().GetTypeInfo().GetDeclaredField("serviceCertificate").SetValue(client, test6);
