答案 0 :(得分：1)
在EndpointIdentity上设置证书的位置会导致它用于验证服务的身份。您尚未使用instance.ClientCredentials.ClientCertificate.SetCertificate(...)设置客户端的凭据。您必须从ClientBase＆lt;＆gt;获取ClientCredentials使用反射。请参阅http://msdn.microsoft.com/en-us/library/ms732391%28v=vs.110%29.aspx。
var credentialProperty = instance.GetType().GetProperty("ClientCredentials");
var credentials = (ClientCredentials)credentialProperty.GetValue(instance, null);
credentials.ClientCertificate.SetCertficate(...);
您还有两次拨打EndpointIdentity.CreateX509CertificateIdentity，忽略了其中一个的输出。
