C＃：如何在使用X509身份验证证书的WCF服务上解决System.FormatException

Question

我正面临着我难以理解的问题。我尝试做的是创建WCF服务。在此服务上，我尝试在服务器和客户端使用证书进行身份验证。这是我的代码和例外列表。

  

System.FormatException：Base-64 char数组的长度无效或   串。在System.Convert.FromBase64_Decode（Char * startInputPtr，   Int32 inputLength，Byte * startDestPtr，Int32 destLength）at   System.Convert.FromBase64CharPtr（Char * inputPtr，Int32 inputLength）
  在System.Convert.FromBase64String（String s）at   System.ServiceModel.Description.ConfigLoader.LoadIdentity（IdentityElement   元素）   System.ServiceModel.Description.ConfigLoader.LoadServiceDescription（ServiceHostBase   host，ServiceDescription描述，ServiceElement serviceElement，   Action`1 addBaseAddress，Boolean skipHost）at   System.ServiceModel.ServiceHostBase.LoadConfigurationSectionInternal（ConfigLoader   configLoader，ServiceDescription描述，ServiceElement   serviceSection）at   System.ServiceModel.ServiceHostBase.ApplyConfiguration（）at   System.ServiceModel.ServiceHost.ApplyConfiguration（）at   System.ServiceModel.ServiceHostBase.InitializeDescription（UriSchemeKeyedCollection   baseAddresses）at   System.ServiceModel.ServiceHost.InitializeDescription（类型   serviceType，UriSchemeKeyedCollection baseAddresses）at   System.ServiceModel.ServiceHost..ctor（类型serviceType，Uri []   baseAddresses）at   Microsoft.Tools.SvcHost.ServiceHostHelper.CreateServiceHost（Type type，   ServiceKind亲切）   Microsoft.Tools.SvcHost.ServiceHostHelper.OpenService（ServiceInfo   信息）

namespace Test
{
    [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]

    class TestService:ITestUser
    {
        public string Print(string text)
        {
            return "You've printed: " + text;
        }
    }
}

namespace Test
{
    [DataContract]
    public class TestUser 
    {
        [DataMember]
        string Username;
        [DataMember]
        string Password;
    }
}

namespace Test
{
    [ServiceContract]
    public interface ITestUser
    {
        [OperationContract]
        string Print(string text);
        [OperationContract]
        bool Authorise(string Username, string Password);
    }
}
