WCF BehaviorExtensionElement SVCEditor中的嵌套属性

Question

我为自定义Message创建了CustomBehaviorExtensionElement和CustomEndpointBehavior。

public class CustomEndpointBehavior : IEndpointBehavior
{
    private X509Certificate2 certificate;
    public X509Certificate2 Certificate { get => certificate; set => certificate = value; }

    public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {

    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    {
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }
}
public class CustomBehaviorExtensionElement : BehaviorExtensionElement
{
    private ConfigurationPropertyCollection properties;

    [ConfigurationProperty("Certificate")]
    public X509CertificateConfigurationElement Certificate
    {
        get
        {
            return (X509CertificateConfigurationElement)base["Certificate"];
        }
    }
    protected override ConfigurationPropertyCollection Properties
    {
        get
        {
            if (this.properties == null)
            {
                this.properties = new ConfigurationPropertyCollection
                {
                    new ConfigurationProperty("Certificate", typeof(X509CertificateConfigurationElement), null, null, null, ConfigurationPropertyOptions.None),
                };
            }
            return this.properties;
        }
    }

    public override Type BehaviorType
    {
        get { return typeof(CustomEndpointBehavior); }
    }

    protected override object CreateBehavior()
    {
        // Create the  endpoint behavior that will insert the message  
        // inspector into the client runtime  
        return new CustomEndpointBehavior();
    }
}
public class X509CertificateConfigurationElement : ConfigurationElement
{
    private ConfigurationPropertyCollection properties;
    protected override ConfigurationPropertyCollection Properties
    {
        get
        {
            if (this.properties == null)
            {
                this.properties = new ConfigurationPropertyCollection
                {
                    new ConfigurationProperty("findValue", typeof(string), string.Empty, null, new StringValidator(0, 2147483647, null), ConfigurationPropertyOptions.None),
                    new ConfigurationProperty("storeLocation", typeof(StoreLocation), StoreLocation.CurrentUser, null, null, ConfigurationPropertyOptions.None),
                    new ConfigurationProperty("storeName", typeof(StoreName), StoreName.My, null, null, ConfigurationPropertyOptions.None),
                    new ConfigurationProperty("x509FindType", typeof(X509FindType), X509FindType.FindBySubjectDistinguishedName, null, null, ConfigurationPropertyOptions.None)
                };
            }
            return this.properties;
        }
    }

    [ConfigurationProperty("findValue", DefaultValue = ""), StringValidator(MinLength = 0)]
    public string FindValue
    {
        get
        {
            return (string)base["findValue"];
        }
        set
        {
            if (string.IsNullOrEmpty(value))
            {
                value = string.Empty;
            }
            base["findValue"] = value;
        }
    }

    [ConfigurationProperty("storeLocation", DefaultValue = StoreLocation.CurrentUser)]
    public StoreLocation StoreLocation
    {
        get
        {
            return (StoreLocation)base["storeLocation"];
        }
        set
        {
            base["storeLocation"] = value;
        }
    }

    [ConfigurationProperty("storeName", DefaultValue = StoreName.My)]
    public StoreName StoreName
    {
        get
        {
            return (StoreName)base["storeName"];
        }
        set
        {
            base["storeName"] = value;
        }
    }

    [ConfigurationProperty("x509FindType", DefaultValue = X509FindType.FindBySubjectDistinguishedName)]
    public X509FindType X509FindType
    {
        get
        {
            return (X509FindType)base["x509FindType"];
        }
        set
        {
            base["x509FindType"] = value;
        }
    }
}

但在SVCEditor中，我没有看到类X509CertificateConfigurationElement的嵌套属性。 SVCEditor只显示Type name，但我期望嵌套属性findValue，storeLocation，storeName，x509FindType。 Example here 我做错了什么？谢谢你的回答。

我用TypeConverter类解决问题。我创建了自定义TypeConverter

public class X509CertificateConverter : ExpandableObjectConverter
{
    public override object ConvertTo(ITypeDescriptorContext context,
                         System.Globalization.CultureInfo culture,
                         object value, Type destType)
    {
        if (destType == typeof(string) && value is X509CertificateConfigurationElement)
        {
            X509CertificateConfigurationElement cert = (X509CertificateConfigurationElement)value;
            return "Certificate";
        }
        return base.ConvertTo(context, culture, value, destType);
    }
    public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes)
    {
        if (value is X509CertificateConfigurationElement)
        {
            X509CertificateConfigurationElement cert = (X509CertificateConfigurationElement)value;

            PropertyDescriptorCollection allProps = TypeDescriptor.GetProperties(cert);

            PropertyDescriptor[] propertyDescriptor = new PropertyDescriptor[4];
            propertyDescriptor[0] = allProps["FindValue"];
            propertyDescriptor[1] = allProps["StoreLocation"];
            propertyDescriptor[2] = allProps["StoreName"];
            propertyDescriptor[3] = allProps["X509FindType"];

            return new PropertyDescriptorCollection(propertyDescriptor);
        }
        return base.GetProperties(context, value, attributes);
    }
}

在ConfigurationElement上使用它

[TypeConverter(typeof(X509CertificateConverter))]
public class X509CertificateConfigurationElement : ConfigurationElement
{
    private ConfigurationPropertyCollection properties;
    protected override ConfigurationPropertyCollection Properties
    {
        get
        {
            if (this.properties == null)
            {
                this.properties = new ConfigurationPropertyCollection
                {
                    new ConfigurationProperty("findValue", typeof(string), string.Empty, null, new StringValidator(0, 2147483647, null), ConfigurationPropertyOptions.None),
                    new ConfigurationProperty("storeLocation", typeof(StoreLocation), StoreLocation.CurrentUser, null, null, ConfigurationPropertyOptions.None),
                    new ConfigurationProperty("storeName", typeof(StoreName), StoreName.My, null, null, ConfigurationPropertyOptions.None),
                    new ConfigurationProperty("x509FindType", typeof(X509FindType), X509FindType.FindBySubjectDistinguishedName, null, null, ConfigurationPropertyOptions.None)
                };
            }
            return this.properties;
        }
    }

    [ConfigurationProperty("findValue", DefaultValue = ""), StringValidator(MinLength = 0)]
    public string FindValue
    {
        get
        {
            return (string)base["findValue"];
        }
        set
        {
            if (string.IsNullOrEmpty(value))
            {
                value = string.Empty;
            }
            base["findValue"] = value;
        }
    }

    [ConfigurationProperty("storeLocation", DefaultValue = StoreLocation.CurrentUser)]
    public StoreLocation StoreLocation
    {
        get
        {
            return (StoreLocation)base["storeLocation"];
        }
        set
        {
            base["storeLocation"] = value;
        }
    }

    [ConfigurationProperty("storeName", DefaultValue = StoreName.My)]
    public StoreName StoreName
    {
        get
        {
            return (StoreName)base["storeName"];
        }
        set
        {
            base["storeName"] = value;
        }
    }

    [ConfigurationProperty("x509FindType", DefaultValue = X509FindType.FindBySubjectDistinguishedName)]
    public X509FindType X509FindType
    {
        get
        {
            return (X509FindType)base["x509FindType"];
        }
        set
        {
            base["x509FindType"] = value;
        }
    }
}
