來自CodeBehind的Silverlight自定義綁定

Question

我已經看到了許多有關WShttpbinding和Silverlight的示例。 另外，我成功地運行了該應用程序，但必須從后面的代碼創建自定義綁定。

我已經嘗試過了，但是出現如下錯誤：

In Binding 'MyCustom', TransportBindingElement 'HttpsTransportBindingElement' does not
appear last in the BindingElementCollection.  Please change the order of elements such
that the TransportBindingElement is last.

碼

public static MyTempService.ServiceClient WCFServiceClient()
{
    {       
        EndpointAddressBuilder AddressBuilder = new EndpointAddressBuilder(new EndpointAddress("https://node94.MyWab.local:8089/WcfService/Service.svc"));      

        CustomBinding Cusbinding = new CustomBinding
        ("MyCustom",
         "MyTempService",
         SecurityBindingElement.CreateUserNameOverTransportBindingElement(),
         new BinaryMessageEncodingBindingElement(),
         new HttpsTransportBindingElement()
        );

        Cusbinding.Elements.Add(new TextMessageEncodingBindingElement()
        {
            MessageVersion = System.ServiceModel.Channels.MessageVersion.Default,
            WriteEncoding = System.Text.Encoding.UTF8
        });

        Cusbinding.OpenTimeout = new TimeSpan(0, 5, 0);
        Cusbinding.CloseTimeout = new TimeSpan(0, 5, 0);
        Cusbinding.ReceiveTimeout = new TimeSpan(0, 5, 0);
        Cusbinding.SendTimeout = new TimeSpan(0, 5, 0);

        return new MyTempService.ServiceClient(Cusbinding, AddressBuilder.ToEndpointAddress());
    }
}

Answer 1

當我查看您的代碼時，我看到BindingElementCollection中的最后一個是

TextMessageEncodingBindingElement（）

按照以下方式嘗試：

1）從構造器中刪除新的HttpsTransportBindingElement（）

2）將此元素添加為之后的最后一個元素

    Cusbinding.Elements.Add(new TextMessageEncodingBindingElement()
    {
        MessageVersion = System.ServiceModel.Channels.MessageVersion.Default,
        WriteEncoding = System.Text.Encoding.UTF8
    });

    Cusbinding.Elements.Add(new HttpsTransportBindingElement());
