如何通过 WSHttpBinding 安全性和 GZip 压缩来构建自定义绑定？

我在这里面临一个问题。我正在做一个客户端/服务器项目，这是 WCF Web 服务调用来获取数据。由于传输的数据量很大，我必须以编程方式将绑定更改为自定义绑定（而不是通过配置文件）。

我正在创建一个新用户-定义绑定又称为自定义绑定。该类的示例是：

public class MyCustomBinding : CustomBinding

并覆盖函数 BindingElementCollection：

public override BindingElementCollection CreateBindingElements()
{
   WSHttpBinding wSHttpBinding = new WSHttpBinding("RMSKeberosBinding"); //this is to load the configuration from app.config. because i want to copy the setting of wsHttpConfig to my custom binding.

   BindingElementCollection wSHttpBindingElementCollection = wSHttpBinding.CreateBindingElements();

   TransactionFlowBindingElement transactionFlowBindingElement = wSHttpBindingElementCollection.Remove&lt;TransactionFlowBindingElement&gt;();
   SymmetricSecurityBindingElement securityElement = wSHttpBindingElementCollection.Remove&lt;SymmetricSecurityBindingElement&gt;();
   MessageEncodingBindingElement textElement = wSHttpBindingElementCollection.Remove&lt;MessageEncodingBindingElement&gt;();
   HttpTransportBindingElement transportElement = wSHttpBindingElementCollection.Remove&lt;HttpTransportBindingElement&gt;();

   GZipMessageEncodingBindingElement gzipElement = new GZipMessageEncodingBindingElement(); // this is from microsoft sample. i want to add gzip as a compress to my message.

   BindingElementCollection newCol = new BindingElementCollection();
   newCol.Add(transactionFlowBindingElement);
   newCol.Add(securityElement);
   newCol.Add(gzipElement);
   newCo .Add(transElement);
   return newCol;
}

我想做的是从 wshttpbinding 复制所有设置，并添加 gzip 作为消息编码器。 压缩加密数据会导致原始数据大小更大。 这是因为 WSHttpBinding 中的 SymmetricSecurityBindingElement 进行了加密。如何以正确的方式做到这一点？我希望 wshttpbinding 的安全设置以及 gzip 能够正常工作。

i am facing a problem here.
I am doing a client/server project, which is WCF web service calling to get data.Due to huge data of transfering, i got to change my binding to custom binding programmatically(not by config file.)

I am creating a new user-define binding aka custom binding.
example of the class is :

public class MyCustomBinding : CustomBinding

and override a function BindingElementCollection:

public override BindingElementCollection CreateBindingElements()
{
   WSHttpBinding wSHttpBinding = new WSHttpBinding("RMSKeberosBinding"); //this is to load the configuration from app.config. because i want to copy the setting of wsHttpConfig to my custom binding.

   BindingElementCollection wSHttpBindingElementCollection = wSHttpBinding.CreateBindingElements();

   TransactionFlowBindingElement transactionFlowBindingElement = wSHttpBindingElementCollection.Remove<TransactionFlowBindingElement>();
   SymmetricSecurityBindingElement securityElement = wSHttpBindingElementCollection.Remove<SymmetricSecurityBindingElement>();
   MessageEncodingBindingElement textElement = wSHttpBindingElementCollection.Remove<MessageEncodingBindingElement>();
   HttpTransportBindingElement transportElement = wSHttpBindingElementCollection.Remove<HttpTransportBindingElement>();

   GZipMessageEncodingBindingElement gzipElement = new GZipMessageEncodingBindingElement(); // this is from microsoft sample. i want to add gzip as a compress to my message.

   BindingElementCollection newCol = new BindingElementCollection();
   newCol.Add(transactionFlowBindingElement);
   newCol.Add(securityElement);
   newCol.Add(gzipElement);
   newCo .Add(transElement);
   return newCol;
}

what i am trying to do is copy all setting from wshttpbinding, and add on gzip as the message encoder.
Compress an encrypted data will lead to a bigger size of the original data size.
this is because the SymmetricSecurityBindingElement from WSHttpBinding did the encryption.
How to do this in correct way? i want the security setting from wshttpbinding, and also the gzip to work.
