在代碼中設置wcf端點標題

Question

在配置中設置端點標題的等效代碼是什麼？

<client> 
<endpoint address="http://localhost/..." > 
<headers> 
<something>blah</something> 
</headers> 
</endpoint> 

Answer 1

這工作：

var header = MessageHeader.CreateHeader("something", "", "blah"); 

using (new OperationContextScope(channel)) 
{ 
    OperationContext.Current.OutgoingMessageHeaders.Add(header); 

    //your normal call here 
} 

Answer 2

不需要創建一個新的OperationContextScope和每次使用客戶端創建EndpointAddress時指定報頭時設置標題中的替代品。

實施例（改編自https://stackoverflow.com/a/5340009/35233）

var binding = new WSHttpBinding(); 
var address = new EndpointAddress (
    new Uri (RemoteAddress), 
    new AddressHeader[] { 
     AddressHeader.CreateAddressHeader ("APIKey", "", "bda11d91-7ade-4da1-855d-24adfe39d174") 
    }); 

var client = new ExampleClient (binding, address);
