如何在UWP中向HttpRequestMessageProperty添加標頭

Question

我正在將某些代碼從本機C＃項目遷移到Universal Windows項目，並嘗試執行以下操作：

HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();

httpRequestProperty.Headers.Add("X-EBAY-SOA-SECURITY-APPNAME", "APPID");
httpRequestProperty.Headers.Add("X-EBAY-SOA-OPERATION-NAME", "findItemsByKeywords");
httpRequestProperty.Headers.Add("X-EBAY-SOA-GLOBAL-ID", "EBAY-US");

OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;

在C＃本機中，我可以向集合中添加標頭，而在UWP中則是不可能的。 似乎System.ServiceModel.Http版本4.0.1.0中的HttpRequestMessageProperty.Headers僅是Getter ...

UWP中的替代方法是什么？ 如何將標頭添加到集合中？

好吧...

httpRequestProperty.Headers["X-EBAY-SOA-SECURITY-APPNAME"] = "APPID";
httpRequestProperty.Headers["X-EBAY-SOA-OPERATION-NAME"] = "findItemsByKeywords";
httpRequestProperty.Headers["X-EBAY-SOA-GLOBAL-ID"] = "EBAY-US";
