窺視，合併多個IQueryables在一起 - Silverlight的
我是個重生的處女Silverlight的，所以請大家多多包涵。我有兩個單獨的DomainServices，指向兩個不同的SQL數據庫服務器。在這些域服務中，我已經在每個域服務中設置了一些IQueryables。
我需要將兩個IQueryables從單獨的DomainServices合併在一起。我確定這一定是可以做到的。
以下是兩個域服務。
我想將GetCustomCallLogs（來自HEATLiveDomainService）和GetTblCallsLogged（來自HeatDomainService）合併在一起。 GetCustomCallLogs中的關鍵字是CallID，GetTblCallsLogged中的關鍵字是RecID。
如果有可能我明白我需要創建一個新類型來考慮來自兩個連接表中的任何字段。
希望我的情景解釋了我的情景，我不是愚蠢的。
在此先感謝

注意事項： 不能有鏈接的服務器，這樣做時，在源（SQL Server）的是出了問題。 無法創建SP並使用OpenQuery（以及我可以但我想學會正確地做到這一點），因爲我確定這不是正確的做法。
