我問,因爲它連接到我的本地開發數據庫我的單元測試都使用的GUID沒有問題,但是當我使用通過我的WCF服務的相同方法,它失敗,出現以下異常:WCF可以處理GUID嗎?
System.Data.EntityCommandExecutionException
我已經閱讀WCF將Guid轉換爲字符串。我確切的情況是這樣的:
代理 - >通帶的Guid
服務<對象 - 連接到數據庫,插入/檢索事情瓦特/的Guid
服務 - > GUID爲傳遞對象返回給代理
以下是錯誤從Web應用程序測試的WCF服務時:

這裏是從跟蹤的內部異常Viewer:

異常類型意味着這是一個與數據相關的異常。你能發佈完整的異常(消息,鍵入+堆棧跟蹤)嗎? –
我不確定GUID數據類型是否可互操作。你試過用一個字符串代替嗎? –
「EntityCommandExecutionException」的內部異常是什麼? – svick
