我一直負責在C#.NET中編寫自定義應用程序,以便將消息從一個隊列移動到另一個隊列,同時保留所有上下文和身份信息與原始消息相同。Websphere MQ - 在.NET中從一個隊列移動到另一個隊列時保留消息上下文和身份
我試圖破譯的在線文檔,並試圖在打開隊列MQC.MQOO_PASS_ALL_CONTEXT和MQOO_SAVE_ALL_CONTEXT每一個組合,並在放電話MQC.MQPMO_PASS_ALL_CONTEXT,都無濟於事。我曾嘗試MQPutMessageOptions.ContextReference設置爲源和 目標隊列兩者,但是我繼續得到例外,無論是MQRC_CONTEXT_HANDLE_ERROR或MQRC_OPTIONS_ERROR,我找不到在線文檔足夠的信息來確定問題。
我使用amqmdnet.dll的運行時版本v2.0.50727 V7.5.0.1。如果有人知道我需要使用正確的開放和/或放置消息選項設置,那麼我將非常感激。謝謝。

這是一個非常簡單的GUI程序來測試類,我也得到了相同的結果:

的GUI簡單的提示輸入用戶名和密碼(通過LDAP調用進行驗證),然後啓用運行btnTest_Click方法的「測試」按鈕。即使我認爲我已經使用了指定的所有打開和獲取消息選項,我仍然得到相同的異常(MQRC_CONTEXT_HANDLE_ERROR)。
我有三重檢查所有的開放,獲取和看跌期權 - 有一些I'n沒有得到關於「上下文」因爲現在我收到的例外是「MQRC_CONTEXT_HANDLE_ERROR」(原因代碼2097。 ) – 2015-04-07 15:53:38
