無法對c＃中的'dtInventory_v10_r1'類型錯誤表達式應用索引

Question

我在c＃中有一些代碼是從vb.net轉換而來的。我在aspx頁面的代碼隱藏頁面上收到此錯誤。一個錯誤的讀取

無法適用索引，以類型的表達式「dtInventory_v10_r1」

，我從Visual Studio接收讀取該然而

參數丟失

錯誤

本文引用的代碼行如下：

objInv = objMan.GetInventoryObject(mInventory_ID, , , true); 

的GetInventoryObject是用VB寫，看起來像這樣

    '-- Load XML into Report object 
    Return LoadInventory_XML(strXML) 

End Function 

的mInventory_ID是一個i​​nt變量，並聲明如下

protected Int32 mInventory_ID = 0; 

我不知道如何解決錯誤我正在嘗試將括號改爲方括號無濟於事。我已經嘗試在函數中爲剩餘的聲明添加額外的逗號，但也產生了相同的錯誤。

是否有什麼可能會導致此錯誤，以及如何解決這個

任何建議，謝謝你在前進

這些都是可選的參數，並應符合以下語法

objInv = objMan.GetInventoryObject(vVIN=mInventory_ID, vIncludeValuations=true); 

被稱爲

基本上你明確地命名參數的默認值，你想重寫。與, ,跳過param實際上是不正確的語法。
