SqlException（0x80131904）：'？'附近語法不正確

我是SQl的新手，我正在使用示例，我想知道是否有人可以幫助我編寫一段代碼。我知道我的問號有一個語法錯誤，但我無法弄清楚它在哪裏或爲什麼會發生這種情況。SqlException（0x80131904）：'？'附近語法不正確

這裏是我的代碼：

您在更新語句結束還有

[UnitRetailCost] = ?, WHERE [CICNumber] = ?

，逗號需要刪除：

[UnitRetailCost] = ? WHERE [CICNumber] = ?

謝謝你的幫助！我刪除了逗號，但語法錯誤仍然存在 –

在這裏涉及什麼樣的對象來執行SQL？我問，因爲SqlClient對象使用命名參數，而不是問號 - https://msdn.microsoft.com/en-us/library/yy6y35y8%28v=vs.110%29.aspx –
