我能夠連接到數據庫,但是當我嘗試插入我得到這個神祕的錯誤:MySQL的插入導致了個MySqlException上.ExecuteNonQuery
已發生錯誤0:命令執行過程中遇到致命錯誤。
我檢查過,我的所有參數都有值,它們與列標題完全匹配,除了自動增量的ID。
我要問哪裏錯了?

副本的SQL代碼爲字符串,並嘗試直接在我的SQL Server – Jackson
上執行它是否真的有*有關異常沒有*其他信息?您似乎在扔掉潛在的有用信息,例如堆棧跟蹤或任何潛在的內部異常或「MySqlException」中的任何其他屬性。不要扔掉有關錯誤的信息。 – David
參數名稱中是否允許使用圓括號?即使它們是*無與倫比的*括號允許? (請參閱參數39)嘗試不使用所有這些括號,也許這些是數據庫的語法錯誤。 – David
