備註

ArrayTypeMismatchException 當系統無法將專案轉換成為陣列宣告的類型時,就會擲回 。 例如,型 String 別的元素無法儲存在陣列中 Int32 ,因為不支援這些類型之間的轉換。 應用程式通常不需要擲回此例外狀況。

下列 Microsoft 中繼語言 (MSIL) 指示擲回 ArrayTypeMismatchException

  • ldelem.<type>

  • ldelema

  • stelem.<type>

ArrayTypeMismatchException 會使用 HRESULT COR_E_ARRAYTYPEMISMATCH,其值為 0x80131503。
