Açıklamalar

ArrayTypeMismatchException Sistem öğeyi dizi için belirtilen türe dönüştüremediği zaman oluşturulur.ArrayTypeMismatchException is thrown when the system cannot convert the element to the type declared for the array. Örneğin, String Int32 Bu türler arasında dönüştürme desteklenmediğinden, türünde bir öğe bir dizide depolanamaz.For example, an element of type String cannot be stored in an Int32 array because conversion between these types is not supported. Uygulamaların bu özel durumu oluşturması genellikle gereksizdir.It is generally unnecessary for applications to throw this exception.

Aşağıdaki Microsoft ara dil (MSIL) yönergeleri şunu oluşturur ArrayTypeMismatchException :The following Microsoft intermediate language (MSIL) instructions throw ArrayTypeMismatchException :

• ldelek.<type>ldelem.<type>

• ldelemaldelema

• stelem.<type>stelem.<type>

ArrayTypeMismatchException 0x80131503 değerine sahip HRESULT COR_E_ARRAYTYPEMISMATCH kullanır.ArrayTypeMismatchException uses the HRESULT COR_E_ARRAYTYPEMISMATCH, which has the value 0x80131503.
