Exemplos

O exemplo de código a seguir demonstra cenários em que ArrayTypeMismatchException é gerado.

   array<String^>^names = { "Dog", "Cat", "Fish"};
   array<Object^>^objs = dynamic_cast<array<Object^>^>(names);
   try
   {

      for ( Int32 i = 0; i < objs->Length; i++ )
      {
         Console::WriteLine( objs[ i ] );

      }
   }
   catch ( System::ArrayTypeMismatchException^ ) 
   {
      
      // Not reached, "Mouse" is of the correct type
      Console::WriteLine(  "Exception Thrown" );
   }

   try
   {

      objs[ 2 ] = obj;
   }
   catch ( System::ArrayTypeMismatchException^ ) 
   {
      
      // Always reached, 13 is not a string.

Comentários

ArrayTypeMismatchException é gerado quando o sistema não pode converter o elemento no tipo declarado para a matriz. Por exemplo, um elemento do tipo String não pode ser armazenado em uma Int32 matriz porque não há suporte para a conversão entre esses tipos. Geralmente, é desnecessário que os aplicativos lancem essa exceção.

As seguintes instruções msil (linguagem intermediária da Microsoft) lançam ArrayTypeMismatchException:

• ldelem.<type>

• ldelema

• stelem.<type>

ArrayTypeMismatchException usa o COR_E_ARRAYTYPEMISMATCH HRESULT, que tem o valor 0x80131503.
