ArrayTypeMismatchException is thrown when the system cannot convert the element to the type declared for the array. For example, an element of type String cannot be stored in an Int32 array because conversion between these types is not supported. It is generally unnecessary for applications to throw this exception.

The following Microsoft intermediate language (MSIL) instructions throw ArrayTypeMismatchException :

  • ldelem.<type>

  • ldelema

  • stelem.<type>

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

For a list of initial property values for an instance of ArrayTypeMismatchException, see the ArrayTypeMismatchException constructors.

The following code example demonstrates scenarios where ArrayTypeMismatchException is thrown.

using namespace System;
int main()
{
   array<String^>^names = { "Dog", "Cat", "Fish"};
   array<Object^>^objs = dynamic_cast<array<Object^>^>(names);
   try
   {
      objs[ 2 ] = (Object^)"Mouse";
      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
   {
      Object^ obj = 13;
      objs[ 2 ] = obj;
   }
   catch ( System::ArrayTypeMismatchException^ ) 
   {

      // Always reached, 13 is not a string.
      Console::WriteLine(  "New element is not of the correct type" );
   }


   // Set obj to an array of objects instead of an array of strings 
   array<Object^>^objs2 = gcnew array<Object^>(3);
   try
   {
      objs2[ 0 ] = (Object^)"Turtle";
      objs2[ 1 ] = 12;
      objs2[ 2 ] = 2.341;
      for ( Int32 i = 0; i < objs->Length; i++ )
      {
         Console::WriteLine( objs2[ i ] );

      }
   }
   catch ( System::ArrayTypeMismatchException^ ) 
   {

      // ArrayTypeMismatchException is not thrown this time.
      Console::WriteLine(  "Exception Thrown" );
   }

}
