Esempi

Nell'esempio seguente viene illustrato un utilizzo tipico del IndexOf metodo.The following example demonstrates a typical use of the IndexOf method.

Console::WriteLine( "Total number of mimepart elements in the collection initially  is: {0}", myMimePartCollection->Count );

// Get the type of first 'Item' in collection.
Console::WriteLine( "The first object in collection is of type: {0}", myMimePartCollection[ 0 ] );

//  a mimepart at first position.
myMimePartCollection->Insert( 0, myMimePart1 );
Console::WriteLine( "Inserting a mimepart object..." );
