示例

下面的示例演示如何使用从零开始的索引来检索成员 MimePartCollection。

MimeMultipartRelatedBinding^ myMimeMultipartRelatedBinding = nullptr;
IEnumerator^ myIEnumerator = myOutputBinding->Extensions->GetEnumerator();
while ( myIEnumerator->MoveNext() )
   myMimeMultipartRelatedBinding = (MimeMultipartRelatedBinding^)myIEnumerator->Current;

MimePartCollection^ myMimePartCollection = gcnew MimePartCollection;
myMimePartCollection = myMimeMultipartRelatedBinding->Parts;
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 ] );
MimePart^ myMimePart1 = gcnew MimePart;

// Create an instance of 'MimeXmlBinding'.
MimeXmlBinding^ myMimeXmlBinding1 = gcnew MimeXmlBinding;
myMimeXmlBinding1->Part = "body";
myMimePart1->Extensions->Add( myMimeXmlBinding1 );

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

// Check whether 'Insert' was successful or not.
if ( myMimePartCollection->Contains( myMimePart1 ) )
