	MessagePart^ messagePart
)

Parameters

Return Value

A 32-bit signed integer.

The following example demonstrates a use of the IndexOf method to determine whether a specified MessagePart is a member of the collection.

Console::WriteLine( "Checking if message is AddHttpPostOut..." );
Message^ myMessage = myServiceDescription->Messages[ "AddHttpPostOut" ];
if ( myMessageCollection->Contains( myMessage ) )
{
   // Get the mssage part collection.
   MessagePartCollection^ myMessagePartCollection = myMessage->Parts;

   // Get the part named Body.
   MessagePart^ myMessagePart = myMessage->Parts[ "Body" ];
   if ( myMessagePartCollection->Contains( myMessagePart ) )
   {
      // Get the part named Body.
      Console::WriteLine( "Index of Body in MessagePart collection = {0}", myMessagePartCollection->IndexOf( myMessagePart ) );
      Console::WriteLine( "Deleting Body from MessagePart collection..." );
      myMessagePartCollection->Remove( myMessagePart );
      if ( myMessagePartCollection->IndexOf( myMessagePart ) == -1 )
               Console::WriteLine( "from the message AddHttpPostOut." );
   }
}
Console::WriteLine(S"Checking if message is AddHttpPostOut...");
Message* myMessage = myServiceDescription->Messages->Item[S"AddHttpPostOut"];
if (myMessageCollection->Contains(myMessage)) 
{
   // Get the mssage part collection.
   MessagePartCollection* myMessagePartCollection = myMessage->Parts;
   // Get the part named Body.
   MessagePart* myMessagePart = myMessage->Parts->Item[S"Body"];
   if (myMessagePartCollection->Contains(myMessagePart)) 
   {
      // Get the part named Body.
      Console::WriteLine(S"Index of Body in MessagePart collection = {0}",
         __box( myMessagePartCollection->IndexOf(myMessagePart)));
      Console::WriteLine(S"Deleting Body from MessagePart collection...");
      myMessagePartCollection->Remove(myMessagePart);
      if (myMessagePartCollection->IndexOf(myMessagePart)== -1) 
         Console::WriteLine(S"MessagePart Body successfully deleted "\
            S"from the message AddHttpPostOut.");
   }
}
