Example

[Visual Basic, C#, C++] The following example demonstrates a use of the IndexOf method to determine whether a specified MessagePart is a member of the collection.

[Visual Basic] 
Console.WriteLine("Checking if message is AddHttpPostOut...")
Dim myMessage As Message = myServiceDescription.Messages("AddHttpPostOut")
If myMessageCollection.Contains(myMessage) Then

   ' Get the message part collection.
   Dim myMessagePartCollection As MessagePartCollection = myMessage.Parts

   ' Get the part named Body.
   Dim myMessagePart As MessagePart = myMessage.Parts("Body")
   If myMessagePartCollection.Contains(myMessagePart) Then

      ' Get the index of the part named Body.
      Console.WriteLine("Index of Body in MessagePart collection = " & _
         myMessagePartCollection.IndexOf(myMessagePart).ToString)
      Console.WriteLine("Deleting Body from MessagePart Collection...")
      myMessagePartCollection.Remove(myMessagePart)
      If myMessagePartCollection.IndexOf(myMessagePart) = -1 Then
         Console.WriteLine("MessagePart Body successfully deleted " & _
         "from the message AddHttpPostOut.")
      End If
   End If
End If

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

   // Get the part named Body.
   MessagePart myMessagePart = myMessage.Parts["Body"];
   if (myMessagePartCollection.Contains(myMessagePart))
   {
      // Get the index of the part named Body.
      Console.WriteLine("Index of Body in MessagePart collection = " + 
         myMessagePartCollection.IndexOf(myMessagePart));
      Console.WriteLine("Deleting Body from MessagePart collection...");
      myMessagePartCollection.Remove(myMessagePart);
      if(myMessagePartCollection.IndexOf(myMessagePart)== -1)
      {
         Console.WriteLine("MessagePart Body successfully deleted " +
            "from the message AddHttpPostOut.");
      }
   }
}

[C++] 
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.");
   }
}
