使用例

[Visual Basic, C#, C++] IndexOf メソッドを使用して、指定した MessagePart がコレクションのメンバであるかどうかを確認する例を次に示します。

 
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.");
   }
}
