範例

下列範例示範 Remove 方法的用法。

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("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.");
      }
   }
}

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

備註

這個方法會執行線性搜尋;因此，平均執行時間與 成正比 Count 。

移除 MessagePart 後的元素會向上移動，以佔用空空的地點。
