Delphi 将Indy9升级到Indy10

我想用Delphi2007将我的应用程序从Indy9升级到10。 在该线程中，有一个对Indy9 TIdUDPBase.SendBuffer的调用，但由于方法参数不存在，因此不会在Indy10中编译。第三个参数aBuffer是一个var参数，我在Indy10中没有找到任何这样的方法签名。 有其他方法可以调用吗

procedure TSenderThread.Execute;
var
  vTimeData: TTimeDataRecord;
  I: Integer;
  FElapsed: Int64;
  FTimerElappsed,
  vLastTimerElappsed: Int64;
begin
  vTimeData.Size := SizeOf(TTimeDataRecord);
  vTimeData.ClientCount := 1;
  Priority := tpHighest;
  FIdUDPClient := TIdUDPClient.Create(nil);
  FIdUDPClient.BroadcastEnabled := True;
  try
    while not (Terminated or Application.Terminated) do
    begin
      Sleep(1000);
      //Measure Time frame
      vLastTimerElappsed := FTimerElappsed;
      QueryPerformanceCounter(FTimerElappsed);
      FElapsed := ((FTimerElappsed-vLastTimerElappsed)*1000000) div FFrequency;
      vTimeData.TotalTimeFrame := FElapsed;
      if FRunning then
      begin
        FElapsed := ((FTimerElappsed-FStart)*1000000) div FFrequency;
        vTimeData.CurrentMessageTime := FElapsed;
      end
      else
        vTimeData.CurrentMessageTime := 0;
      //Copy Values
      vTimeData.AccumulatedTime := InterlockedExchange(TimeData.AccumulatedTime,0);
      vTimeData.MessageCount := InterlockedExchange(TimeData.MessageCount,0);
      for I := 0 to TimeClassMax do
        vTimeData.TimeClasses[I] := InterlockedExchange(TimeData.TimeClasses[I],0);

       // Calls procedure TIdUDPBase.SendBuffer(AHost: string; const APort: Integer; var ABuffer; const AByteCount: integer);
       // This is changed in Indy10, unable to compile  
      FIdUDPClient.SendBuffer('255.255.255.255', UIPerfPort, vTimeData, TimeData.Size);
    end;
  finally
    FreeAndNil(FIdUDPClient);
  end;
end;

编辑： vTimeData基本上是一个整数数组

  TTimeDataRecord = record
    Size: Integer; //Size of record structure is transfered and compared for safty reasons.
    ClientCount: Integer;
    AccumulatedTime: Integer; //This is the accumulated time busy in microseconds
    CurrentMessageTime: Integer; //This is the time the current message has been processed. If several computers report a high value at the same time it indicates a freeze!
    TotalTimeFrame: Integer; //This is the total time measured in microseconds
    MessageCount: Integer;
    TimeClasses: array [0..TimeClassMax] of Integer;
  end;

您有一个同名的方法

procedure TIdUDPClient.SendBuffer(const AHost: string; const APort: TIdPort;
  const ABuffer: TIdBytes);

它需要一个字节数组，而不是一个非类型化的缓冲区。你的数据是什么样的？您只需要将数据写入字节数组。比如：

var
 Buffer: TIdBytes;
begin
 SetLength(Buffer, YourSizeOfData);
 Move(YourData, Buffer[0], YourSizeOfData);
 FIdUDPClient.SendBuffer('255.255.255.255', UIPerfPort, Buffer);
end;

但正如我所说，这取决于数据的类型。然而，这种方法是可行的

编辑：

现在我可以看到您有一个记录，您有两个选择：

只需将整个记录移动到字节数组

Move(@aRecord, Buffer[0], (6 + TimeClassMax) * SizeOf(Integer));

在您的记录中有一个CopyToBytes方法来进行实际复制。我想更一般

TTimeDataRecord = record
  Size: Integer; //Size of record structure is transfered and compared for safty reasons.
  ClientCount: Integer;
  AccumulatedTime: Integer; //This is the accumulated time busy in microseconds
  CurrentMessageTime: Integer; //This is the time the current message has been  processed. If several computers report a high value at the same time it indicates a freeze!
  TotalTimeFrame: Integer; //This is the total time measured in microseconds
  MessageCount: Integer;
  TimeClasses: array [0..TimeClassMax] of Integer;
  procedure CopyToBytes(var Buffer: TIdBytes);
end

CopyToBytes的实现

procedure TTimeDataRecord.CopyToBytes(var Buffer: TIdBytes);
begin
  // copy the data however you see fit
end;

它是一条记录，请参见更新，但它只包含整数。也许我可以将其类型转换为TIdBytes，或者我必须将其复制到另一个TIdBytes类型的缓冲区？仅供参考，Indy 10具有RawToBytes（）和BytesToRaw（）函数，用于将TIdBytes值从/转换为原始内存块。
