如何使用Delphi将字节数组转换为字符串? [英] How do I convert an array of bytes to string with Delphi?

问题描述

我正在用Delphi开发一个项目，我想将字节数组转换为字符串类型.我该怎么办?

I am developing a project with Delphi and I want to convert the byte array to string type. How can I do?

示例C#代码:

private void ListenerOnDataTransmit(DataTransmitEventArgs e)
{
    transmittedMsg = BitConverter.ToString(e.TransmittedBytes, 0, e.TransmittedBytes.Length);
    try { Invoke(new EventHandler(UpdateTransmittedMessagesListView)); }
    catch { }
}

推荐答案

SysUtils.IntToHex()函数在Delphi 7中手动执行相同的操作，例如:

The BitConverter.ToString() method "Converts the numeric value of each element of a specified array of bytes to its equivalent hexadecimal string representation." You can do the same thing manually in Delphi 7 by using the SysUtils.IntToHex() function in a loop, eg:

uses
  ..., SysUtils;

var
  bytes: array of byte;
  s: string;
  i: Integer;
begin
  bytes := ...;
  s := '';
  if bytes <> nil then
  begin
    s := IntToHex(bytes[0], 2);
    for i := 1 to High(bytes) do
      s := s + '-' + IntToHex(bytes[i], 2);
  end;
end;
