推荐答案

您可以使用我的函数检查端口是否可用:

You can use my function to check, if a port is available:

function CheckPortOccupied(Port:String):Boolean;
var
  ResultCode: Integer;
begin
  Exec(ExpandConstant('{cmd}'), '/C netstat -na | findstr'+' /C:":'+Port+' "', '', 0,
       ewWaitUntilTerminated, ResultCode);
  if ResultCode <> 1 then
  begin
    Log('this port('+Port+') is occupied');
    Result := True;
  end
    else
  begin
    Result := False;
  end;
end;
