Question

我有以下代码：

namespace SSS.RemoteTruckService
{
  public partial class Startup : Form
  {
    private Timer _gpsTimer;
    private Timer _ppsTimer;
    private Timer _creditCardTimer;
    private Timer _iniTimer;

    public string Message
    {
      get { return richTextBox_Message.Text; }
      set
      {
        richTextBox_Message.Invoke((MethodInvoker)(() 
          => richTextBox_Message.Text = DateTime.Now + " " + 
          value + Environment.NewLine + richTextBox_Message.Text));
      }
    }

    public Startup()
    {
      InitializeComponent();
    }

    private void ButtonStartClick(object sender, EventArgs e)
    {
      StartRemoteTruck();
    }

    private void ButtonPauseClick(object sender, EventArgs e)
    {
      if (_gpsTimer.Enabled) _gpsTimer.Enabled = false;
      if (_ppsTimer.Enabled) _ppsTimer.Enabled = false;
      if (_creditCardTimer.Enabled) _creditCardTimer.Enabled = false;
      if (_iniTimer.Enabled) _iniTimer.Enabled = false;
      ProcessIniFile.StopProcess();
    }

    public void StartRemoteTruck()
    {
      Message = "RemoteTruck started.";

      if (Settings.GlobalSettings == null)
      {
        Message = "GlobalSettings was null or not loaded. Cannot continue.";
        Logging.Log("GlobalSettings was null or not loaded. Cannot continue.", "RemoteTruck", Apps.RemoteTruckService);
        Environment.Exit(0);
      }

      if (Settings.GlobalSettings.IniFileWatcherEnabled)
      {
        ProcessIniFile.StartProcess();        
      }

      CreateTimers();      
    }

在ProcessIniFile.StartProcess()我有代码：

namespace SSS.RemoteTruckService.inifile
{
  public static class ProcessIniFile
  {
    private static DateTime _iniLastWriteTime;
    private static readonly string Inifile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Windows), "sss.ini");
    private static FileSystemWatcher _watcher;

    public static void StartProcess()
    {  
      ReadIniFile();
      SaveCurrentIniReadings();
      CreateIniFileWatcher();
    }

    public static void StopProcess()
    {
      if (_watcher != null)
      {
        _watcher.EnableRaisingEvents = false;
        _watcher = null;
      }
    }

    private static void CreateIniFileWatcher()
    {
       _watcher = new FileSystemWatcher
        {
          Path = Environment.GetFolderPath(Environment.SpecialFolder.Windows),
          NotifyFilter = NotifyFilters.LastWrite,
          Filter = "sss.ini"
        };
      _watcher.Changed += SssIniWatcherChanged;
      _watcher.EnableRaisingEvents = true;
    }

我想将调用表格传回文件监视器的读取状态。

也许我正在思考这个问题，但如果我想在主表单上添加Message，我该如何处理呢？

Answer 1

您可以使用事件。您的流程可以发送事件，您的表单可以处理它们。更多信息：http://msdn.microsoft.com/en-us/library/awbftdfh.aspx

Answer 2

我喜欢使用的简单但不漂亮的方法是使表单的那部分也是静态的。例如，创建静态变量WriteMessage，并在表单加载或Startup()中，您可以设置它：

WriteMessage = (s) => Message = s;

当然这有一些问题，但这是完成它的快速方法。其中一个问题是，如果您不在UI线程上，则可能需要使用Dispatcher.invoke。
