C# 在许多其他形式中具有一个控件的功能和属性

如何在许多其他窗体上具有窗体控件的属性和功能。对于一种形式，我喜欢这样：

flashForm flashForm = new flashForm();

public partial class MainUI : Form {
   //...
   public class RequireShowMovieEventArgs : EventArgs {
     public string MoviePath {get; private set;}
     public RequireShowMovieEventArgs(string moviePath){
       MoviePath = moviePath;
     }
   }
   public delegate void RequireShowMovieEventHandler(object sender, RequireShowMovieEventArgs e);
   public static event RequireShowMovieEventHandler RequireShowMovie;
   //...
}
//just fire the event when you want to show/change the movie
RequireShowMovieEventHandler handler = MainUI.RequireShowMovie;
if(handler != null) handler(yourObject, new MainUI.RequireShowMovieEventArgs(@"D:\football scoreboard project\football scoreboard\footballscoreb    \quran.swf"));
//Your display form (which you call flashForm)
public class FlashForm : Form {
 public FlashForm(){
   MainUI.RequireShowMovie += RequiresShowMovieHandler;
   Disposed += (s,e) => {
      MainUI.RequireShowMovie -= RequiresShowMovieHandler;
   };
 }
 private void RequireShowMovieHandler(object sender, MainUI.RequireShowMovieEventArgs e){
   MOVIE = e.MoviePath;
   axShockwaveFlash1.Show();      
 }
 //....
}

对于加载的表单：

        flashForm.SHOW();

点击以下按钮：

  flashForm.MOVIE = @"D:\football scoreboard project\football scoreboard\footballscoreb    \quran.swf";
    flashForm.Controls["axShockwaveFlash1"].Show();

但对于其他形式，我不能使用第一行代码，因为它使该形式的新对象不是我想要的形式

形式之间有大量的通信方式。我猜你的情况是你有一些控制权来加载和播放某种形式的电影。我想介绍这样一种机制，在这种机制中，控件不需要知道显示内容，它只需触发一些事件来通知

我想显示这部电影

，显示表单也不需要在任何类中保持/引用，它只需订阅事件并在触发事件时显示/更改电影。看起来我们需要一些静态事件。您可以在主UI类中定义此静态事件，如下所示：

flashForm flashForm = new flashForm();

public partial class MainUI : Form {
   //...
   public class RequireShowMovieEventArgs : EventArgs {
     public string MoviePath {get; private set;}
     public RequireShowMovieEventArgs(string moviePath){
       MoviePath = moviePath;
     }
   }
   public delegate void RequireShowMovieEventHandler(object sender, RequireShowMovieEventArgs e);
   public static event RequireShowMovieEventHandler RequireShowMovie;
   //...
}
//just fire the event when you want to show/change the movie
RequireShowMovieEventHandler handler = MainUI.RequireShowMovie;
if(handler != null) handler(yourObject, new MainUI.RequireShowMovieEventArgs(@"D:\football scoreboard project\football scoreboard\footballscoreb    \quran.swf"));
//Your display form (which you call flashForm)
public class FlashForm : Form {
 public FlashForm(){
   MainUI.RequireShowMovie += RequiresShowMovieHandler;
   Disposed += (s,e) => {
      MainUI.RequireShowMovie -= RequiresShowMovieHandler;
   };
 }
 private void RequireShowMovieHandler(object sender, MainUI.RequireShowMovieEventArgs e){
   MOVIE = e.MoviePath;
   axShockwaveFlash1.Show();      
 }
 //....
}

---

注意：上面我的代码中的

yourObject

是您想要的，甚至

null

。但是，您应该考虑传递触发事件的实际控件（例如按钮）。

您可能会逃脱<代码> SuntLon < /C> >：

public class MovieForm : Form
{

    private MovieForm _instance;

    private MovieForm()...

    public static MovieForm Instance
    {
        get
        {
            if (_instance == null) _instance = new MovieForm();
            return _instance;
        }
    }

    public void Play()...
    public void Play(Url movieUrl)...
    public void Pause()...
    public void Stop()...
}

用法：

Movieform.Instance.Show();
Movieform.Instance.Play();

---

您想在其他窗体中显示相同的

axshockwavelash1

，还是想在其他窗体中显示与当前的

axshockwavelash1

类似的新实例？我想拥有以前打开的窗体的属性。看起来您需要创建用户控件，可以在许多窗体上重复使用。这就是你想要的吗？只是属性

电影

？甚至方法

flashForm.Controls[“axshockwavelash1”].Show（）

？MOVIE是一个变量，我这样定义它来设置axShocwavflash1:public string MOVIE的值{get{return this.axshockwavelash1.MOVIE；}set{this.axshockwavelash1.MOVIE=value；}
