C#程序启动项的设置方法

本文为大家分享了c#程序启动项的设置方法，供大家参考，具体内容如下

托盘图标设置

新建一个notifyicon，会在托盘处显示一个图标。

notifyicon.icon可以直接设置一个ico图片，也可以延用原有程序的图标。

notifyicon.icon = system.drawing.icon.extractassociatedicon(application.executablepath);

public partial class mainwindow : window
 {
  private notifyicon notifyicon;

  public mainwindow()
  {
   initializecomponent();
   setnotifyicon();
   this.hide();
  }

  #region notifyicon

  private void setnotifyicon()
  {
   this.notifyicon = new notifyicon();
   this.notifyicon.balloontiptext = "磁盘清理工具";
   this.notifyicon.showballoontip(2000);
   this.notifyicon.text = "磁盘清理工具:每20天清理一次";
   this.notifyicon.icon = system.drawing.icon.extractassociatedicon(application.executablepath);
   this.notifyicon.visible = true;
   //打开菜单项
   menuitem open = new menuitem("打开");
   open.click += new eventhandler(show);
   //退出菜单项
   menuitem exit = new menuitem("退出");
   exit.click += new eventhandler(close);
   //关联托盘控件
   menuitem[] childen = new menuitem[] { open, exit };
   notifyicon.contextmenu = new contextmenu(childen);

   this.notifyicon.mousedoubleclick += new mouseeventhandler((o, e) =>
   {
    if (e.button == mousebuttons.left) this.show(o, e);
   });
  }

  private void show(object sender, eventargs e)
  {
   this.visibility = visibility.visible;
   this.showintaskbar = true;
   this.activate();
  }

  private void hide(object sender, eventargs e)
  {
   this.showintaskbar = false;
   this.visibility = visibility.hidden;
  }

  private void close(object sender, eventargs e)
  {
   system.windows.application.current.shutdown();
  }

  #endregion

  #region 窗口

  private void minimizebutton_onclick(object sender, routedeventargs e)
  {
   windowstate = windowstate.minimized;
  }

  private void closebutton_onclick(object sender, routedeventargs e)
  {
   this.hide();
  }

  private void headergrid_onmouseleftbuttondown(object sender, mousebuttoneventargs e)
  {
   if (e.buttonstate == mousebuttonstate.pressed)
   {
    this.dragmove();
   }
  }

  #endregion
 }

禁用多进程启动

//禁止双进程
 bool cancreatenew;
 using (system.threading.mutex m = new system.threading.mutex(true, system.windows.forms.application.productname, out cancreatenew))
 {
  if (!cancreatenew)
  {
   this.shutdown();
  }
 }

删除原有进程

/// <summary>
 /// 删除原有进程
 /// </summary>
 /// <param name="processname"></param>
 private void killprocess(string processname)
 {
  //得到所有打开的进程 
  try
  {
   process currentprocess = process.getcurrentprocess();
   var processes = process.getprocessesbyname(processname).where(process=> process.id!=currentprocess.id);
   foreach (process thisproc in processes)
   {
    //找到程序进程,kill之。
    if (!thisproc.closemainwindow())
    {
     thisproc.kill();
    }
   }
  }
  catch (exception ex)
  {
    
  }
 }

设置开机自启动

private void setappautorun(bool autorun)
 {
  if (autorun) //设置开机自启动 
  {
   string path = system.windows.forms.application.executablepath;
   registrykey rk = registry.localmachine;
   registrykey rk2 = rk.createsubkey(@"software\microsoft\windows\currentversion\run");
   rk2.setvalue("jcshutdown", path);
   rk2.close();
   rk.close();
  }
  else //取消开机自启动 
  {
   registrykey rk = registry.localmachine;
   registrykey rk2 = rk.createsubkey(@"software\microsoft\windows\currentversion\run");
   rk2.deletevalue("jcshutdown", false);
   rk2.close();
   rk.close();
  }
 }

app.cs中完整代码：

public partial class app : application
 {
  public app()
  {
   //禁止双进程
   bool cancreatenew;
   using (system.threading.mutex m = new system.threading.mutex(true, system.windows.forms.application.productname, out cancreatenew))
   {
    if (!cancreatenew)
    {
     this.shutdown();
    }
   }

   setappautorun(true);

   startup += app_startup;
  }

  private void setappautorun(bool autorun)
  {
   if (autorun) //设置开机自启动 
   {
    messagebox.show("设置开机自启动，需要修改注册表", "提示"); // hovertree.com
    string path = system.windows.forms.application.executablepath;
    registrykey rk = registry.localmachine;
    registrykey rk2 = rk.createsubkey(@"software\microsoft\windows\currentversion\run");
    rk2.setvalue("jcshutdown", path);
    rk2.close();
    rk.close();
   }
   else //取消开机自启动 
   {
    messagebox.show("取消开机自启动，需要修改注册表", "提示");
    registrykey rk = registry.localmachine;
    registrykey rk2 = rk.createsubkey(@"software\microsoft\windows\currentversion\run");
    rk2.deletevalue("jcshutdown", false);
    rk2.close();
    rk.close();
   }
  }

  private void app_startup(object sender, startupeventargs e)
  {
   new autocleancachehelper(cleancacheveiwmodel.viewmodel).start();
  }
 }
