更改NotifyIcon的在不同形式

问题描述

我有一个窗体（Form1）在其上有一个NotifyIcon的。我还有一个窗体（Form），我想从改变的NotifyIcon的图标。每当我使用此代码，我得到一个额外的图标在系统托盘中显示出来，而不是改变目前的图标：

Form1中（ICO是NotifyIcon的名称）：

 公共字符串DisplayIcon 
 {
集合{ico.Icon =新图标（的System.Reflection .Assembly.GetExecutingAssembly（）GetManifestResourceStream（Alerts.Icons+值））; } 
} 
  

窗体2：

  Form1中Form1中=新Form1的（）; 
 form1.DisplayIcon =on.ico; 
  

我怀疑是有事情做与创建的Form2 Form1的一个新实例，但我不知道如何访问DisplayIcon没有这样做。谢谢

UDPATE：我在表格上写2自定义属性有点困惑，这将是这样的：

$ b

 公共窗体Form1 
 {} 
 
集合{值} p $ p> 
 
解决方案
 
我假设Form1中在一个点上创建窗体2。在这一点上，你可以通过Form1的到窗体2的引用，以便窗口2可以访问Form1的DisplayIcon财产。 
 
 
 
所以，你最终会与像
  //某处在Form1 
公共无效btnShowFormTwoClick的代码（对象发件人，EventArgs五）
 {
 Form2的窗体2 =新Form2的（）; 
 form2.Form1 =这一点; //如果不Form1的代码中完成的，你不会用这个，但Form1的实例变量
 form2.Show（）; 
} 
 
 //某处窗口2 
公共Form1的Form1的{获取的代码;集;} //要创造一个在Form1参考storred财产。 
 this.Form1.DisplayIcon =on.ico; 
  
 
I have a form (Form1) that has a NotifyIcon on it.  I have another form (Form2) that I would like to change the NotifyIcon's icon from.  Whenever I use this code, I get an extra icon that shows up in the system tray, instead of changing the current icon:
Form1 (ico is the name of the NotifyIcon):
public string DisplayIcon
{
    set { ico.Icon = new Icon(System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("Alerts.Icons." + value)); }
}
Form2:
Form1 form1 = new Form1();
form1.DisplayIcon = "on.ico";
I suspect is has something to do with creating a new instance of Form1 on Form2, but I'm not sure how to access "DisplayIcon" without doing this.  Thanks.
UDPATE: I'm a little confused on writing the custom property on Form 2, would it be something like:
public Form Form1
{
    set {value;}
}
 解决方案 
I assume form1 at one point creates form2. At that point you can pass a reference of form1 to form2 so form2 can access the DisplayIcon property of form1. 
So you would end up with something like
//Somewhere in the code of form1
public void btnShowFormTwoClick(object sender, EventArgs e) 
{
    Form2 form2 = new Form2();
    form2.Form1 = this; //if this isn't done within form1 code you wouldn't use this but the form1 instance variable
    form2.Show();
}

//somewhere in the code of form2
public Form1 Form1 { get;set;} //To create the property where the form1 reference is storred.
this.Form1.DisplayIcon = "on.ico";
