形式之间的沟通 [英] Communicating between forms
问题描述
我想知道如何使用C＃形式之间的沟通？
I would like to know how to communicate between forms using C#?
在Visual Basic中这是比较容易，因为每个形式有它自己的实例，用C＃这是不同的。
In Visual Basic it was easier since each form had it's own instance, with C# it's different.
在程序 I级设置的握住我的形式公开和静态变量：
In the Program Class I setup a public and static variable that hold my form:
public static FormProcess2 frmProcess2 = null;
然后在主方法创建表格，显示它：
Then in the Main method I create the form and show it up:
frmProcess2 = new FormProcess2();
frmProcess2.ShowDialog();
现在，当这种形式加载时，它加载了处理XML文件的后台进程。
并且处理所有文件的方法，在另一个类的名称 XMLParser的。
所以在的BackgroundWorker 的doWork 我通过加载方法：
Now when that form loads, it load a background process that process XML files.
And the method that process all the files are in another class name XMLParser.
So in the BackgroundWorker doWork I load that method by:
XMLParser.Start();
现在的问题是，我怎么能修改 XMLParser的类的<code> frmProcess2 控件？
我想它来显示什么正在改变标签文本以及放一些漂亮的进度条有更新。
Now the question is, how I can modify the frmProcess2 controls in the XMLParser class?
I wanted it to show what's being updated by changing the label text as well as put some nice progress bar there.
但我不能访问 Program.frmProcess2 控制，我只能访问是它的默认值只有...
But I can't access the Program.frmProcess2 controls, all I can access is it's defaults only...
