线程化，让一个线程知道其他线程的进度 [英] Threading, let one thread know the others progress

问题描述

好吧，好一阵子了，我决定只使用线程.我正在使用语法荧光笔，但通常使用的文件大小却使我的性能一直很差.因此，我做了两种形式，第一种形式以纯文本形式显示文件，并且当您单击以启动这样的新线程时，按钮上显示"openincolor"

Ok, well I have been at it for a while now and I decided to just use threads. I am making a syntax highlighter but I keep getting terrible performance with the file sizes that it will usually be used for. So I made two forms, the first shows the file in plain text and has a button that says "openincolor" when you click that I start a new thread as such

    private void button1_Click(object sender, EventArgs e)
    {
        ColoringThread colorer = new ColoringThread(this.m_bruteView.Text);
        Thread theThread = new Thread(new ThreadStart(colorer.OpenColorWindow));
        theThread.Start();
    }

    public class ColoringThread
    {
        string text;
        public ColoringThread(string initText)
        {
            text = initText;
        }
        public void OpenColorWindow()
        {
            Form2 form2 = new Form2(text);
            form2.ShowDialog();
        }
    };

我希望此表单在每次完成x线填色时都发送回一条消息.然后，我将考虑并确定进度并将其显示给用户.

I want this form to send back a message each time it has complete say x lines of coloring. Then I will take that and figure out the progress and display it to the user.

我该如何发送消息或事件(...?我可以做到这一点)到我的第一个表单，以使其了解其他进程吗?

How might I go about sending a message, or event(...? can I do that) to my first form to let it know of the others progress?

推荐答案

一种简单的方法是使用事件来报告进度.

One very simple way to do this is with BackgroundWorker. It already provides an event to report progress.
