我有背景工人的read,有一.。 对于每一种变迁,我要更新一个文本箱,显示用户对正在做的事情的标识。 例如,如果用户正在拆除200个头条线站点,就会说:

Scraped site1.net Scraped site2.net Scraped site3.net

我所能看到的唯一事情是报告进展,只是只是一劳永逸。 我没有用报告这一百分比。 我希望每次火烧。

这是可能的吗?

问题回答

而是使用第二个超负荷。 将百分率提高到0,并将用户国置于为这些站点铺设或铺设的位置。

myBackgroundWorker.ReportProgress(int percentProgress, object userState);

例:

    private void myBackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
    {
        // Set your sites dynamically here.

        string[] sites = new string[]
        {
            "Test.com",
            "Example.net",
            "Google.com"
        };

        myBackgroundWorker.ReportProgress(0, sites);
    }

    private void myBackgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        string[] sites = (string[])e.UserState;

        // Enjoy your string array.
    }

DoWork 活动组拥有“物品”类型的财产“抵押”,可以用来将你想要的东西传递给背景工人。

您可以确定一种看管模型或其他具有约束力的来源的可怕财产,然后将其作为论据通过;然后,背景工作者可以更新这一财产,如果你正在使用WPF或银灯,可以通过约束性或通过WPF发送器更新你。
