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?

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。
