我正在尝试通过后台工作程序在与调度程序不同的类中运行一个函数,并让它更新每次迭代的进度。我没有收到任何错误,后台工作人员运行正常,但我的文本框永远不会更新......
public partial class MainWindow : Window
{
public BackgroundWorker worker = new BackgroundWorker();
public MainWindow()
{
InitializeComponent();
worker.WorkerReportsProgress = true;
worker.DoWork += new DoWorkEventHandler(workerDoWork);
worker.ProgressChanged += new ProgressChangedEventHandler(workerProgressChanged);
}
private void myButtonClick(object sender, RoutedEventArgs e)
{
worker.RunWorkerAsync();
}
void workerDoWork(object sender, DoWorkEventArgs e)
{
yv_usfm.convert(worker);
}
void workerProgressChanged(object sender, ProgressChangedEventArgs e)
{
myTextBox.Text = "some text";
}
}
public class yv_usfm
{
public static void convert(BackgroundWorker worker)
{
int i = 1;
while (i < 100)
{
worker.ReportProgress(i);
i++;
}
}
}
