我正在使用库中的函数来处理非常大的单词文件,我无法更改此功能.
在处理时,我想显示一个进度条,因为无论哪种方式,应用程序看起来都冻结了,用户也不知道它实际上正在工作.
现在我正在使用这样的工人：

现在我正在使用这样的工人：
private void btnClick(object sender,RoutedEventArgs e)
{
BackgroundWorker worker = new BackgroundWorker();
worker.RunWorkerCompleted += worker_RunWorkerCompleted;
worker.WorkerReportsProgress = true;
worker.DoWork += worker_DoConvertOne;
worker.ProgressChanged += worker_ProgressChanged;
worker.RunWorkerAsync();
}
private void worker_DoConvertOne(object sender,DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker;
//The progress bar is filled on 20%
worker.ReportProgress(0);
worker.ReportProgress(10);
worker.ReportProgress(20);
//Processing
myLongLastingFunction(bigWordFile);
//The progress bas is full
worker.ReportProgress(100,"Done Processing.");
}
private void worker_RunWorkerCompleted(object sender,RunWorkerCompletedEventArgs e)
{
MessageBox.Show("Converting finished!");
TestProgressBar.Value = 0;
ProgressTextBlock.Text = "";
}
private void worker_ProgressChanged(object sender,ProgressChangedEventArgs e)
{
TestProgressBar.Value = e.ProgressPercentage;
ProgressTextBlock.Text = (string)e.UserState;
}
