推荐答案
new DownloadProgressChangedEventHandler(ProgressChanged)
to
new DownlaodProgressChangedEventHandler(DownloadProgressChanged)
所以方法名称不会干扰其他 ProgressChanged 方法。
然后实现
so the method name doesn''t interfere with the "other" ProgressChanged method.
Then implement
public void DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
DownloadProgressBar.Value = e.ProgressPercentage;
}
