开始一个线程处理读取的文件并且更新到listbox中：
//处理数据:
private void StartBrowser(string path)
{
UpdateFolderPath invoker = new UpdateFolderPath(DoUpdateFolder);
this.Dispatcher.Invoke(invoker, path); UpdateFolder = new Thread(GetFiles);
if (UpdateFolder.ThreadState == ThreadState.Running)
{
UpdateFolder.Abort();
}
UpdateFolder.Start(); } protected void DoUpdateFolder(string path)
{
this.tbk_ForderPath.Text = path;
this.folderPath = path;
} private void GetFiles()
{
if (this.listItem.Count > )
{
this.listItem.RemoveAll(delegate(object s) { return s == null; });
}
try
{
files = Directory.GetFiles(folderPath, "*.*", SearchOption.AllDirectories);
foreach (string file in files)
{
FileInfo fi = new FileInfo(file); UpdateListUI update = new UpdateListUI(DoAddItem); this.Dispatcher.Invoke(update, fi); }
}
catch
{
System.Windows.MessageBox.Show("Access some files is denied. ");
}
} protected void DoAddItem(object item)
{
try
{
System.Drawing.Icon icon = Win32.GetIcon(item.ToString(), false);
FileInfo fileInfo = item as FileInfo;
DockPanel dp = new DockPanel();
System.Windows.Controls.Image img = new System.Windows.Controls.Image();
img.Height = ;
img.Width = ;
img.Source = icon.ToImageSource();
Run r1 = new Run(fileInfo.Name + "(" + fileInfo.Length + " Byte)");
Run r2 = new Run(fileInfo.FullName);
TextBlock tbk1 = new TextBlock();
tbk1.Inlines.Add(r1);
tbk1.Inlines.Add(new LineBreak());
tbk1.Inlines.Add(r2);
dp.Children.Add(img);
dp.Children.Add(tbk1); this.listbox1.Items.Add(dp);
this.listbox1.ScrollIntoView(this.listbox1.Items[this.listbox1.Items.Count - ]); this.listItem.Add(dp); this.pBar.Maximum = listItem.Count;
}
catch
{
}
finally
{ }
}
开一个一个线程处理读取的数据传到子窗体：
private void DoWork()
{
UpdateListUI update = new UpdateListUI(DoUpdateItem);
foreach (object item in listItem)
{
this.Dispatcher.Invoke(update, item);
}
} protected void StopWork()
{
if (UpdateList != null)
UpdateList.Abort();
if (UpdateFolder != null)
UpdateFolder.Abort();
if (UpdatePBar != null)
UpdatePBar.Abort(); Environment.Exit();
}
更新进度条的值：
protected void DoUpdateItem(object item)
{
var index=listItem.FindIndex(
delegate(object i)
{
return i==item;
});
//this.listbox1.SelectedIndex = index; this.pBar.Visibility = Visibility.Visible;
this.pBar.Value = index+;
if (pBar.Value==pBar.Maximum)
{
this.pBar.Visibility = Visibility.Hidden;
}
}
将Icon转化成ImageSource
这个是Icon的扩展方法：
internal static class IconUtilities
{
[DllImport("gdi32.dll", SetLastError = true)]
private static extern bool DeleteObject(IntPtr hObject); public static ImageSource ToImageSource(this Icon icon)
{
Bitmap bitmap = icon.ToBitmap();
IntPtr hBitmap = bitmap.GetHbitmap(); ImageSource wpfBitmap = Imaging.CreateBitmapSourceFromHBitmap(
hBitmap,
IntPtr.Zero,
Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions()); if (!DeleteObject(hBitmap))
{
throw new Win32Exception();
} return wpfBitmap;
}
}
