示例1: InitCache
internal static void InitCache()
{
var files = Directory.EnumerateFiles(Path.Combine(Global.CurrentDir, Global.CacheDir));
foreach (string filename in files)
{
FileInfo fileInfo = new FileInfo(filename);
Uri localFileUri = new Uri(filename);
BitmapImage image = new BitmapImage(localFileUri) { CacheOption = BitmapCacheOption.OnLoad};
images.Add(image.GetHashCode(), new CacheNode<Uri>((int)fileInfo.Length, localFileUri));
}
}示例2: LoadBitmapFromIsoAsync
public static void LoadBitmapFromIsoAsync(
string path,
Action<BitmapImage> callback)
{
ThreadUtil.Execute(() =>
{
byte[] raw = StorageIo.ReadBinaryFile(path);
if (null == raw)
{
callback(null);
return;
}
var stm = new MemoryStream();
stm.Write(raw, 0, raw.Length);
stm.Seek(0, SeekOrigin.Begin);
