如何将独立存储中的图像加载到 Windows 手机上的图像控件中? [英] How to load an image from isolated storage into image control on windows phone?

问题描述

我正在使用此代码在相机动作完成时将图像存储到隔离存储中.

I am using this code for storing the image into isolate storage at the time of camera action completed.

void camera_Completed(object sender, PhotoResult e)
{
    BitmapImage objImage = new BitmapImage();
    //objImage.SetSource(e.ChosenPhoto);
    //Own_Image.Source = objImage;
    using (var isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
    {
        fnam = e.OriginalFileName.Substring(93);
        MessageBox.Show(fnam);
        if (isolatedStorage.FileExists(fnam))
            isolatedStorage.DeleteFile(fnam);

        IsolatedStorageFileStream fileStream = isolatedStorage.CreateFile(fnam);
        BitmapImage bitmap = new BitmapImage();
        bitmap.SetSource(e.ChosenPhoto);

        WriteableBitmap wb = new WriteableBitmap(bitmap);
        wb.SaveJpeg(fileStream, wb.PixelWidth, wb.PixelHeight, 100, 100);
        MessageBox.Show("File Created");
        fileStream.Close();
    }
}

现在我想从独立存储中获取图像并将其显示在我的图像控件中.

Now I want to take the image from isolated storage and display it in my image control.

有可能吗?

推荐答案

是的.您可以使用此函数从隔离存储加载图像:

Yes it is. You can use this function to load image from IsolatedStorage:

private static BitmapImage GetImageFromIsolatedStorage(string imageName)
{
    var bimg = new BitmapImage();
    using (var iso = IsolatedStorageFile.GetUserStoreForApplication())
    {
        using (var stream = iso.OpenFile(imageName, FileMode.Open, FileAccess.Read))
        {
            bimg.SetSource(stream);
        }
    }
    return bimg;
}

用法:

ImageControl.Source = GetImageFromIsolatedStorage(fnam);
