序列化包含BitmapImage的对象 [英] Serializing Object containing BitmapImage

问题描述

这是关于此主题的另一个问题:如何使用反序列化的对象? 我的班上有一些变量存在问题，现在我只是将[XmlIgnore]放在无法序列化的变量前面，因此该类的序列化现在可以使用.

This is a further question about this topic: How to use deserialized object? I have a Problem with some variables in my class, right now I just put [XmlIgnore] infront of the variables wich cannot be serialized, so the serialazation of the class works for now.

我的课看起来像这样:

public class Channel : INotifyPropertyChanged
{
    public int Width { get; set; }
    public int Height { get; set; }
    [XmlIgnore]
    public BitmapImage Logo { get; set; }
    public string CurrentCoverURL { get; set; }
    [XmlIgnore]
    public SolidColorBrush Background { get; set; }
    private string name;
    public string Name
    {
        get { return name; }
        set
        {
            name = value;
            NotifyPropertyChanged("Name");
        }
    }
}

现在，我还需要以某种方式对Bitmapimage和SolidColorBrush进行序列化，以便将这些信息传递给下一个视图.

Now I somehow need to serialize the Bitmapimage and the SolidColorBrush too, so I can pass these informations to my next view.

我找到了一种方法(在C#中序列化位图/.NET到XML )，但这不适用于Windows 8 Apps. System.Drawing.Bitmap在Windows 8中不可用.

I found a way to do this(Serialize a Bitmap in C#/.NET to XML), but this doesn't work for Windows 8 Apps. System.Drawing.Bitmap is not available in Windows 8.

有人可以帮助我解决这个问题吗?

Can someone help me with this issue?

谢谢！

推荐答案

这帮助我完成了同样的事情.只需先转换为字节数组即可.

This helped me do the same thing. Just convert to a byte array first.

您可以像这样将图像包含在JSON有效负载中:

You can include your image in your JSON payload like this:

public class Person
{
    public Int32 PersonId { get; set; }
    public String FirstName { get; set; }
    public byte[] Image { get; set; }
}

或者您可以将imageUri包含在JSON有效负载中，如下所示:

or you can include the imageUri in your JSON payload like this:

public class Person
{
    public Int32 PersonId { get; set; }
    public String FirstName { get; set; }
    public String ImageUri { get; set; }
}

您可以将位图图像转换为这样的字节数组；

And you can convert your bitmapimage to a byte array like this;

    public static byte[] ConvertToBytes(BitmapImage bitmapImage)
    {
        using (var ms = new MemoryStream())
        {
            var btmMap = new WriteableBitmap
                (bitmapImage.PixelWidth, bitmapImage.PixelHeight);

            // write an image into the stream
            btmMap.SaveJpeg(ms, bitmapImage.PixelWidth, bitmapImage.PixelHeight, 0, 100);

            return ms.ToArray();
        }
    }
