需要序列化位图图像silverlight 4 [英] Need serialize bitmapImage silverlight 4

问题描述

大家好！我是Silverlight的初学者.我在项目中使用Silverlight4.
我有一个带有BitmapImage属性的自定义类，目前我所有的属性都标记了DataMember和BitmapImage标记了IgnoreDataMember.我必须序列化该类，但是几个小时后我找不到有关序列化BitmapImage的任何信息.
有人可以提供一些使用BitmapImage属性对类进行序列化和反序列化的示例.
我只知道我必须将其转换为字节，但如何转换回去?请注意，我正在使用Silverlight4.谢谢您

Hello everybody!I''m beginner of Silverlight.I use Silverlight 4 for my project.
I have custom class with BitmapImage property.Currently all my properties has tagged DataMember and BitmapImage tagged IgnoreDataMember. I must serialize this class, but after some hours I couldn''t find nothing about serialize BitmapImage.

http://stackoverflow.com/questions/4308777/wpf-bitmapimage-serialization-deserialization [ ^ ]请参阅注释以进行更改.据我所知，此解决方案应该为您做.这很常见，但是我使用类似这样的东西

http://stackoverflow.com/questions/4308777/wpf-bitmapimage-serialization-deserialization[^] see comments for changes, to make. As far as I see, this solution should do for you. This is very common, but I use something like this

public string ImageToBase64(Image image,
  System.Drawing.Imaging.ImageFormat format)
{
  using (MemoryStream ms = new MemoryStream())
  {
    // Convert Image to byte[]
    image.Save(ms, format);
    byte[] imageBytes = ms.ToArray();

    // Convert byte[] to Base64 String
    string base64String = Convert.ToBase64String(imageBytes);
    return base64String;
  }
}

public Image Base64ToImage(string base64String)
{
  // Convert Base64 String to byte[]
  byte[] imageBytes = Convert.FromBase64String(base64String);
  MemoryStream ms = new MemoryStream(imageBytes, 0, 
    imageBytes.Length);

  // Convert byte[] to Image
  ms.Write(imageBytes, 0, imageBytes.Length);
  Image image = Image.FromStream(ms, true);
  return image;
}
