转换Base64字符串到BitmapImage c# Windows Phone

本文关键字：Windows Phone BitmapImage Base64 字符串转换 | 更新日期: 2023-09-27 18:02:57

我从服务器收到一个image/jpeg;base64字符串。我如何将这个字符串转换为BitmapImage并设置为Image。源?

string imgStr = "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAAQABAAD .... ";
BitmapImage bmp = Base64StringToBitmap(imgStr);
myImage.Source = bmp;

提前感谢!

我找到了我的问题的解决方案:

public static BitmapImage Base64StringToBitmap(string  base64String)
{
    byte[] byteBuffer = Convert.FromBase64String(base64String);
    MemoryStream memoryStream = new MemoryStream(byteBuffer);
    memoryStream.Position = 0;
    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.SetSource(memoryStream);
    memoryStream.Close();
    memoryStream = null;
    byteBuffer = null;
    return bitmapImage;
}
