我有一个base64字符串,我想将图像转换控制到这个结果的,要一个形象,并设置源。
I have a base64 string and I want convert that to an image and set the Source of an Image control to the result of that.
通常情况下,我会做,使用 Image.FromStream
,与此类似:
Normally I would do that using Image.FromStream
, similar to this:
Image img;
byte[] fileBytes = Convert.FromBase64String(imageString);
using(MemoryStream ms = new MemoryStream())
{
ms.Write(fileBytes, 0, fileBytes.Length);
img = Image.FromStream(ms);
}
不过, Image.FromStream
方法不会在Windows Phone 的存在,以及轻松搜索只变成了依赖于该方法的结果
However, the Image.FromStream
method does not exist on Windows Phone, and a casual search only turns up results that depend on that method.
您可以使用这样的方法:
You can use a method like this:
public static BitmapImage base64image(string base64string)
{
byte[] fileBytes = Convert.FromBase64String(base64string);
using (MemoryStream ms = new MemoryStream(fileBytes, 0, fileBytes.Length))
{
ms.Write(fileBytes, 0, fileBytes.Length);
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(ms);
return bitmapImage;
}
}
添加图片到你的XAML,像这样的:
Add an image to your XAML, such as this:
<Image x:Name="myWonderfulImage" />
您可以再设置源,像这样:
You can then set the source, like this:
myWonderfulImage.Source = base64image(yourBase64string);
