[英]UWP - Load image in class library
I have a Universal Windows application that hosts a main menu. 我有一个通用Windows应用程序,主机主菜单。 I want a plugin architecture, where the menu items are added from class libraries.
我想要一个插件架构,其中菜单项是从类库中添加的。
But I can't seem to load images correctly. 但我似乎无法正确加载图像。 I can't get the
ms-appx:///
working, and when I try to add the images as an embedded resource, it hangs: 我无法让
ms-appx:///
工作,当我尝试将图像添加为嵌入式资源时,它会挂起:
var assembly = typeof(CookModule).GetTypeInfo().Assembly;
using (var imageStream = assembly.GetManifestResourceStream("My.Namespace.Folder.ImageName-100.png"))
using (var raStream = imageStream.AsRandomAccessStream())
{
var bitmap = new BitmapImage();
bitmap.SetSource(raStream); //<- Hangs here
I get no exceptions, errors in the output or anything. 我没有例外,输出中的错误或任何东西。 It just hangs there, and the app simply doesn't load the page.
它只是挂在那里,应用程序根本不加载页面。
I have also tried: 我也尝试过:
var bitmap = new BitmapImage(new Uri("/Folder/ImageName-100.png"));
I'm missing something similar to the WPF pack uri's where I can state which assembly to load the image from. 我遗漏了类似于WPF包uri的东西,我可以说明从哪个程序集加载图像。
What is the correct (and working) way of adding a image resource to a Page from a class libary? 从类库中向图像添加图像资源的正确(和工作)方式是什么? (Or does anyone have a working example of ms-appx where the image is in a class library)
(或者有没有人有ms-appx的工作示例,其中图像在类库中)
I can reproduce this issue. 我可以重现这个问题。 Current workaround I used is copying the resource stream to .NET memory stream.
我使用的当前解决方法是将资源流复制到.NET内存流。
var assembly = typeof(CookModule).GetTypeInfo().Assembly;
using (var imageStream = assembly.GetManifestResourceStream("UWP.ClassLibrary.210644575939381015.jpg"))
using (var memStream = new MemoryStream())
{
await imageStream.CopyToAsync(memStream);
memStream.Position = 0;
using (var raStream = memStream.AsRandomAccessStream())
{
var bitmap = new BitmapImage();
bitmap.SetSource(raStream);
display.Source = bitmap;
}
}
