the error i have on my xaml is " The file 'Images\logo.png' is not part of the project or its 'Build Action' property is not set to 'Resource'. Can anyone help me explain, thanks

推荐答案

在生成操作，你可以标记的图像文件的内容或资源。使用图像中的ImageBrush的语法取决于你选择哪一个是不同的。

In the build action, you can mark the image file as content or as resource. The syntax to use the image in an ImageBrush is different depending on which one you choose.

下面是标记为一个图像文件的内容

Here is a image file marked as content.

要设置按钮的背景到该图像使用下面的code。

To set the button background to this image use the following code.

 var brush = new ImageBrush();
 brush.ImageSource = new BitmapImage(new Uri("Images/ContentImage.png",UriKind.Relative));
 button1.Background = brush;

下面是标记为一个图像文件的资源

Here is an image file marked as resource.

要按钮背景设置为资源图片请使用以下code。

To set the button background to the resource image use the following code.

  Uri resourceUri = new Uri("Images/ResourceImage.png", UriKind.Relative);
  StreamResourceInfo streamInfo = Application.GetResourceStream(resourceUri);

  BitmapFrame temp = BitmapFrame.Create(streamInfo.Stream);
  var brush = new ImageBrush();
  brush.ImageSource = temp;

  button1.Background = brush;
