如何在代码中设置背景图片? [英] how can I set a background image in code?

问题描述

如果要将图像设置为文本框的背景，则可以在axml中使用以下代码:

If I want to set a image as background on a textBox I can use this code in the axml:

<Grid>
 <Grid.Background>
    <ImageBrush ImageSource="MyImage.jpg" />
 </Grid.Background>
 <TextBlock Text="Some Text" />
</Grid>

但是，我正在尝试用代码创建一个TextBlock:

However, I am creating a TextBlock in code, I amtrying this:

TextBox myTextBox = new TextBox();

但是以这种方式，我不知道如何访问ImageBrush属性.

But in this way I don't know how to access to the ImageBrush property.

哪种方法可以在代码中添加背景?

Which is the way to add a background in code?

非常感谢.

推荐答案

提供了MyImage.jpg是应用程序当前文件夹中的文件，您可以编写

Provided that MyImage.jpg is a file in the application's current folder, you could write

myTextBox.Background = new ImageBrush(new BitmapImage(new Uri("MyImage.jpg")));

如果它是资源文件，则必须使用资源文件包URI :

If it's a Resource File, you would have to use a Resource File Pack URI:

myTextBox.Background =
    new ImageBrush(new BitmapImage(new Uri("pack://application:,,,/MyImage.jpg")));
