如何以编程方式更改边框背景图像 [英] How to change Border Background image programmatically

问题描述

我正在WPF c#中创建一个媒体播放器应用程序. 我正在使用Media Element来做到这一点.

I am creating a media player app in WPF c#. I am using Media Element to do this.

无论如何，我已经使用<Border> </Border>在某些地方添加边框.

Anyways, I have used <Border> </Border> to add border some places.

    <Border Name="hej1">
                <Border.Background>
                    <ImageBrush ImageSource="Images\music.png"  Stretch="None"/>
                </Border.Background>

                <MediaElement ..../> 
    </Border>

我想以编程方式将ImageSource更改为其他图片，该怎么做?

I want to change the ImageSource to some other picture programmatically, how to do that?

我尝试过但没有成功.

所以对于每首歌曲，<ImageBrush ImageSource="Images\music.png"中的图像都会改变.

So for every song the image in <ImageBrush ImageSource="Images\music.png" is changed.

预先感谢

推荐答案

为ImageBrush分配名称:

Assign a Name to the ImageBrush:

<ImageBrush x:Name="imageBrush" ImageSource="Images\music.png" Stretch="None"/>

然后在代码中使用命名成员:

Then use the named member in code:

var filename = @"Images\title.png";
imageBrush.ImageSource = new BitmapImage(new Uri(filename, UriKind.Relative));

---

或者只需将Border的Background属性的值强制转换为ImageBrush类型:

---

Or simply cast the value of the Border's Background property to type ImageBrush:

var imageBrush = (ImageBrush)hej1.Background;
var filename = @"Images\title.png";
imageBrush.ImageSource = new BitmapImage(new Uri(filename, UriKind.Relative));
