C# 图像未显示inXamarin表单ImageCircle插件

我正在使用Xamarin表单开发Android应用程序。我在表单上添加了ImageCircle插件来显示配置文件图像。我想用手机摄像头拍摄的照片更新它。所以要做到这一点，我有这些代码

1.XAML 我也尝试了以下方法，但没有成功：

设置Source=file.Path

使用字节数组

在xaml中{Binding ImageSource}并在代码隐藏中设置ImageSource

上面的代码运行得很好，我可以在监视窗口中看到字节数组/流。但仍然没有显示图像

请注意: 我的方法是老式的WinForm方式，而不是MVVM

插件/模块版本

VS 2019社区16.5.5

Xamarin Android SDK-10.2.0.100

Xamarin.表格4.6.0.800

Xamarin.Plugin.Media 5.0.1

Xamarin.Plugins.Forms.ImageCircle 3.0.0.5

提前感谢

我使用您的代码进行测试，可以拍摄照片并以圆形图像显示

 <StackLayout>
    <!--  Place new controls here  -->
    <controls:CircleImage
        x:Name="ImgProfile"
        Aspect="AspectFit"
        BorderColor="DarkSlateGray"
        BorderThickness="5"
        HeightRequest="150"
        Scale="0.6"
        WidthRequest="150" />
    <ImageButton
        BackgroundColor="Transparent"
        Clicked="ImageButton_Clicked"
        Source="plu3.png" />
</StackLayout>

您可以查看github上的示例：

你能在github分享一个简单的示例吗？我将下载你的示例进行测试。如果它是普通的

图像

，它会显示吗？@Morse-是的，会显示硬编码图像。@CherryBu MSFT-抱歉，我不能。它是专有的，因此不能公开共享整个项目/代码。ImageCircle只是将现有图像转换为圆形。它没有那么灵活。尝试改用FFloading Circle-ImageTransformations
