如何以 xamarin 形式从图库中选择图像？

Question

I'm trying to pick an image from gallery and i've done everything that is in this doc, but i'm getting an error with the "image" object in my .cs implementation.

My .cs code:

 public partial class MyProfilePage : ContentPage
{
  
    public MyProfilePage()
    {
        InitializeComponent();
        BindingContext = new MyProfileViewModel();
    }

   
    async void ImageButton_Clicked(object sender, EventArgs e)
    {
        //(sender as Button).IsEnabled = true;

        Stream stream = await DependencyService.Get<IPhotoPickerService>().GetImageStreamAsync();
        if (stream != null)
        {
            
            image = ImageSource.FromStream(() => stream);
        }

        (sender as Button).IsEnabled = true;
    }
}

Welcome to SO!

but i'm getting an error with the "image" object in my .cs implementation.

You can check the Xaml file that whether contain the x:Name="image" .

Such as follows:

<ContentPage Title="Photo Picker"
             Icon="monkeyicon.png">
    <StackLayout Margin="20,35,20,20" >
        <Label Text="Photo Picker"
               FontAttributes="Bold"
               HorizontalOptions="Center" />
        <Button Text="Pick Photo"
                Clicked="OnPickPhotoButtonClicked" />
        <Image x:Name="image" />
    </StackLayout>        
</ContentPage>

If not works , you can refer to following steps:

• First , you need to share the detail error logs here, and explain this occurs in iOS or Android.

• Second , you also can refer to this official sample Xamarin.Forms - Dependency Service to check where problem is.
