Question

我在编译项目时收到此错误不知道指的是什么.. 我试图将图像转换为字节数组，以便将其保存到数据库中

i've updated the versions and nothing happens

private async void btnGuardar(object sender, EventArgs e)
        {
            await DisplayAlert("",converterDemo(Vistaprevia).ToString(),"OK");
        }

 public byte[] converterDemo(Xamarin.Forms.Image x)
        {
            ImageConverter _imageConverter = new ImageConverter();
            byte[] xByte = (byte[])_imageConverter.ConvertTo(x, typeof(byte[]));
            
            return xByte;
        }
