Xamarin Forms Convert from Image to Base64 from Image Control not from file

Question

I am loading an image from the camera into an Image control. That works beautifully as shown below.

var photo = await Plugin.Media.CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions() { });

if (photo != null)
PhotoImageRear.Source = ImageSource.FromStream(() => { return photo.GetStream(); });

I sometime later need to take the images loaded into that PhotoImageRear control and convert it to a base64 string in order to post it to an API.

What would be the most efficient way of achieving that.

Thanks in advance for your help

From shared code ,once you get the photo, you can use the following code to convert to Base64 .

var stream = photo.GetStream();
var bytes = new byte [stream.Length];
await stream.ReadAsync(bytes, 0, (int)stream.Length);
string base64 = System.Convert.ToBase64String(bytes);
