You should not use ShareLinkTask for sharing photos. You should use ShareMediaTask. You can more information and how to implement ShareMediaTask by clicking link I provided herewith.
Here's the code:
CameraCaptureTask cameraCaptureTask = new CameraCaptureTask();
//declare it globally
cameraCaptureTask.Completed += cameraCaptureTask_Completed;
//declare it in Constructor
cameraCaptureTask.Show();
//declare it in any method.
For example, button click event. By using this method, you can capture the list box.
//declare this method anywhere in the cs page
void cameraCaptureTask_Completed(object sender, PhotoResult e)
{
if(e.TaskResult == TaskResult.OK)
{
ShowShareMediaTask(e.OriginalFileName);
}
}
void ShowShareMediaTask(string path)
{
ShareMediaTask shareMediaTask = new ShareMediaTask();
shareMediaTask.FilePath = path;
shareMediaTask.Show();
}
Now, You can easily take screenshot of app's listbox and share it with any of the social networks where user installed on their phone. Cheers.!
