Copy image to another folder

I am using Xamaring forms and I am trying to copy selected image path to another location on smartphone but is not working. Any ideas why and how to fix it?

  private async Task btn_AddImg_ClickedAsync(object sender, EventArgs e)
        {
            var file = await CrossFilePicker.Current.PickFileAsync();
            if (file != null)
            {
                Error.IsVisible = true;
                Error.Text = file.FilePath;

                var dirToCreate = Path.Combine(Android.App.Application.Context.FilesDir.AbsolutePath, "WightLossPersonal");
                if (!Directory.Exists(dirToCreate))
                {

                    var x= Directory.CreateDirectory(dirToCreate);
                    System.IO.File.Copy(file.FilePath, dirToCreate, true);

                }
                else
                {
                   System.IO.File.Copy(file.FilePath, dirToCreate, true);
                }

            }
        }

In my Manifest I got permissions 

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Error Message :

"/data/user/0/com.companyname.WightLoss/files/WightLossPersonal is a directory"

enter image description here

Well your main issue is you didn't pass the file name in the new dir. So it's like you are trying to copy the dir itself, not the file !

Basically you have to combine the file name with the dir then pass it to Copy() method.

string destFolder = Path.Combine(dirToCreate, file.Name);
System.IO.File.Copy(file.FilePath, destFolder , true);

but let's make the code more clean. And I'll comment the code for better understanding.

private async Task btn_AddImg_ClickedAsync(object sender, EventArgs e)
        {
            var file = await CrossFilePicker.Current.PickFileAsync();
            if (file != null)
            {
                Error.IsVisible = true;
                Error.Text = file.FilePath;

                var dirToCreate = Path.Combine(Android.App.Application.Context.FilesDir.AbsolutePath, "WightLossPersonal");
                if (!Directory.Exists(dirToCreate))
                {
                      Directory.CreateDirectory(dirToCreate);
                   // var x= Directory.CreateDirectory(dirToCreate); // don't need that variable x here since you don't want to use it later
                    //System.IO.File.Copy(file.FilePath, dirToCreate, true); No need here, will copy it in all ways down .

                }
                //else   // you don't need else, copy the file when finishing the check.
                //{

                  // Make a new path to compine the dir and the fileName
                   string destFolder = Path.Combine(dirToCreate, file.Name);
                   System.IO.File.Copy(file.FilePath, destFolder , true);
                //}

            }


  }
