Get file path from Content-URI in Android (Xamarin)

GetImageFromURI.cs

private string GetImageFromURI(Uri contentURI)
{
    return MediaStore.Images.Media.GetBitmap(ContentResolver, contentURI);
}

GetRealPathFromURI.cs

private string GetRealPathFromURI(Uri contentURI)
{
    ICursor cursor = ContentResolver.Query(contentURI, null, null, null, null);
    cursor.MoveToFirst();
    string documentId = cursor.GetString(0);
    documentId = documentId.Split(':')[1];
    cursor.Close();

    cursor = ContentResolver.Query(
    Android.Provider.MediaStore.Images.Media.ExternalContentUri,
    null, MediaStore.Images.Media.InterfaceConsts.Id + " = ? ", new [] { documentId }, null);
    cursor.MoveToFirst();
    string path = cursor.GetString(cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data));
    cursor.Close();

    return path;
}

Works perfectly!
send {content://com.android.providers.media.documents/document/image%3A45}
get /storage/emulated/0/Download/20170720_105923.jpg

Hi, I wanted to use it, however I get an error : An object reference is required for ContentResolver.Query . Any help would be very much appreciated!
EDIT : My mistake! Since I am using this code inside a fragment, I just needed to use the activity context like this Activity.ContentResolver.Query and it works amazingly!!
