GetCurrentRangeAtTime Method
Example 

ArcGIS.Desktop.Mapping Namespace > ViewAnimation Class : GetCurrentRangeAtTime Method
The time at which to return the map range.
Gets the map range at the specified time in the track. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
public Range GetCurrentRangeAtTime( 
   TimeSpan time
)
Public Function GetCurrentRangeAtTime( _
   ByVal time As TimeSpan _
) As Range

Parameters

time
The time at which to return the map range.
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Example
Get the range at each frame in the Animation.
public Task<List<Range>> GetInterpolatedMapRanges()
{
  //Return the collection representing the map time for each frame in animation.
  return QueuedTask.Run(() =>
  {
    var mapView = MapView.Active;
    if (mapView != null || mapView.Animation == null)
      return null;

    var animation = mapView.Map.Animation;

    var ranges = new List<Range>();
    //We will use ticks here rather than milliseconds to get the highest precision possible.
    var ticksPerFrame = Convert.ToInt64(animation.Duration.Ticks / (animation.NumberOfFrames - 1));
    for (int i = 0; i < animation.NumberOfFrames; i++)
    {
      var time = TimeSpan.FromTicks(i * ticksPerFrame);
      //Because of rounding for ticks the last calculated time may be greating than the duration.
      if (time > animation.Duration)
        time = animation.Duration;
      ranges.Add(mapView.Animation.GetCurrentRangeAtTime(time));
    }
    return ranges;
  });
}
