Problem with DateTime when the value is null

FabienNAPPA

Hi,

When the date value is null I get an error. How to solve this problem?

Thanks

private void QueryTask_ExecuteCompleted(object sender, QueryEventArgs args) //OK cleopatre         {   var featureSet = args.FeatureSet;   foreach (Graphic feature in featureSet.Features)               {   var Query_DateClosed = (DateTime)feature.Attributes["DateClosed"];   if (Query_DateClosed == null){    MessageBox.Show("is null");   }  }          }
