C # a method linq interesting ToObservableCollection ()

Hello,

back after a long wait to publish a post in C # ... who has not ever had to write an extension method ... Today I propose an interesting extension method for linq:

   namespace System.Linq {
 
    public static class      ExtensionMethod   
   { 
         public     static     ObservableCollection     ToObservableCollection  (  this     IEnumerable     e) 
       { 
             if   (e !=   null  ) 
           { 
                 return     new     ObservableCollection    (e); 
           } 
             else   
           { 
                 return     null  ; 
           } 
       }         

     } 

    
 } 
  

a beautiful straight to solve different problems ... to the next!
