Select distinct record

Question

Hello,

 

My code is:

 

var ListofRoute = _DatabaseContext.RouteMaster.ToList();

return ListofRoute.ToArray();

 

I need to select distinct record only. I tries :

 

var ListofRoute = _DatabaseContext.RouteMaster.Distinct().ToList();

return ListofRoute.ToArray();

 

But its not working. Please help.

Thanks in advance
