I am trying to get a count of items in a Linq query for items with the same description. My query looks kind of like this

C#

var dataSource = (from t in context.Tags
                  select new
                  {
                        Name = t.Description,
                        Count = //I dont know how to do  this :/
                  });

Any help would be great,
Thanks

You can use grouping for that. See: http://msdn.microsoft.com/en-us/library/bb896250.aspx[^]

For example:

C#

var dataSource = (from t in context.Tags
                  group t by t.Description into t_group
                  select new
                  {
                        Name = t_group.Key,
                        Count = t_group.Count()
                  });
