c# linq returns duplicate data

I have a this linq query:

var fling = (from b in flowering.FlowerViews
                     where ((!string.IsNullOrEmpty(flow_name)) && b.FLOWER_NAME == flow_name) || flow_name==""
                     where ((!string.IsNullOrEmpty(color_name)) && b.COLOR_NAME == color_name) || color_name == ""
                     where ((!string.IsNullOrEmpty(size)) && b.FLOWER_SIZE == size) || size==""
                     where ((low_price!=0) && low_price<= b.FLOWER_PRICE) || low_price==0
                     where ((high_price!=0) && high_price >= b.FLOWER_PRICE)  || high_price==0
                     orderby b.COLOR_NAME
                     select new { b.FLOWER_NAME, b.COLOR_NAME, b.FLOWER_SIZE, b.FLOWER_PRICE, b.CHAR_DESC});

my where clauses work for me but when I run a for each loop over the returned values there 开发者_Python百科is duplicate data because b.CHAR_DESC has 3 values to it where all the other return data only have one. I am wondering if there is a way to get the 3 values assigned to b.CHAR_DESC into a structure that does not cause duplicate b.Flower_name's to show up

Based on this post you should be able to call Distinct() for the anonymous type

var list = fling.Distinct().ToList();

And the compiler will take care of GetHashCode() and Equals() for the anonymous type based on attribute values.

Add .Distinct() at the end of your select clause, after the final parenthesis.
