As result I would like to get a list where ALL persons where the age is duplicate to be removed from the list. For this example "Barry" and "Kate" should not be included in the list.If something is not clear please, let me know....
}).ToList(); may not be logically correct, but syntax should be correct. If you want to get distinct values, why not selecting Distinct ItemID and name?? try that and see if it helps Thursday, July 29, 2010 10:44 AM This is in VB (VS10). Let me know if you need this in C#...
Further, what if we want to get a list of distinct values across all of the lists? It’s easy using the Distinct operator in LINQ. csharpcode 複製 static void Main(string[] args) { List<IEnumerable<KeyValuePair>> blueList = FillList(); IEnumerable<KeyValuePair> items = (from green...
operations, you create a custom aggregate method to compute a single value from a sequence of values. You also create a method that works as a custom filter or a specific data transform for a sequence of values and returns a new sequence. Examples of such methods areDistinct,Skip, and...
Other LINQ methods find elements in a collection, compute values from the elements in a collection, or modify the collection or its elements. These examples help you learn about LINQ methods and how you can use them with your collections, or other data sources. How to find the set ...
Distinct is an extension method on the System.Linq.Enumerable class (which implements the standard query operators) that we can call on the string array (which supports IEnumerable) in order to get the distinct set of items from the collection. (For more information on extension methods, see ...
