How to remove duplicate records from a List<T> in C# and return the unique records

[kaushik.debnath]

I want to remove the duplicates from the List, for that I am using following code:

public List<ContainerLevelDetailsResponse> ContainerLevelDetails { get; set; }

public class ContainerLevelDetailsResponse
    {  
        public long ContainerId { get; set; }
        public string Container { get; set; }
        public string Pallet { get; set; }
        public string SKU { get; set; }
        public long CaseCount { get; set; }
    }

List<ContainerLevelDetailsResponse> containerLevelDetails =
new List<ContainerLevelDetailsResponse>();

booking.ContainerLevelDetails = containerLevelDetails.Distinct().ToList<ContainerLevelDetailsResponse>();

But its not working and did not giving unique records. Its not able to remove the duplicates.

Please suggest in this.

Your call to Distinct() is not passing in a lambda which will let it discriminate whether two responses are the same or not.

Distinct like that will only compare if object references are equal, see here for custom equality comparisons: Enumerable.Distinct Method (System.Linq)
