Check if some items are same in a c# list

Question

I want to check if some items are same in a list based on a item present in the list.

List<ProductDetailDTO> productDTOs;

The ProductDetailDTO is -

public class ProductDetailDTO
{
    public int ProductId { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public byte[] Image { get; set; }
    public string Description { get; set; }
    public string Brand { get; set; }
    public string GUID { get; set; }
    public string VariantName { get; set; }
    public string VariantValue { get; set; }
    public decimal Price { get; set; }
}

Now, I want to display all VariantName and VariantValue with the same GUIDs together.

How can I achieve this?

try with this

productDTOs.GroupBy(x => x.GUID,(key,item) => new
            {
                VariantName= item.Select(y=>y.VariantName),
                VariantValue = item.Select(y => y.VariantValue),

            }).ToList()

Minor recommendation to parse the guids. Note they're stored in the DTO as a string right now. Could be dupes uncaught. – clarkitect Sep 09 '18 at 17:32

How can I display all my variants with the same GUIDs together? – Suyash Gupta Sep 10 '18 at 06:29
@mukeshkudi No it didn't. What I exactly want is to display the variants with the same GUIDs together. – Suyash Gupta Sep 10 '18 at 07:09
