C# sort dictionary with linq

You can do that using:

List<Product> productList = dictionary.OrderByDescending(kp => kp.Value)
                                      .Select(kp => kp.Key)
                                      .ToList();

MyDict.OrderByDescending(x => x.Value).Select(p => p.Key).ToList();

Try this

List<Product> productList = dictionary.OrderByDescending(x => x.Value).Select(x => x.Key).ToList();
