Convert dictionary values to list using linq

Convert dictionary values to list using linq

You can use LINQ to convert the values of a dictionary to a list. Here's an example:

Dictionary<string, int> dict = new Dictionary<string, int> { { "apple", 1 }, { "banana", 2 }, { "orange", 3 } }; List<int> valuesList = dict.Values.ToList();

In this example, we create a Dictionary<string, int> with three key-value pairs. We then use the Values property of the dictionary to get a collection of all the values in the dictionary, and call the ToList() method to convert the collection to a List<int>. The resulting list will contain all the values of the dictionary in the order they appear in the Values collection.
