How Can I Efficiently Sort a Dictionary by Its Values Using LINQ in C#?

C# linq dictionary value sorting

Dictionary is a common key value in the program. Dictionary sorting is a common problem. This article will introduce how to use the C#linq (Language Integration inquiry) framework to sort according to the dictionary value.

linq method

Traditional methods usually need to create a custom class to achieve the sorting logic of dictionary values. And LinQ provides a more concise and efficient solution:

This code creates a

collection called

Dictionary<string, int> myDict = new Dictionary<string, int>();
myDict.Add("one", 1);
myDict.Add("four", 4);
myDict.Add("two", 2);
myDict.Add("three", 3);

var sortedDict = from entry in myDict orderby entry.Value ascending select entry;

, which contains the original dictionary entry arranged by the litter. You can iterate to access the key value pair after sorting.

sortedDict Flexibility and other options IEnumerable sortedDict

LINQ not only provides a function of sorting, but also allows selected specific data according to conditions. For example, you can use the operator to easily select the top 10 or 20 entries, or use the

operator to screen the entry according to other conditions. In addition, you can combine multiple sorting conditions by linking and operations.

Summary Take Where OrderBy Sorting the dictionary by linq by value is an efficient and flexible method. It does not need to create a custom class, and provides multiple data operations and sorting options. ThenBy
