How to sort items of a SortedDictionary with C#

We can use the OrderBy method to sort a SortedDictionary items. The OrderBy method takes a key name that items will be sorted based on. The following code snippet sorts a SortedDictionary items based on a Key.

AuthorList.OrderBy(key => key.Key)

The following code snippet sorts a SortedDictionary by keys and by values.

public void SortSortedDictionary()

{

// Create a SortedDictionary with string key and Int16 value pair

SortedDictionary<string, Int16> AuthorList = new SortedDictionary<string, Int16>();

AuthorList.Add("Mahesh Chand", 35);

AuthorList.Add("Mike Gold", 25);

AuthorList.Add("Praveen Kumar", 29);

AuthorList.Add("Raj Beniwal", 21);

AuthorList.Add("Dinesh Beniwal", 84);

// Sorted by Key

Console.WriteLine("Sorted by Key");

Console.WriteLine("=============");

foreach (KeyValuePair<string, Int16> author in AuthorList.OrderBy(key => key.Key))

{

Console.WriteLine("Key: {0}, Value: {1}", author.Key, author.Value);

}

Console.WriteLine("=============");

// Sorted by Value

Console.WriteLine("Sorted by Value");

Console.WriteLine("=============");

foreach (KeyValuePair<string, Int16> author in AuthorList.OrderBy(key => key.Value))

{

Console.WriteLine("Key: {0}, Value: {1}", author.Key, author.Value);

}
