Syntax: public void Clear (); Below are the programs to illustrate the use of the above-discussed method: Example 1: csharp // C# code to remove all pairs // from SortedDictionary using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Create a new dictionary of // strings, with string keys. SortedDictionary<string, string> myDict = new SortedDictionary<string, string>(); // Adding key/value pairs in myDict myDict.Add("Australia", "Canberra"); myDict.Add("Belgium", "Brussels"); myDict.Add("Netherlands", "Amsterdam"); myDict.Add("China", "Beijing"); myDict.Add("Russia", "Moscow"); myDict.Add("India", "New Delhi"); // To get count of key/value pairs in myDict Console.WriteLine("Total key/value pairs " + "in myDict are : " + myDict.Count); // Remove all pairs from the Dictionary myDict.Clear(); Console.WriteLine("After clear operation"); // To get count of key/value pairs in myDict Console.WriteLine("Total key/value pairs in" + " myDict are : " + myDict.Count); } } Output: Total key/value pairs in myDict are : 6 After clear operation Total key/value pairs in myDict are : 0 Example 2: csharp // C# code to remove all pairs // from SortedDictionary using System; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Create a new SortedDictionary of // int, with int keys. SortedDictionary<int, int> myDict = new SortedDictionary<int, int>(); // Adding key/value pairs in myDict myDict.Add(9, 8); myDict.Add(3, 4); myDict.Add(4, 7); myDict.Add(1, 7); // To get count of key/value pairs in myDict Console.WriteLine("Total key/value pairs " + "in myDict are : " + myDict.Count); // Remove all pairs from the Dictionary myDict.Clear(); Console.WriteLine("After clear operation"); // To get count of key/value pairs in myDict Console.WriteLine("Total key/value pairs" + " in myDict are : " + myDict.Count); } } Output: Total key/value pairs in myDict are : 4 After clear operation Total key/value pairs in myDict are : 0 Reference: https://docs.microsoft.com/en-us/dotnet/api/system.collections.generic.sorteddictionary-2.clear?view=netframework-4.7.2 Comment More infoAdvertise with us Next Article C# | SortedDictionary.Clear() Method rupesh_rao Follow Improve Article Tags : C# CSharp-method CSharp-Generic-Namespace CSharp SortedDictionary Class Similar Reads C# | SortedDictionary.Add() Method This is used to add a specified key and value to the sorted dictionary.
