C# | SortedDictionary.Clear() Method
This method is used to remove all key/value pairs from the SortedDictionary<TKey, TValue>.
Syntax:
public void Clear ();
Below are the programs to illustrate the use of the above-discussed method:
Example 1:
// 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:
// 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
