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
