Este método se usa para eliminar todos los pares clave/valor del Diccionario<TKey,TValue>.
Sintaxis:
public void Clear ();
A continuación se muestran los programas para ilustrar el uso del método mencionado anteriormente:
Ejemplo 1:
// C# code to remove all pairs
// from Dictionary
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Create a new dictionary of
// strings, with string keys.
Dictionary<string, string> myDict =
new Dictionary<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);
}
}
Producción:
Total key/value pairs in myDict are : 6 After clear operation Total key/value pairs in myDict are : 0
Ejemplo 2:
// C# code to remove all pairs
// from Dictionary
using System;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Create a new dictionary of
// strings, with string keys.
Dictionary<int, int> myDict =
new Dictionary<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);
}
}
Producción:
Total key/value pairs in myDict are : 4 After clear operation Total key/value pairs in myDict are : 0
