Clear Method

Stack.Clear Method ()

 

Removes all objects from the Stack.

Namespace:   System.Collections
Assembly:  mscorlib (in mscorlib.dll)

public virtual void Clear()

Count is set to zero, and references to other objects from elements of the collection are also released.

This method is an O(n) operation, where n is Count.

The following example shows how to clear the values of the Stack.

using System;
using System.Collections;

public class SamplesStack  {

   public static void Main()  {

      // Creates and initializes a new Stack.
      Stack myStack = new Stack();
      myStack.Push( "The" );
      myStack.Push( "quick" );
      myStack.Push( "brown" );
      myStack.Push( "fox" );
      myStack.Push( "jumped" );

      // Displays the count and values of the Stack.
      Console.WriteLine( "Initially," );
      Console.WriteLine( "   Count    : {0}", myStack.Count );
      Console.Write( "   Values:" );
      PrintValues( myStack );

      // Clears the Stack.
      myStack.Clear();

      // Displays the count and values of the Stack.
      Console.WriteLine( "After Clear," );
      Console.WriteLine( "   Count    : {0}", myStack.Count );
      Console.Write( "   Values:" );
      PrintValues( myStack );

   }

   public static void PrintValues( IEnumerable myCollection )  {
      foreach ( Object obj in myCollection )
         Console.Write( "    {0}", obj );
      Console.WriteLine();
   }

}
