示例1: Main
//引入命名空间
using System;
using System.Collections;
public class SamplesArrayList {
public static void Main() {
// Creates and initializes a new ArrayList.
ArrayList myAL = new ArrayList();
myAL.Add( "The" );
myAL.Add( "quick" );
myAL.Add( "brown" );
myAL.Add( "fox" );
myAL.Add( "jumps" );
// Displays the count, capacity and values of the ArrayList.
Console.WriteLine( "Initially," );
Console.WriteLine( " Count : {0}", myAL.Count );
Console.WriteLine( " Capacity : {0}", myAL.Capacity );
Console.Write( " Values:" );
PrintValues( myAL );
// Trim the ArrayList.
myAL.TrimToSize();
// Displays the count, capacity and values of the ArrayList.
Console.WriteLine( "After TrimToSize," );
Console.WriteLine( " Count : {0}", myAL.Count );
Console.WriteLine( " Capacity : {0}", myAL.Capacity );
Console.Write( " Values:" );
PrintValues( myAL );
// Clear the ArrayList.
myAL.Clear();
// Displays the count, capacity and values of the ArrayList.
Console.WriteLine( "After Clear," );
Console.WriteLine( " Count : {0}", myAL.Count );
Console.WriteLine( " Capacity : {0}", myAL.Capacity );
Console.Write( " Values:" );
PrintValues( myAL );
// Trim the ArrayList again.
myAL.TrimToSize();
// Displays the count, capacity and values of the ArrayList.
Console.WriteLine( "After the second TrimToSize," );
Console.WriteLine( " Count : {0}", myAL.Count );
Console.WriteLine( " Capacity : {0}", myAL.Capacity );
Console.Write( " Values:" );
PrintValues( myAL );
}
public static void PrintValues( IEnumerable myList ) {
foreach ( Object obj in myList )
Console.Write( " {0}", obj );
Console.WriteLine();
}
}输出：
Initially, Count : 5 Capacity : 16 Values: The quick brown fox jumps After TrimToSize, Count : 5 Capacity : 5 Values: The quick brown fox jumps After Clear, Count : 0 Capacity : 5 Values: After the second TrimToSize, Count : 0 Capacity : 16 Values:
示例2: ArrayList.Clear()
//引入命名空间
using System;
using System.Collections;
class MainClass
{
static void Main(string[] args)
{
ArrayList a = new ArrayList(10);
int x = 0;
a.Add( ++x);
a.Add( ++x);
a.Add( ++x);
a.Add( ++x);
a.Remove(x);
a.RemoveAt(0);
a.Clear();
}
