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 using Insert instead of Add.
ArrayList myAL = new ArrayList();
myAL.Insert( 0, "The" );
myAL.Insert( 1, "fox" );
myAL.Insert( 2, "jumps" );
myAL.Insert( 3, "over" );
myAL.Insert( 4, "the" );
myAL.Insert( 5, "dog" );
// Creates and initializes a new Queue.
Queue myQueue = new Queue();
myQueue.Enqueue( "quick" );
myQueue.Enqueue( "brown" );
// Displays the ArrayList and the Queue.
Console.WriteLine( "The ArrayList initially contains the following:" );
PrintValues( myAL );
Console.WriteLine( "The Queue initially contains the following:" );
PrintValues( myQueue );
// Copies the Queue elements to the ArrayList at index 1.
myAL.InsertRange( 1, myQueue );
// Displays the ArrayList.
Console.WriteLine( "After adding the Queue, the ArrayList now contains:" );
PrintValues( myAL );
// Search for "dog" and add "lazy" before it.
myAL.Insert( myAL.IndexOf( "dog" ), "lazy" );
// Displays the ArrayList.
Console.WriteLine( "After adding \"lazy\", the ArrayList now contains:" );
PrintValues( myAL );
// Add "!!!" at the end.
myAL.Insert( myAL.Count, "!!!" );
// Displays the ArrayList.
Console.WriteLine( "After adding \"!!!\", the ArrayList now contains:" );
PrintValues( myAL );
// Inserting an element beyond Count throws an exception.
try {
myAL.Insert( myAL.Count+1, "anystring" );
} catch ( Exception myException ) {
Console.WriteLine("Exception: " + myException.ToString());
}
}
public static void PrintValues( IEnumerable myList ) {
foreach ( Object obj in myList )
Console.Write( " {0}", obj );
Console.WriteLine();
}
}输出：
The ArrayList initially contains the following: The fox jumps over the dog The Queue initially contains the following: quick brown After adding the Queue, the ArrayList now contains: The quick brown fox jumps over the dog After adding "lazy", the ArrayList now contains: The quick brown fox jumps over the lazy dog After adding "!!!", the ArrayList now contains: The quick brown fox jumps over the lazy dog !!! Exception: System.ArgumentOutOfRangeException: Insertion index was out of range. Must be non-negative and less than or equal to size. Parameter name: index at System.Collections.ArrayList.Insert(Int32 index, Object value) at SamplesArrayList.Main()
