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 with three elements of the same value.
ArrayList myAL = new ArrayList();
myAL.Add( "the" );
myAL.Add( "quick" );
myAL.Add( "brown" );
myAL.Add( "fox" );
myAL.Add( "jumps" );
myAL.Add( "over" );
myAL.Add( "the" );
myAL.Add( "lazy" );
myAL.Add( "dog" );
myAL.Add( "in" );
myAL.Add( "the" );
myAL.Add( "barn" );
// Displays the values of the ArrayList.
Console.WriteLine( "The ArrayList contains the following values:" );
PrintIndexAndValues( myAL );
// Search for the first occurrence of the duplicated value.
String myString = "the";
int myIndex = myAL.IndexOf( myString );
Console.WriteLine( "The first occurrence of \"{0}\" is at index {1}.", myString, myIndex );
// Search for the first occurrence of the duplicated value in the last section of the ArrayList.
myIndex = myAL.IndexOf( myString, 4 );
Console.WriteLine( "The first occurrence of \"{0}\" between index 4 and the end is at index {1}.", myString, myIndex );
// Search for the first occurrence of the duplicated value in a section of the ArrayList.
myIndex = myAL.IndexOf( myString, 6, 6 );
Console.WriteLine( "The first occurrence of \"{0}\" between index 6 and index 11 is at index {1}.", myString, myIndex );
// Search for the first occurrence of the duplicated value in a small section at the end of the ArrayList.
myIndex = myAL.IndexOf( myString, 11 );
Console.WriteLine( "The first occurrence of \"{0}\" between index 11 and the end is at index {1}.", myString, myIndex );
}
public static void PrintIndexAndValues(IEnumerable myList)
{
int i = 0;
foreach (Object obj in myList)
Console.WriteLine(" [{0}]: {1}", i++, obj);
Console.WriteLine();
}
}输出：
The ArrayList contains the following values: [0]: the [1]: quick [2]: brown [3]: fox [4]: jumps [5]: over [6]: the [7]: lazy [8]: dog [9]: in [10]: the [11]: barn The first occurrence of "the" is at index 0. The first occurrence of "the" between index 4 and the end is at index 6. The first occurrence of "the" between index 6 and index 11 is at index 6. The first occurrence of "the" between index 11 and the end is at index -1.
