Question

c# 给ArrayList添加元素 用AddRange（）方法 ，怎么添加呢？给个添加语句代码就好。

Answer 1

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" );

// Creates and initializes a new Queue.
Queue myQueue = new Queue();
myQueue.Enqueue( "jumped" );
myQueue.Enqueue( "over" );
myQueue.Enqueue( "the" );
myQueue.Enqueue( "lazy" );
myQueue.Enqueue( "dog" );

// Displays the ArrayList and the Queue.
Console.WriteLine( "The ArrayList initially contains the following:" );
PrintValues( myAL, '\t' );
Console.WriteLine( "The Queue initially contains the following:" );
PrintValues( myQueue, '\t' );

// Copies the Queue elements to the end of the ArrayList.
myAL.AddRange( myQueue );

// Displays the ArrayList.
Console.WriteLine( "The ArrayList now contains the following:" );
PrintValues( myAL, '\t' );
}

public static void PrintValues( IEnumerable myList, char mySeparator ) {
foreach ( Object obj in myList )
Console.Write( "{0}{1}", mySeparator, obj );
Console.WriteLine();
}

}

/*
This code produces the following output.

The ArrayList initially contains the following:
The quick brown fox
The Queue initially contains the following:
jumped over the lazy dog
The ArrayList now contains the following:
The quick brown fox jumped over the lazy dog

方法很多，下面是一种：
List<String> strlist = new List<string> { "test1", "test5", "test9", "test13", "test18", "test24" };
ArrayList myAL = new ArrayList();
myAL.AddRange(strlist.ToArray());
