ArrayList [ ^ ]

使用ArrayList [ ^ ]

以下代码示例演示如何创建和初始化 ArrayList [ ^ ]以及如何打印出它的值

 使用系统; 
 我们ing  System.Collections; 
  public   class  SamplesArrayList {
 
  public   static   void  Main（）{
 
  //  创建并初始化一个新的ArrayList。 
 ArrayList myAL =  new  ArrayList（）; 
 myAL.Add（  Hello）; 
 myAL.Add（  World）; 
 myAL.Add（ ！）; 
 
  //  显示ArrayList的属性和值。 
 Console.WriteLine（  myAL）; 
 Console.WriteLine（  Count：{0}，myAL.Count）; 
 Console.WriteLine（ 容量：{0}，myAL.Capacity）; 
 Console.Write（ 值：）; 
 PrintValues（myAL）; 
} 
 
  public   static   void  PrintValues（IEnumerable myList）{
  foreach （ Object  obj  in  myList）
 Console.Write（  {0}，obj）; 
 Console.WriteLine（）; 
} 
 
} 
 
 
  / *   
此代码生成类似于以下内容的输出：
 
 myAL 
计数：3 
容量：4 
值：Hello World！ 
 
 * /

如何使用C＃ArrayList类 [ ^ ]

你可以试试像

 ArrayList arr =  new  ArrayList（）; 
 
  for （ int  iIndex =  0 ; iIndex <  arr.Count; iIndex ++）
 {
  object  o = arr [iIndex]; 
} 

但我宁愿一起去



列表类 [ ^ ]和 List.Count Property [ ^ ]

ArrayList[^]
Use ArrayList[^]

The following code example shows how to create and initialize an ArrayList [^]and how to print out its values"

using System;
using System.Collections;
public class SamplesArrayList  {

   public static void Main()  {

      // Creates and initializes a new ArrayList.
      ArrayList myAL = new ArrayList();
      myAL.Add("Hello");
      myAL.Add("World");
      myAL.Add("!");

      // Displays the properties and values of the ArrayList.
      Console.WriteLine( "myAL" );
      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();
   }

}


/* 
This code produces output similar to the following:

myAL
    Count:    3
    Capacity: 4
    Values:   Hello   World   !

*/

How to use C# ArrayList Class[^]

You can try something like

ArrayList arr = new ArrayList();

for (int iIndex = 0; iIndex < arr.Count; iIndex++)
{
    object o = arr[iIndex];
}

But I would rather go with

List Class[^] and List.Count Property[^]
