从C#中的ArrayList中删除一系列元素
要从ArrayList中删除一系列元素，代码如下-
示例
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args){
ArrayList list1 = new ArrayList();
list1.Add("A");
list1.Add("B");
list1.Add("C");
list1.Add("D");
list1.Add("E");
list1.Add("F");
list1.Add("G");
list1.Add("H");
list1.Add("I");
Console.WriteLine("Elements in ArrayList1...");
foreach (string res in list1){
Console.WriteLine(res);
}
ArrayList list2 = new ArrayList();
list2.Add("A");
list2.Add("B");
list2.Add("C");
list2.Add("D");
list2.Add("E");
list2.Add("F");
list2.Add("G");
list2.Add("H");
list2.Add("I");
Console.WriteLine("Elements in ArrayList2...");
foreach (string res in list2){
Console.WriteLine(res);
}
Console.WriteLine("Is ArrayList1 equal to ArrayList2? = "+list1.Equals(list2));
list2.RemoveRange(3, 2);
Console.WriteLine("Elements in ArrayList2 after removing elements in a range...");
foreach (string res in list2){
Console.WriteLine(res);
}
}
}输出结果
这将产生以下输出-
Elements in ArrayList1... A B C D E F G H I Elements in ArrayList2... A B C D E F G H I Is ArrayList1 equal to ArrayList2? = False Elements in ArrayList2 after removing elements in a range... A B C F G H I
示例
让我们看另一个例子-
using System;
using System.Collections;
public class Demo {
public static void Main(String[] args){
ArrayList list1 = new ArrayList();
list1.Add("A");
list1.Add("B");
list1.Add("C");
list1.Add("D");
list1.Add("E");
list1.Add("F");
list1.Add("G");
list1.Add("H");
list1.Add("I");
Console.WriteLine("Elements in ArrayList1...");
foreach (string res in list1){
Console.WriteLine(res);
}
ArrayList list2 = new ArrayList();
list2.Add("One");
list2.Add("Two");
list2.Add("Three");
list2.Add("Four");
list2.Add("Five");
list2.Add("Six");
list2.Add("Seven");
Console.WriteLine("Elements in ArrayList2...");
foreach (string res in list2){
Console.WriteLine(res);
}
list2.RemoveRange(1, 6);
Console.WriteLine("Elements in ArrayList2 after removing elements in a range...");
foreach (string res in list2){
Console.WriteLine(res);
}
}
}输出结果
这将产生以下输出-
Elements in ArrayList1... A B C D E F G H I Elements in ArrayList2... One Two Three Four Five Six Seven Elements in ArrayList2 after removing elements in a range... One
