在C#中将对象添加到Collection的末尾
要将对象添加到Collection的末尾，代码如下-
示例
using System;
using System.Collections.ObjectModel;
public class Demo {
public static void Main() {
Collection<int> col = new Collection<int>();
col.Add(10);
col.Add(20);
col.Add(30);
col.Add(40);
col.Add(50);
col.Add(60);
col.Add(70);
col.Add(80);
Console.WriteLine("Elements in the Collection...");
foreach(int val in col) {
Console.WriteLine(val);
}
Console.WriteLine("Does the collection has the element 70? = "+col.Contains(70));
Console.WriteLine("Count of elements = " + col.Count);
}
}输出结果
这将产生以下输出-
Elements in the Collection... 10 20 30 40 50 60 70 80 Does the collection has the element 70? = True Count of elements = 8
示例
让我们看另一个例子-
using System;
using System.Collections.ObjectModel;
public class Demo {
public static void Main() {
Collection<int> col = new Collection<int>();
col.Add(10);
col.Add(20);
col.Add(30);
col.Add(40);
col.Add(50);
col.Add(60);
col.Add(70);
col.Add(80);
Console.WriteLine("Elements in the Collection...");
foreach(int val in col) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements = " + col.Count);
col.Add(100);
col.Add(150);
col.Add(200);
Console.WriteLine("Elements in the Collection...UPDATED");
foreach(int val in col) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements...UPDATED = " + col.Count);
}
}输出结果
这将产生以下输出-
Elements in the Collection... 10 20 30 40 50 60 70 80 Count of elements = 8 Elements in the Collection...UPDATED 10 20 30 40 50 60 70 80 100 150 200 Count of elements...UPDATED = 11
