在C#中的指定索引处将元素插入到集合Collection中
要将元素插入到指定索引处的Collection中,代码如下-
示例
using System;using System.Collections.ObjectModel;
public class Demo {
public static void Main(){
Collection<string> col = new Collection<string>();
col.Add("Laptop");
col.Add("Desktop");
col.Add("Notebook");
col.Add("Ultrabook");
col.Add("Tablet");
col.Add("Headphone");
col.Add("Speaker");
Console.WriteLine("Elements in Collection...");
foreach(string str in col){
Console.WriteLine(str);
}
Console.WriteLine("Element at index 3 = " + col[3]);
Console.WriteLine("Element at index 4 = " + col[4]);
col.Insert(5, "Alienware");
Console.WriteLine("Elements in Collection...UPDATED");
foreach(string str in col){
Console.WriteLine(str);
}
}
}
输出结果
这将产生以下输出-
Elements in Collection...Laptop
Desktop
Notebook
Ultrabook
Tablet
Headphone
Speaker
Element at index 3 = Ultrabook
Element at index 4 = Tablet
Elements in Collection...UPDATED
Laptop
Desktop
Notebook
Ultrabook
Tablet
Alienware
Headphone
Speaker
示例
现在让我们来看另一个示例-
using System;using System.Collections.ObjectModel;
public class Demo {
public static void Main(){
Collection<string> col = new Collection<string>();
col.Add("Andy");
col.Add("Kevin");
col.Add("John");
col.Add("Kevin");
col.Add("Mary");
col.Add("Katie");
col.Add("Barry");
col.Add("Nathan");
Console.WriteLine("Elements in Collection...");
foreach(string str in col){
Console.WriteLine(str);
}
col.Insert(3, "Jacob");
Console.WriteLine("Elements in Collection...UPDATED");
foreach(string str in col){
Console.WriteLine(str);
}
}
}
输出结果
这将产生以下输出-
Elements in Collection...Andy
Kevin
John
Kevin
Mary
Katie
Barry
Nathan
Elements in Collection...UPDATED
Andy
Kevin
John
Jacob
Kevin
Mary
Katie
Barry
Nathan
