要在 StringCollection 中将字符串插入到指定索引处，代码如下 −
示例
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
StringCollection strCol = new StringCollection();
strCol.Add("Accessories");
strCol.Add("Books");
strCol.Add("Electronics");
Console.WriteLine("StringCollection elements...");
foreach (string res in strCol){
Console.WriteLine(res);
}
strCol.Insert(2, "Headphone");
Console.WriteLine("StringCollection elements...UPDATED");
foreach (string res in strCol){
Console.WriteLine(res);
}
}
}
输出
这将产生以下输出 −
StringCollection elements... Accessories Books Electronics StringCollection elements...UPDATED Accessories Books Headphone Electronics
示例
现在让我们看另一个例子 −
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
StringCollection strCol = new StringCollection();
strCol.Add("Laptop");
strCol.Add("Desktop");
strCol.Add("Tablet");
strCol.Add("Speakers");
Console.WriteLine("StringCollection elements...");
foreach (string res in strCol){
Console.WriteLine(res);
}
strCol.Insert(2, "Headphone");
strCol.Insert(3, "Alienware");
Console.WriteLine("StringCollection elements...UPDATED");
foreach (string res in strCol){
Console.WriteLine(res);
}
strCol.Insert(4, "E-Book Reader");
strCol.Insert(5, "Monitor");
strCol.Insert(6, "HDD");
strCol.Insert(7, "SSD");
Console.WriteLine("StringCollection elements...UPDATED");
foreach (string res in strCol){
Console.WriteLine(res);
}
}
}
输出
这将产生以下输出 −
StringCollection elements... Laptop Desktop Tablet Speakers StringCollection elements...UPDATED Laptop Desktop Headphone Alienware Tablet Speakers StringCollection elements...UPDATED Laptop Desktop Headphone Alienware E-Book Reader Monitor HDD SSD Tablet Speakers
