从 C# 的 StringCollection 中的指定索引处移除
从 StringCollection 的指定索引处移除的代码如下 −
示例
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection stringCol = new StringCollection(); String[] arr = new String[] { "100", "200", "300", "400", "500" }; Console.WriteLine("Array elements..."); foreach (string res in arr) { Console.WriteLine(res); } stringCol.AddRange(arr); Console.WriteLine("Total number of elements = "+stringCol.Count); stringCol.RemoveAt(3); Console.WriteLine("Total number of elements now = "+stringCol.Count); } }
输
这将生成以下输出 −
Array elements... 100 200 300 400 500 Total number of elements = 5 Total number of elements now = 4

让我们看另一个示例 −
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection stringCol = new StringCollection(); String[] arr = new String[] { "A", "B", "C", "D", "E" }; Console.WriteLine("Array elements..."); foreach (string res in arr) { Console.WriteLine(res); } stringCol.AddRange(arr); Console.WriteLine("Total number of elements = "+stringCol.Count); stringCol.RemoveAt(1); stringCol.RemoveAt(2); Console.WriteLine("Total number of elements now = "+stringCol.Count); } }
输
这将生成以下输出 −
Array elements... A B C D E Total number of elements = 5 Total number of elements now = 3
