在 C# 中獲取或設定 StringCollection 中指定索引處的元素
要獲取或設定 StringCollection 中指定索引處的元素,程式碼如下 −
示例
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection strCol = new StringCollection(); String[] strArr = new String[] { "A", "B", "C", "D", "E", "F", "G", "H" }; Console.WriteLine("StringCollection elements..."); foreach (string str in strArr) { Console.WriteLine(str); } strCol.AddRange(strArr); Console.WriteLine("Element at 5th index = "+strCol[5]); } }
輸出
此程式碼將產生以下輸出 −
StringCollection elements... A B C D E F G H Element at 5th index = F
示例
我們來看另一個示例 −
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection strCol = new StringCollection(); String[] strArr = new String[] { "A", "B", "C", "D", "E", "F", "G", "H" }; Console.WriteLine("StringCollection elements..."); foreach (string str in strArr) { Console.WriteLine(str); } strCol.AddRange(strArr); Console.WriteLine("Element at 5th index = "+strCol[5]); strCol[5] = "M"; Console.WriteLine("Element at 5th index (updated) = "+strCol[5]); } }
輸出
此程式碼將產生以下輸出 −
StringCollection elements... A B C D E F G H Element at 5th index = F Element at 5th index (updated) = M
