在 C# 中获取或设置 StringCollection 中指定索引处的元素
要获取或设置 StringCollection 中指定索引处的元素,代码如下 −
范例
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]); Console.WriteLine("Count of strings in StringCollection = " + strCol.Count); } }
输出
这将生成以下输出 −
StringCollection elements... A B C D E F G H Element at 5th index = F Count of strings in StringCollection = 8
范例
让我们看另一个示例 −
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]= "K"; Console.WriteLine("Element at 5th index [UPDATED] = "+strCol[5]); } }
输出
这将生成以下输出 −
StringCollection elements... A B C D E F G H Element at 5th index = F Element at 5th index [UPDATED] = K
