获取或设置StringCollection中指定索引处的元素，代码如下 −
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]);
Console.WriteLine("Count of strings in StringCollection = " + strCol.Count);
}
}
输出
这将产生以下输出 −
StringCollection elements... A B C D E F G H Element at 5th index = F Count of strings in StringCollection = 8
示例
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();
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
这将产生以下输出 −
StringCollection elements... A B C D E F G H Element at 5th index = F Element at 5th index [UPDATED] = K
