如何在C#中创建StringCollection？
要在C#中创建StringCollection，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);
}
}输出结果
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
现在让我们来看另一个示例-
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main(){
StringCollection stringCol = new StringCollection();
String[] arr = new String[] { "100", "200", "100", "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.Remove("100");
Console.WriteLine("Total number of elements now = "+stringCol.Count);
}
}输出结果
这将产生以下输出-
Array elements... 100 200 100 400 500 Total number of elements = 5 Total number of elements now = 4
