C#的String.Chars []属性示例
C#String.Chars[]属性
要从字符串访问元素/字符,我们使用String.Chars[]属性,就像C,C++和其他编程语言一样–我们可以从指定的索引访问字符串的字符。
语法:
public char this[int index] { get; }参数:index是必须访问字符的位置,索引的最小值为0,最大值为length-1。
返回值:char–返回一个字符。
示例
Input:
string str = "nhooo";
accessing characters:
str[0]: 'I'
str[1]: 'n'
str[str.Lenght-1]: 'p'C#示例使用String.Chars[]属性打印字符串的字符
using System;
using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
//字符串变量声明
string str = "nhooo";
//打印第一个和最后一个字符
Console.WriteLine("First character is: " + str[0]);
Console.WriteLine("Last character is: " + str[str.Length-1]);
//根据索引打印所有字符
for (int loop = 0; loop < str.Length; loop++)
{
Console.WriteLine("character at {0} index is = {1}", loop, str[loop]);
}
//按ENTER退出
Console.ReadLine();
}
}
}输出结果
First character is: I Last character is: p character at 0 index is = I character at 1 index is = n character at 2 index is = c character at 3 index is = l character at 4 index is = u character at 5 index is = d character at 6 index is = e character at 7 index is = H character at 8 index is = e character at 9 index is = l character at 10 index is = p
