C#程序查找字符串中单词的索引
声明并初始化一个数组-
string[] str = new string[] { "Cat", "Mat", "Rat" };
现在,用ueIndexOf()
方法找到单词“Mat”的索引-
Array.IndexOf(str, "Mat");
以下是代码-
示例
using System; public class Demo { public static void Main() { string[] str = new string[] { "Cat", "Mat", "Rat" }; Console.WriteLine("Our Array ="); for (int i = 0; i < str.Length; i++) { string res = str[i]; Console.WriteLine(res); } int findIndex = Array.IndexOf(str, "Mat"); Console.Write("Element Mat found at the following index: "); Console.WriteLine(findIndex); } }
输出结果
Our Array = Cat Mat Rat Element Mat found at the following index: 1
