声明并初始化数组 −
string[] str = new string[] {
"Cat",
"Mat",
"Rat"
};
现在，使用 IndexOf() 方法查找单词 “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
Our Array = Cat Mat Rat Element Mat found at the following index: 1
