字符串在数组中吗? [英] Is string in array?

问题描述

查看 string[] 是否包含元素的最佳方法是什么.这是我第一次尝试.但也许我忽略了一些东西.数组大小不超过 200 个元素.

What would be the best way to look in a string[] to see if it contains a element. This was my first shot at it. But perhaps there is something that I am overlooking. The array size will be no larger than 200 elements.

bool isStringInArray(string[] strArray, string key)
{
    for (int i = 0; i <= strArray.Length - 1; i++)
        if (strArray[i] == key)
            return true;
    return false;
}

推荐答案

只需使用已经内置的 Contains() 方法:

Just use the already built-in Contains() method:

using System.Linq;

//...

string[] array = { "foo", "bar" };
if (array.Contains("foo")) {
    //...
}
