将数组键设置为字符串而不是int？

Question

我试图将数组键设置为字符串,如下例所示,但在C#.

<?php
$array = array();
$array['key_name'] = "value1";
?>

Answer 1

你在C#中最接近的是Dictionary<TKey, TValue>:

var dict = new Dictionary<string, string>();
dict["key_name"] = "value1";

请注意,一个Dictionary<TKey, TValue>是不一样的PHP的关联数组,因为它是唯一的访问由一种类型的键的(TKey-这是string在上述的例子),与串/整数密钥(感谢的帕维尔的组合用于澄清本点).

也就是说,我从未听说过.NET开发人员抱怨过这一点.

回应你的评论:

// The number of elements in headersSplit will be the number of ':' characters
// in line + 1.
string[] headersSplit = line.Split(':');

string hname = headersSplit[0];

// If you are getting an IndexOutOfRangeException here, it is because your
// headersSplit array has only one element. This tells me that line does not
// contain a ':' character.
string hvalue = headersSplit[1];

Answer 2

你可以使用一个Dictionary<TKey, TValue>：

Dictionary<string, string> dictionary = new Dictionary<string, string>();
dictionary["key_name"] = "value1";

Answer 3

嗯我猜你想要一本字典:

using System.Collections.Generic;

// ...

var dict = new Dictionary<string, string>();
dict["key_name1"] = "value1";
dict["key_name2"] = "value2";
string aValue = dict["key_name1"];
