像这样使用C#数组myArray ["Name"] ="Some Name"； [英] Using C# Arrays like this myArray["Name"] = "Some Name"

问题描述

我是C#编程的新手，所以如果这是愚蠢的问题，请原谅我，但是我已经在Google上搜索了，但找不到答案.
我的问题是我想以这种方式使用数组:
myArray["Name"] = "Some Name";
然后得到这样的值:
varName = myArray["Name"];

我曾经在PHP中做到这一点，但在C#中却没有.
有人可以帮我吗?

提前谢谢.
最好的问候.

Hi, i''m new in C# programming, so please forgive me if this is stupid question but i''ve searching on google and i can''t find the answer.
My issue is that i want to use an array in this way:
myArray["Name"] = "Some Name";
and then get the value like this:
varName = myArray["Name"];

I used to do that in PHP, but in C# don''t.
Can anybody give me a hand on this?

Thanks in advance.
Best regards.

推荐答案

您可以使用字典.这里是一个例子:

使用System.Collections.Generic;

字典< string，> temp =新字典< string，>();

如果(temp.ContainsKey("Name"))
temp.Remove("Name");

temp ["Name"] =某些名称";
MessageBox.Show(temp ["Name"]);

you can use dictionary. Here, is an example :

using System.Collections.Generic;

Dictionary<string,> temp = new Dictionary<string,>();

if (temp.ContainsKey("Name"))
temp.Remove("Name");

temp["Name"] = "Some Name";
MessageBox.Show(temp["Name"]);

这是不可能的.
数组不能像这样使用.
如果要通过字符串而不是数字编制索引，则必须使用其他方法:
1.索引器(公共字符串this [string key] {get; set;} );
2. A Dictionary<string,>;
3. A StringDictionary;
4. A HashTable;
5.您自己的实现.

This is not possible.
Arrays can''t be used like this.
If you want to index by string instead of number, you have to use something else:
1. An indexer (public string this[string key] { get; set; });
2. A Dictionary<string,>;
3. A StringDictionary;
4. A HashTable;
5. Your own implementation.

如果愿意创建自定义集合类，则可以这样做.不过，使用Dictionary可能会更容易(更快).

You could do it that way, if you''re willing to create a custom collection class. It would probably be easier (and faster) to use a Dictionary, though.
