问题描述
我在寻找存放一些客户数据在内存中,我想这样做是使用一组记录的最佳方式。我不知道这是它在C#什么叫,但基本上我就能够调用客户(我).Name点
并有客户名称作为字符串返回。在图灵,其做过这样的:
I'm looking to store some customer data in memory, and I figure the best way to do that would be to use an array of records. I'm not sure if that's what its called in C#, but basically I would be able to call Customer(i).Name
and have the customers name returned as a string. In turing, its done like this:
type customers :
record
ID : string
Name, Address, Phone, Cell, Email : string
//Etc...
end record
我已经搜查,但我似乎无法找到一个相当于C#。可能有人点我在正确的方向?
I've searched, but I can't seem to find an equivalent for C#. Could someone point me in the right direction?
谢谢! :)
推荐答案
好了,好了这将是一个类
在C#中定义的,所以它可能是这样的:
Okay, well that would be defined in a class
in C#, so it might look like this:
public class Customer
{
public string ID { get; set; }
public string Name { get; set; }
public string Address { get; set; }
public string Phone { get; set; }
public string Cell { get; set; }
public string Email { get; set; }
}
然后,你可以有一个名单,其中,T>
那些:
var customers = new List<Customer>();
customers.Add(new Customer
{
ID = "Some value",
Name = "Some value",
...
});
然后你可以,如果你想通过索引来访问这些:
and then you could access those by index if you wanted:
var name = customers[i].Name;
更新:按 psibernetic
,在 记录
类F#提供了实地平等出了大门,而不是引用平等。这是一个非常重要的区别。为了获得在C#中同样平等的操作,你就需要让这个类
A 结构
,然后需要生产经营者是否相等;一个很好的例子,被发现是在这个问题上What需要在一个结构,以确保平等被重写可以正常运行?。
UPDATE: as stated by psibernetic
, the Record
class in F# provides field level equality out of the gate rather than referential equality. This is a very important distinction. To get that same equality operation in C# you'd need to make this class
a struct
and then produce the operators necessary for equality; a great example is found as an answer on this question What needs to be overriden in a struct to ensure equality operates properly?.
