Question

我在FSharp中创建了一个类，如下所示：

type Account() = class
    let mutable amount = 0m
    let mutable number = 0
    let mutable holder = ""

    member this.Number
        with get () = number
        and set (value) = number <- value

    member this.Holder
        with get () = holder
        and set (value) = holder <- value

    member this.Amount
        with get () = amount
        and set (value) = amount <- value

end

当我从像我这样的C＃WebAPI / MVC应用程序中引用项目时

[HttpGet]
public Account Index()
{
    var account = new Account();
    account.Amount = 100;
    account.Holder = "Homer";
    account.Number = 1;
    return account;
}

我得到以下结果。请注意，字段名称是camelCased。

<Account xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/ChickenSoftware.MVCSerializationIssue">
<amount>100</amount>
<holder>Homer</holder>
<number>1</number>
</Account>

当我在C＃中创建类似的类

时

public class NewAccount
{
    public int Number { get; set; }
    public String Holder { get; set; }
    public int Amount { get; set; }
}

输出是Pascal cased

<NewAccount xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/ChickenSoftware.MVCSerializationIssue.Api.Models">
<Amount>100</Amount>
<Holder>Homer</Holder>
<Number>1</Number>
</NewAccount>

我首先想到的是Json Serializer（默认情况下我认为是Newtonsoft），但是当我在控制器中休息时，我看到C＃类只公开了它的公共属性，并且F＃类同时具有属性并暴露了支持领域。我试图添加一个＆＃34;私人＆＃34; F＃let语句的关键字，但我得到了这个：

Error   1   Multiple visibility attributes have been specified for this identifier. 'let' bindings in classes are always private, as are any 'let' bindings inside expressions.

那么F＃类是否可以像Web Api一样对待C＃？

在F＃中创建的类在C＃Web Api / MVC项目中错误地序列化
