您能否拥有一个包含破折号的属性名称 [英] Can you have a property name containing a dash

问题描述

是否可以创建一个属性名称包含破折号的对象?

Is it possible to create an object with a property name that contains a dash character?

我正在创建一个匿名对象，以便可以使用Json.Net将其序列化为Json，并且我需要的属性之一包含一个'-'破折号.

I am creating an anonymous object so that I can serialize it to Json using Json.Net and one of the properties I need contains a '-' dash character.

我想要的一个例子是:

var document =  {
    condtions = new {
        acl = "public-read",
        bucket = "s3-bucketname",
        starts-with = "test/path"
    }
};

我知道我可以在创建对象时用下划线替换短划线，然后在序列化的字符串中替换短划线，但是我想知道如果没有这种解决方法，是否有一种语言可以做到这一点.

I know I could replace the dash with underscores when creating the object and then replace them in the serialized string afterwards, but wanted to know if there is a way in the language to do this without this workaround.

推荐答案

您不能对匿名对象执行此操作；字段名称必须是有效的标识符.您可以改用Dictionary，Json.Net应该使用Dictionary来像匿名对象一样轻松地进行序列化:

You can't do this with anonymous objects; field names must be valid identifiers. You could instead use a Dictionary, which Json.Net should serialise just as easily as an anonymous object:

var document = new {
    conditions = new Dictionary<string, string>() {
        { "acl", "public-read" },
        { "bucket", "s3-bucketname" },
        { "starts-with", "test/path" }
    }
};
