在JSON属性名称中使用点表示法（例如“ payment.token”）

Question

I am working on a script that has to make an API request. Currently, the object to send to the API looks like this:

var request = new
{
    amount = new
    {
        currency = amount.Currency,
        value = amount.Amount
    },
    additionalData = new AdditionalData
    {
        ApplePayToken = paymentToken
    }
};

The issue is, the API expects the following format to receive the additionalData property:

"additionalData":{
    "payment.token": "some-token"
}

I'm using the following code to try to reformat the object above:

internal partial class AdditionalData
{
    [JsonProperty(PropertyName="additionalData.payment.token")]
    public string ApplePayToken { get; set; }
}

How can I get this to work? Right now, the code doesn't seem to change anything about the request object. It generates it like this:

"additionalData":{
    "ApplePayToken": "some-token"
}

Since the rest of your request appears to be an anonymous object, instead of making a class only for AdditionalData , you could just use a Dictionary :

var request = new
{
    amount = new
    {
        currency = amount.Currency,
        value = amount.Amount
    },
    additionalData = new Dictionary<string, object>
    {
        { "payment.token", "some-token" }
    }
};

Since you said you're new to C#, note that I'm using the object initializer pattern for the dictionary, which is equivalent to pre-building the dictionary and assigning it to the anyonymous object's additionalData :

Dictionary<string, object> addtData = new Dictionary<string, object>();
addtData.Add("payment.token", "some-token");

var request = new
{
    amount = new
    {
        currency = amount.Currency,
        value = amount.Amount
    },
    additionalData = addtData
};

Alternatively, you could make all of the classes you need in C#:

class Request
{
    public Amount amount { get; set; }
    public AdditionalData additionalData { get; set; }
}

class Amount
{
    public string currency { get; set; }
    public decimal value { get; set; }
}

class AdditionalData
{
    [JsonProperty("payment.token")]
    public string applePayToken { get; set; }
}
