Convert a list to a JSON object utilizing the Json.NET library

I am using json.net to convert currency rates to JSON format.

In the C# entity, there are Name and Value properties; where Name represents currencies like USD, GBP, etc. and Value holds the currency rate.

Since I do not know the index of different currencies, I want to retrieve a currency in JavaScript by simply declaring var a = obj["USD"]; instead of iterating through an array to find array[i].name == "USD". The default output of

JsonConvert.SerializeObject(currencyList);
is as follows:

[
    {"name": "one",   "pId": "foo1", "cId": "bar1"},
    {"name": "two",   "pId": "foo2", "cId": "bar2"},
    {"name": "three", "pId": "foo3", "cId": "bar3"}
]

However, I would prefer the output to be structured like this:

{
    "one":   {"pId": "foo1", "cId": "bar1"},
    "two":   {"pId": "foo2", "cId": "bar2"},
    "three": {"pId": "foo3", "cId": "bar3"}
}

I am wondering if it is possible to achieve this formatting using json.net, or if I need to create my own parser?

Answer №1

To begin, it is necessary to construct a dictionary:

Create a Dictionary<String, YourType> object = list.ToDictionary(item => item.name);

Make sure to substitute YourType with the appropriate data type for your entity.

Afterwards, you can easily serialize the dictionary into JSON format.
