Json.NET create schema for dictionary

I have a class Letter :

public class Letter
{
    public string p1 {get; set;}
    public string p2 {get; set;}
    public List<string> l1 {get; set;}
    public List<string> l2 {get; set;}
}

And i have json file:

{
    "A": 
    {
        "p1": "",
        "p2": "",
        "l1": ["", "", ..., ""],
        "l2": ["", "", ..., ""]
    }
    "B": {...}
    ...
}

For now i deserialize json with Json.NET from NewtonSoft like this:

var alphabet = JsonConvert.DeserializeObject<Dictionary<char, Letter>>(jsonString);

So i can refer to values like this: alphabet["A"]

Now i want to check, is jsonString, which i want to deserialize is valid.

I found some examples how to read JsonSchema from file, or how to generate it in code. But i can't find out, how generate shema for my example of json file.

Can anyone help me?

P.S.

For now i do it like this. Is this best way?

...
var schemaGenerator = new JSchemaGenerator();
var schemaForLetter = schemaGenerator.Generate(typeof (Letter));
var schema = new JSchema
{
    Type = JSchemaType.Object,
    Properties =
    {
        { "A", schemaForLetter },
        { "B", schemaForLetter },
        ...
    }
}
...

You can generate schema from the type you're deserializing to. For example:

var schema = generator.Generate(typeof(Dictionary<string, Letter>))
