This is my js.

$('#tablaDemo').DataTable({
            processing: true,
            serverSide: true,
            ajax: {
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "../Paginas/Crmedu_LstCliente.aspx/getDemo",
                data: function (d) {
                    console.log(d);
                    return JSON.stringify({ parameters: d , dato: "{value: 'Vitmar'}", midat: "Hola mundo"});
                }
            }
        });

and this is my method.

public static void getDemo(object parameters, object dato, string midat)
    {
       log.Info(String.Format("FORMAT REQ ========== >>>"+midat)); 
       //Request
       //var req = DataTableParameters.Get(parameters);
}

as I collect in value of dato , without having to create models or something like that, forget about the parameters.

for example midat if the value arrives. But from the json?

It's like david_rprada, the only thing I would add is that I recommend you to create specific types to receive in your controllers and not just objects, .NET will be responsible for de-serializing them correctly for you.

Because the variable City1 does not save the value in the first execution of the modal, and on the contrary in the second execution if it does Laravel 5.3 Eloquent Union Error

Asp.Net does a great job mapping serialized JSON parameters into .NET types, so it is unnecessary to double-serialize your JSON object by calling JSON.stringify

.NET already correctly performs data mapping by convention.

To access the data of a JSON object:

var data = {key1: 'value1', key2: 'value2'};

In your getDemo method you would declare the parameter as Dictionary<string, object> data

That way you can access its properties:

string key1 = data["key1"].ToString();
