            url: "/Dashboard/filter",
            data: jsonData,
            traditional: true,
            contentType: 'application/json',
            dataType: 'json',
            type: "POST",
            success: function (data) {
                console.error(data);

            },

You can use the following code to send and receive Json in the form of a class

Ajax code is: 

 var data = "{filter :[{IdField: '2', NameField: 'filter item', Check: 1 , SFilter: 'filter search' , TFilter: 'filter text'}]}";
    $.ajax({
        url: '/home/filter',
        dataType: 'json',
        type: 'POST',
        data: data,
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            alert(data);
        },
        error: function () {
            alert("error");
        }
    });

Class:

public class FilterJson
{
    public string IdField { get; set; }
    public string NameField { get; set; }
    public int Check { get; set; }
    public string SFilter { get; set; }
    public string TFilter { get; set; }
}
public class FJson
{
    public List<FilterJson> filter { get; set; }

}

Controller action is:

[HttpPost]
public JsonResult filter(FJson filterjson)
{

    return Json(new { });
}
