我不能在mvc核心中使用ajax post作为Json Formatting从动作中获取对象

 $(document).on("click", "#StudentDelete", function () {
        var Id = $(this).attr("data-id");
        alert(gelenId);
        $.ajax({
            url: '/SchoolRepo/DeleteStudent/' + Id,
            type: "POST",
            datatype: "Json",
            success: function (response) {
                if (response.Success) {
                    location.reload();
                    alert(response.Message);
                }
                else {
                    alert(response.Message);
                }
            }
        });

    });

public class ResultJson
{
    public bool Success { get; set; }
    public string Message { get; set; }
}

 public IActionResult DeleteStudent(int id)
    {
        var student = db.Students.FirstOrDefault(q => q.Id == id);
        if (student!=null)
        {
            db.Students.Remove(student);
            db.SaveChanges();
            return Json(new  ResultJson { Message = "Student is deleted successfully", Success=true });
        }
        return Json(new ResultJson { Message = "Student is not deleted", Success = false });
    }

when I use these code snappets I can't get 'Response.Message' or 'Response.Success' values. always returned 'undefined'. when I used the same codes in mvc 5 I could get values. what is the reason ? thank you in advance

当我使用这些代码时，我无法获得'Response.Message'或'Response.Success'值。总是返回'undefined'。当我在mvc 5中使用相同的代码时，我可以得到值。是什么原因？先谢谢你

JSON result in ASP.NET Core MVC is using camel case naming strategy by default while serializing the result. So the result will get returned as shown below.

ASP.NET Core MVC中的JSON结果在序列化结果时默认使用驼峰式命名策略。因此结果将返回，如下所示。

{"success":true,"message":"Student is deleted successfully"}

{“success”：true，“message”：“学生已成功删除”}

You can access the result as response.success and response.message

您可以将结果作为response.success和response.message访问

I hope this help you.

我希望这对你有帮助。
