无法将“System.String”类型的 object 转换为“System.Boolean.Net Core MVC”

Question

我参考本教程https://github.com/bhrugen/AppointmentScheduler我做了相同的代码，但我运行它时无法显示获取日历数据，它显示错误 - 无法投射类型为“System.String”的 object键入'System.Boolean。 我的代码是：-

预约ApiController.cs：

[HttpGet]
        [Route("GetCalendarData")]
        public IActionResult GetCalendarData(string doctorId)
        {
            CommonResponse<List<AppointmentVM>> commonResponse = new CommonResponse<List<AppointmentVM>>();
            try
            {
                if (role == Helper.Patient)
                {
                    commonResponse.dataenum = _appointmentService.PatientsEventsById(loginUserId);
                    commonResponse.status = Helper.success_code;
                }
                else if (role == Helper.Doctor)
                {
                    commonResponse.dataenum = _appointmentService.DoctorsEventsById(loginUserId);
                    commonResponse.status = Helper.success_code;
                }
                else
                {
                    commonResponse.dataenum = _appointmentService.DoctorsEventsById(doctorId);
                    commonResponse.status = Helper.success_code;
                }
            }
            catch (Exception e)
            {
                commonResponse.message = e.Message;
                commonResponse.status = Helper.failure_code;
            }
            return Ok(commonResponse);
        }

脚本.js：

var routeURL = location.protocol + "//" + location.host;
$(document).ready(function () {
    $("#appointmentDate").kendoDateTimePicker({
        value: new Date(),
        dateInput: false
    });

    InitializeCalendar();
});
var calendar;
function InitializeCalendar() {
    try {
        var calendarEl = document.getElementById('calendar');
        if (calendarEl != null) {
            calendar = new FullCalendar.Calendar(calendarEl, {
                initialView: 'dayGridMonth',
                headerToolbar: {
                    left: 'prev,next,today',
                    center: 'title',
                    right: 'dayGridMonth,timeGridWeek,timeGridDay'
                },
                selectable: true,
                editable: false,
                select: function (event) {
                    onShowModal(event, null);
                },
                eventDisplay:'block',
                events: function (frtch, successCallback, failureCallback) {
                    $.ajax({
                        url: routeURL + '/api/Appointment/GetCalendarData?doctorId=' + $("#doctorId").val(),
                        type: 'GET',
                        dataType: 'JSON',
                        success: function (response) {
                            var events = [];
                            if (response.status === 1) {
                                $.each(response.dataenum, function (i, data) {
                                    events.push({
                                        title: data.title,
                                        description: data.description,
                                        start: data.startDate,
                                        end: data.endDate,
                                        backgroundColor: "#162466",
                                        textColor: "white",
                                        id: data.id
                                    });
                                })
                            }
                            successCallback(events);
                        },
                        error: function (xhr) {
                            $.notify("Error", "error");
                        }
                    });
                },
                eventClick: function (info) {
                    getEventDetailsByEventId(info.event);
                }
            });
            calendar.render();
        }
    }
    catch (e) {
        alert(e);
    }
}

约会服务.cs：

 public List<AppointmentVM> DoctorsEventsById(string doctorId)
        {
            return _db.Appointments.Where(x => x.DoctorId == doctorId).ToList().Select(c => new AppointmentVM()
            {
                Id = c.Id,
                Description = c.Description,
                StartDate = c.StartDate.ToString("yyyy-MM-dd HH:mm:ss"),
                EndDate = c.EndDate.ToString("yyyy-MM-dd HH:mm:ss"),
                Title = c.Title,
                Duration = c.Duration,
                IsDoctorApproved = c.IsDoctorApproved
            }).ToList();
        }

IAppointmentService.cs：

public List<AppointmentVM> DoctorsEventsById(string doctorId);

Answer 1

无法将类型为“System.String”的 object 转换为类型“System.Boolean”。 您需要确保AppointmentVM中IsDoctorApproved的类型为 bool：

public class AppointmentVM
{
    public bool IsDoctorApproved {get;set;}
}

此外，您需要确保数据库中IsDoctorApproved的类型是 bool。
