我有一个带有空代码隐藏文件的wpf文件(如果可能,我想保持代码隐藏为空)

然后我有了这个viewmodel文件

using System;
using System.Collections.ObjectModel;
using System.Windows.Input;
using MVVM_Test.Model;
using MvvmFoundation.Wpf;

namespace MVVM_Test.ViewModel
{
    public class ViewModel : ObservableObject
    {
        private DateTime selectedDate;
        public DateTime SelectedDate
        {
            get
            {
                return selectedDate;
            }
            set
            {
                selectedDate = value;
                RaisePropertyChanged("SelectedDate");
            }
        }

        private DateTime startDate;
        public DateTime StartDate
        {
            get { return startDate; }
            set
            {
                startDate = value;
                RaisePropertyChanged("StartDate");
            }
        }

        private DateTime endDate;
        public DateTime EndDate
        {
            get { return endDate; }
            set
            {
                endDate = value;
                RaisePropertyChanged("EndDate"); …
