比较尴尬微软提供得日历控件不能很好得修改日按钮,导致一些需求完成不了。。。为为了不重复造轮子网上各种找,最后没找到还是自己造轮子吧。目前只完成当月得显示。

先看效果图

技术分享图片

嗯!就是这样子,还没来的及美化。首先界面代码:

"0,0,10,10" Grid.Column="1">
                "20" VerticalAlignment="Top" Text="{Binding NowTime}" />
                "dgDataSource" AutoGenerateColumns="False"  HeadersVisibility="Column"  ItemsSource="{Binding WeekList}"  IsReadOnly="True"   Grid.Row="0" Margin="0,0,0,26">

                        "*" Header="星期一"  >
                                "{Binding Monday}">"*" Header="星期二"  >
                                "{Binding Tuesday}">"*" Header="星期三"  >
                                "{Binding Wednesday}">"*" Header="星期四"  >
                                "{Binding Thursday}">"*" Header="星期五"  >
                                "{Binding Friday}">"*" Header="星期六"  >
                                "{Binding Saturday}">"*" Header="星期天"  >
                                "{Binding Sunday}">

好吧,看看后台计算得代码:

public void CreadDateTimeList(DateTime dt)
        {
            WeekList.Clear();
            var days = dt.GetMothDays();
            NowTime = dt.Year + "" + dt.Month+"";
            var nowday = dt.AddDays(1 - dt.Day);
            int i = 0;
            while (i  days)
            {
                Weeks item = new Weeks();
                while (i  days)
                {
                    var weebel = nowday.AddDays(i).GetDateWeekEl();
                    item.GetType().GetProperty(weebel).SetValue(item, (nowday.Day + i).ToString(), null);
                    i++;
                    if (weebel == "Sunday")
                    {
                        break;
                    }
                }
                WeekList.Add(item);
            }
        }

大概说下,用了内嵌循环,因为一周就7天所以每次判断获取得时间是否是星期天,如果是就再创对象,想得脑壳痛代码就写得很随意,命名也没注意,不如这个“Sunday”应该用个变量命名一下,后期别人看似乎更清晰,嗯!

再勒,用了反射,因为有七个属性,我比较懒懒得用swich case,看着也蛋疼,下面也贴下扩展方法:

/// 
        /// 返回周几
        /// 
        /// 年月日
        /// 
        public static string GetDateWeekEl(this DateTime dt)
        {
            string[] Weeks = new string[] { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };
            return Weeks[Convert.ToInt32(dt.DayOfWeek)];
        }

这个就无须多说,看看定义得每周得类:

public class Weeks : NotifyObj
        {

            #region 一周得时间变量
            /// 
            /// 周一
            /// 
            private string _Monday;
            public string Monday
            {
                get { return _Monday; }
                set
                {
                    if (value != _Monday)
                        _Monday = value;
                    //RaisepertyChanged("Monday");
                }
            }
            /// 
            /// 周二
            /// 
            private string _Tuesday;
            public string Tuesday
            {
                get { return _Tuesday; }
                set
                {
                    if (value != _Tuesday)
                        _Tuesday = value;
                    //RaisepertyChanged("Tuesday");
                }
            }
            /// 
            /// 周三
            /// 
            private string _Wednesday;
            public string Wednesday
            {
                get { return _Wednesday; }
                set
                {
                    if (value != _Wednesday)
                        _Wednesday = value;
                    //RaisepertyChanged("Wednesday");
                }
            }
            /// 
            /// 周四
            /// 
            private string _Thursday;
            public string Thursday
            {
                get { return _Thursday; }
                set
                {
                    if (value != _Thursday)
                        _Thursday = value;
                    // RaisepertyChanged("Thursday");
                }
            }
            /// 
            /// 周五
            /// 
            private string _Friday;
            public string Friday
            {
                get { return _Friday; }
                set
                {
                    if (value != _Friday)
                        _Friday = value;
                    //  RaisepertyChanged("Friday");
                }
            }
            /// 
            /// 周六
            /// 
            private string _Saturday;
            public string Saturday
            {
                get { return _Saturday; }
                set
                {
                    if (value != _Saturday)
                        _Saturday = value;
                    // RaisepertyChanged("Saturday");
                }
            }
            /// 
            /// 周天
            /// 
            private string _Sunday;
            public string Sunday
            {
                get { return _Sunday; }
                set
                {
                    if (value != _Sunday)
                        _Sunday = value;
                    // RaisepertyChanged("Sunday");
                }
            }

            #endregion 一周得日期变量结束
        }

这里继承得NotifyOb类就无须多说,MVVM了解一下,注释掉的事件是因为目前这些字段不需要双向绑定,但是后期要加得预约功能需要加别的值,所以还是继承一下这个类脑壳痛。。。。
