WPF 自己画日历

Posted 2021-02-05 getmoney

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

嗯！就是这样子，还没来的及美化。首先界面代码：

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

                        <DataGrid.Columns>
                            <DataGridTemplateColumn Width="*" Header="星期一"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Monday}"></TextBlock>
                                            
                                        </StackPanel>
                                        
                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                            <DataGridTemplateColumn Width="*" Header="星期二"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Tuesday}"></TextBlock>

                                        </StackPanel>

                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                            <DataGridTemplateColumn Width="*" Header="星期三"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Wednesday}"></TextBlock>

                                        </StackPanel>

                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                            <DataGridTemplateColumn Width="*" Header="星期四"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Thursday}"></TextBlock>

                                        </StackPanel>

                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                            <DataGridTemplateColumn Width="*" Header="星期五"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Friday}"></TextBlock>

                                        </StackPanel>

                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                            <DataGridTemplateColumn Width="*" Header="星期六"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Saturday}"></TextBlock>

                                        </StackPanel>

                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                            <DataGridTemplateColumn Width="*" Header="星期天"  >
                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <StackPanel>
                                            <TextBlock Text="{Binding Sunday}"></TextBlock>

                                        </StackPanel>

                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>


                            </DataGridTemplateColumn>
                        </DataGrid.Columns>

                    </DataGrid>
                </Grid>
            </GroupBox>

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 + "年" + dt.Month+"月";
            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：

/// <summary>
        /// 返回周几
        /// </summary>
        /// <param name="dt">年月日</param>
        /// <returns></returns>
        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
            /// <summary>
            /// 周一
            /// </summary>
            private string _Monday;
            public string Monday
            {
                get { return _Monday; }
                set
                {
                    if (value != _Monday)
                        _Monday = value;
                    //RaisepertyChanged("Monday");
                }
            }
            /// <summary>
            /// 周二
            /// </summary>
            private string _Tuesday;
            public string Tuesday
            {
                get { return _Tuesday; }
                set

                    if (value != _Tuesday)
                        _Tuesday = value;
                    //RaisepertyChanged("Tuesday");
                }
            }

            /// </summary>
            private string _Wednesday;
            public string Wednesday
            {
                get { return _Wednesday; }
                set
                {
                    if (value != _Wednesday)
                        _Wednesday = value;
                    //RaisepertyChanged("Wednesday");
                }
            }
            /// <summary>
            /// 周四
            /// </summary>
            private string _Thursday;
            public string Thursday
            {
                get { return _Thursday; }
                set
                {
                    if (value != _Thursday)
                        _Thursday = value;
                    // RaisepertyChanged("Thursday");
                }
            }
            /// <summary>
            /// 周五
            /// </summary>
            private string _Friday;
            public string Friday
            {
                get { return _Friday; }
                set
                {
                    if (value != _Friday)
                        _Friday = value;
                    //  RaisepertyChanged("Friday");
                }
            }
            /// <summary>
            /// 周六
            /// </summary>
            private string _Saturday;
            public string Saturday
            {
                get { return _Saturday; }
                set
                {
                    if (value != _Saturday)
                        _Saturday = value;
                    // RaisepertyChanged("Saturday");
                }
            }
            /// <summary>
            /// 周天
            /// </summary>
            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。。。。
