wpf没有NumericUpDown这个控件，只有自己写，或找别人写好的，作为初学者，肯定自己写了

xmal页面，包括1个label， 2gebutton，1个textbox

<Grid Margin="10">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <Label Name="labelName"  Grid.Row="0" Grid.Column="0" Margin="5,10" Foreground="White" FontSize="20" />
        <StackPanel Grid.Row="0" Grid.Column="1" Orientation="Horizontal">
            <Button Name="plusBtn" Content=" + " Margin="5,10" Click="plusBtnClick" FontSize="20" />
            <TextBox Name="numbericTxt" Text="0"   Margin="5,10" Width="50" HorizontalContentAlignment="Center"  VerticalContentAlignment="Center" TextChanged="NumbericTxtTextChanged" GotFocus="NumbericTxtGotFocus" />
            <Button Name="reduceBtn" Content=" - " Margin="5,10" Padding="5,0" Click="reduceBtnClick" FontSize="20" />
        </StackPanel>
    </Grid>

        public NumericUpDownControl()
        {
            InitializeComponent();
        }

        /// <summary>
        /// label 显示内容
        /// </summary>
        public string LabeContent
        {
            get { return GetValue(LabeContentProperty).ToString(); }
            set { SetValue(LabeContentProperty, value);  }
        }

        /// <summary>
        /// 最小值
        /// </summary>
        public float MinValue
        {
            get { return Convert.ToSingle(GetValue(MinValueProperty)); }
            set { SetValue(MinValueProperty,
