View界面綁定：
ItemsSource數據源爲字典數據
DisplayMemberPath="Value" 爲顯示字典數據的值
SelectedValuePath="Key"字典數據的鍵與SelectedValue類型對應
<ComboBox Grid.Row="8" Grid.Column="1" ItemsSource="{Binding selGroupList}" SelectedIndex="0" SelectedValuePath="Key" DisplayMemberPath="Value" SelectedValue="{Binding Group,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" HorizontalAlignment="Left" Width="252" Height="25" IsEditable="True" Margin="5,3"></ComboBox>
界面效果：
念念不忘，必有迴響。技術成就夢想！
