如何检索ComboBox选择的值作为枚举类型？

Question

这是我的Enum代码:

public enum EmployeeType
{
    Manager,
    Worker
}

我将初始化ComboBox值,而表单初始化为

 combobox1.ItemsSource = Enum.GetValues(typeof(EmployeeType));

现在我想找回的选择的值ComboBox作为EmployeeType枚举,而不是字符串或整数等

任何帮助表示赞赏.

Answer 1

EmployeeType selected = (EmployeeType)combobox1.SelectedItem;

您可能希望首先检查null(无选择).

为了完整起见,这是我设置的示例程序.XAML:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition />
        </Grid.RowDefinitions>
        <ComboBox x:Name="_ComboBox" />
        <Button Grid.Row="1" Click="Button_Click" />
    </Grid>
</Window>

和代码隐藏:

using System;
using System.Windows;

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            _ComboBox.ItemsSource = Enum.GetValues(typeof(Whatever));
        }

        public enum Whatever
        {
            One,
            Two,
            Three,
            Four
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            if (_ComboBox.SelectedItem == null)
            {
                MessageBox.Show("No Selection");
            }
            else
            {
                Whatever whatever = (Whatever)_ComboBox.SelectedItem;
                MessageBox.Show(whatever.ToString());
            }
        }
    }
}
