本文介绍了一个WPF应用程序中使用ComboBox控件并实现双向数据绑定的例子。该示例展示了如何通过XAML定义ComboBox，并在视图模型中设置属性以响应选择变化，同时还包括了命令来处理不同选项的选择。

xaml：

xmlns:be="http://schemas.microsoft.com/xaml/behaviors"

xmlns:prism="http://prismlibrary.com/"

viewmodel:

private string _selectedImagingModeForConfig;
public string SelectedImagingModeForConfig
{
get => _selectedImagingModeForConfig;
set => SetProperty(ref _selectedImagingModeForConfig, value);
}

private int _imagingModeIndex = 1;
public int ImagingModeIndex
{
get => _imagingModeIndex;
set => SetProperty(ref _imagingModeIndex, value);
}

private DelegateCommand<object> _imagingModeChangedCommand;
public DelegateCommand<object> ImagingModeChangedCommand =>
_imagingModeChangedCommand ??= new DelegateCommand<object>(ExecuteImagingModeChangedCommand);

private void ExecuteImagingModeChangedCommand(object parameter)
{
string _imagingMode = SelectedImagingModeForConfig;
switch (_imagingMode)
{
case "model1":
break;
case "model2":
break;
case "model3":
break;
case "model4":
break;
case "model5":
break;
}
}
