WPF的DataGrid控件DataGridComboBoxColumn三种binding形式

// View中代码
<DataGridComboBoxColumn x:Name="comboBoxDev" Header="类型" ItemsSource="{Binding DeviceType}" DisplayMemberPath="{Binding DName}" SelectedValuePath="{Binding DValue}"/>

// View后台代码
this.DataContext = new ViewModel();

// ViewModel中代码
public List<string> DeviceType { get; set; } = new() { "平移台", "旋转台", "不使用", };

// View代码
                <DataGridComboBoxColumn x:Name="comboBoxDev" Header="类型" ItemsSource="{Binding DeviceType}" DisplayMemberPath="{Binding DName}" SelectedValuePath="{Binding DValue}"/>

// View后台代码
DeviceType = new List<string>
            {
                "平移台",
                "旋转台",
                "不使用",
            };

            this.comboBoxDev.ItemsSource = DeviceType;

  // View代码
xmlns:vm="clr-namespace:MainPro.ViewModels" 

              <DataGridComboBoxColumn x:Name="comboBoxDev" Header="类型" ItemsSource="{Binding Source={x:Static vm:ViewModel.DeviceType}}" DisplayMemberPath="{Binding DName}" SelectedValuePath="{Binding DValue}"/>

// ViewModel代码
public static List<string> DeviceType { get; set; } = new() { "平移台", "旋转台", "不使用", };

// View代码
<Window.Resources>
        <x:Array x:Key="DeviceTypeArray" Type="sys:String">
            <sys:String>平移台</sys:String>
            <sys:String>旋转台</sys:String>
            <sys:String>不使用</sys:String>
        </x:Array>
    </Window.Resources>

                <DataGridComboBoxColumn x:Name="comboBoxDev" Header="类型" ItemsSource="{StaticResource DeviceTypeArray}" DisplayMemberPath="{Binding DName}" SelectedValuePath="{Binding DValue}"/>
