将 DataGridComboBoxColumn 绑定到 class 中声明的枚举

Question

我有一个绑定到我的数据库的数据网格：我希望性别列是一个组合框，其选定值来自数据库。性别是成员内部的枚举 class:

namespace Elysium.model
{ 
    class Member
    {
        public enum MemberType { Standard, Premium }
        public enum Status { Inactive, Active }
        public enum Gender { Male, Female }

我尝试通过以下方式绑定它，但它给了我一个错误，即命名空间中没有定义性别，或者当我这样做时不允许嵌套 <x:Type TypeName="local.Member:Gender" ></x:Type> :

<ObjectDataProvider x:Key="genderEnum" MethodName="GetValues" ObjectType="{x:Type LocalValueEnumerator}">
        <ObjectDataProvider.MethodParameters>
            <x:Type TypeName="local:Gender" ></x:Type>
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>

ViewMembers.xaml:

<Grid DataContext="{StaticResource memberViewSource}">
    <DataGrid x:Name="memberDataGrid" AutoGenerateColumns="False" EnableRowVirtualization="True" ItemsSource="{Binding}" RowDetailsVisibilityMode="VisibleWhenSelected" Width="1100" Height="600">
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="memberIDColumn" Binding="{Binding MemberID}" Header="Member ID" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Name}" Header="Name" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="fatherNameColumn" Binding="{Binding FatherName}" Header="Father Name" Width="SizeToHeader"/>
            <DataGridComboBoxColumn x:Name="genderColumn" SelectedValueBinding="{Binding Value}" Header="Gender" Width="SizeToHeader"/>

ViewMembers.xaml.cs:

public partial class ViewMembers : Page
{
    DataTable memberTable = new DataTable();

    public ViewMembers()
    {
        InitializeComponent();
        MemberDatabase members = MemberDatabase.getApplicationDatabase();
        memberTable = members.getAllMembers();
        memberDataGrid.ItemsSource = memberTable.DefaultView;
    }

ObjectType 应设置为 System.Enum:

<ObjectDataProvider x:Key="genderEnum" 
                    xmlns:sys="clr-namespace:System;assembly=mscorlib"
                    MethodName="GetValues" ObjectType="{x:Type sys:Enum}">
    <ObjectDataProvider.MethodParameters>
        <x:Type TypeName="local:Gender" />
    </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>

用法：

<DataGridComboBoxColumn x:Name="genderColumn"
                        ItemsSource="{Binding Source={StaticResource genderEnum}}" ... />
