将枚举类型绑定到WinForms组合框，然后进行设置

comboBox1.Items.AddRange( Enum.GetNames(typeof(Border3DStyle)));

然后将枚举项用作文本：

toolStripStatusLabel1.BorderStyle = (Border3DStyle)Enum.Parse(typeof(Border3DStyle),comboBox1.Text);

public Form1()
{
    InitializeComponent();
    comboBox.DataSource = EnumWithName<SearchType>.ParseEnum();
    comboBox.DisplayMember = "Name";
}

public class EnumWithName<T>
{
    public string Name { get; set; }
    public T Value { get; set; }

    public static EnumWithName<T>[] ParseEnum()
    {
        List<EnumWithName<T>> list = new List<EnumWithName<T>>();

        foreach (object o in Enum.GetValues(typeof(T)))
        {
            list.Add(new EnumWithName<T>
            {
                Name = Enum.GetName(typeof(T), o).Replace('_', ' '),
                Value = (T)o
            });
        }

        return list.ToArray();
    }
}

public enum SearchType
{
    Value_1,
    Value_2
}

这些方法对我都无效，但这个方法有效（并且它还可以为每个枚举值的名称提供更好的描述）。我不确定是由于.net更新还是其他原因，但无论如何我认为这是最佳方式。你需要添加以下引用：

using System.ComponentModel;

enum MyEnum
{
    [Description("Red Color")]
    Red = 10,
    [Description("Blue Color")]
    Blue = 50
}

....

    private void LoadCombobox()
    {
        cmbxNewBox.DataSource = Enum.GetValues(typeof(MyEnum))
            .Cast<Enum>()
            .Select(value => new
            {
                (Attribute.GetCustomAttribute(value.GetType().GetField(value.ToString()), typeof(DescriptionAttribute)) as DescriptionAttribute).Description,
                value
            })
            .OrderBy(item => item.value)
            .ToList();
        cmbxNewBox.DisplayMember = "Description";
        cmbxNewBox.ValueMember = "value";
    }

当您想要访问数据时，请使用以下两行：

        Enum.TryParse<MyEnum>(cmbxNewBox.SelectedValue.ToString(), out MyEnum proc);
        int nValue = (int)proc;

 public static void EnumForComboBox(this ComboBox comboBox, Type enumType)
 {
     var memInfo = enumType.GetMembers().Where(a => a.MemberType == MemberTypes.Field).ToList();
     comboBox.Items.Clear();
     foreach (var member in memInfo)
     {
         var myAttributes = member.GetCustomAttribute(typeof(DescriptionAttribute), false);
         var description = (DescriptionAttribute)myAttributes;
         if (description != null)
         {
             if (!string.IsNullOrEmpty(description.Description))
             {
                 comboBox.Items.Add(description.Description);
                 comboBox.SelectedIndex = 0;
                 comboBox.DropDownStyle = ComboBoxStyle.DropDownList;
             }
         }   
     }
 }

using System.ComponentModel;

public enum CalculationType
{
    [Desciption("LoaderGroup")]
    LoaderGroup,
    [Description("LadingValue")]
    LadingValue,
    [Description("PerBill")]
    PerBill
}

这个方法在组合框项目中显示描述

combobox1.EnumForComboBox(typeof(CalculationType));

comboBox1.DataSource = Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>();

使用selectedItem设置显示的值

comboBox1.SelectedItem = SomeEnum.SomeValue;

    ''' <summary>
    ''' Returns enumeration as a sortable list.
    ''' </summary>
    ''' <param name="t">GetType(some enumeration)</param>
    Public Shared Function GetEnumAsList(ByVal t As Type) As SortedList(Of String, Integer)

        If Not t.IsEnum Then
            Throw New ArgumentException("Type is not an enumeration.")
        End If

        Dim items As New SortedList(Of String, Integer)
        Dim enumValues As Integer() = [Enum].GetValues(t)
        Dim enumNames As String() = [Enum].GetNames(t)

        For i As Integer = 0 To enumValues.GetUpperBound(0)
            items.Add(enumNames(i), enumValues(i))
        Next

        Return items

    End Function

    public enum Colors
    {
        Red = 10,
        Blue = 20,
        Green = 30,
        Yellow = 40,
    }

comboBox1.DataSource = Enum.GetValues(typeof(Colors));

完整源代码...将枚举绑定到Combobox

comboBox1.DataSource = Enum.GetValues(typeof(MyEnum));

comboBox1.SelectedIndex = (int)MyEnum.Something;

comboBox1.SelectedIndex = Convert.ToInt32(MyEnum.Something);

这两个对我都有效，你确定没有其他问题吗？

只使用这种方式进行强制类型转换：

if((YouEnum)ComboBoxControl.SelectedItem == YouEnum.Español)
{
   //TODO: type you code here
}

cbMultiColumnMode.Properties.Items.AddRange(typeof(MultiColumnMode).GetEnumNames());

获取选定的索引：

MultiColumnMode multiColMode = (MultiColumnMode)cbMultiColumnMode.SelectedIndex;

注意：在此示例中，我使用DevExpress组合框，您可以在Win Form组合框中执行相同的操作。
