方法一：

绑定

[csharp] view plain copy

enum TestEnum {zero=0,one=1,two=2}
ComboBox cbo = new ComboBox();
cbo.DataSource = System.Enum.GetNames(typeof(TestEnum));
TestEnum test = TestEnum .one;
cbo.SelectedIndex = this.cbo.FindString(test.ToString());
取值
TestEnum testenum = (TestEnum)Enum.Parse(typeof(TestEnum) ,cbo.SelectedItem.ToString() ,false)

方法二：

[csharp] view plain copy

foreach (var v in typeof(AA).GetFields())
{
if (v.FieldType.IsEnum == true)
{
this.comboBox1.Items.Add(v.Name);
}
}
this.comboBox1.SelectedIndex = 1;

方法三：

反射,枚举,绑定下拉框

[csharp] view plain copy

public static class EnumManager<TEnum>
{
private static DataTable GetDataTable()
{
Type enumType = typeof(TEnum); // 获取类型对象
FieldInfo[] enumFields = enumType.GetFields(); //获取字段信息对象集合
DataTable table = new DataTable();
table.Columns.Add("Name", Type.GetType("System.String"));
table.Columns.Add("Value", Type.GetType("System.Int32"));
//遍历集合
foreach (FieldInfo field in enumFields)
{
if (!field.IsSpecialName)
{
DataRow row = table.NewRow();
row[0] = field.Name; // 获取字段文本值
row[1] = Convert.ToInt32(field.GetRawConstantValue()); // 获取int数值
//row[1] = (int)Enum.Parse(enumType, field.Name); 也可以这样
table.Rows.Add(row);
}
}
return table;
}
public static void SetListControl(ListControl list)
{
list.DataSource = GetDataTable();
list.DataTextField = "Name";
list.DataValueField = "Value";
list.DataBind();
}
}
public enum BookingStatus {
未提交 = 1,
已提交,
已取消,
已完成 = 6
}
EnumManager<BookingStauts>.SetListControl(ddlBookingStatus);
EnumManager<TicketStatus>.SetListControl(rblTicketStatus);
