The above is an enumeration list. How can I read it? What about binding with a DDR?Copy codeThe Code is as follows: ddlType. DisplayMember = "Value ";
DdlType. ValueMember = "Key ";
DdlType. DataSource = CommonFunctions. GetEnumItems (typeof (AppEnum. PointLogType), false );
DdlType. SelectedValue = 25; // Default Value

The GetEnumItems method in CommonFunctions is as follows:Copy codeThe Code is as follows: // <summary>
/// Obtain the list of all items contained in the enumerated type.
/// </Summary>
/// <Param name = "enumType"> Enumeration type </param>
/// <Param name = "withAll"> include "All" </param>
/// <Returns> </returns>
Public static List <EnumItem> GetEnumItems (Type enumType, bool withAll)
{
List <EnumItem> list = new List <EnumItem> ();

If (enumType. IsEnum! = True)
{
// Not an enumeration type
Throw new InvalidOperationException ();
}

// Contains the All option
If (withAll = true)
List. Add (new EnumItem (AppConst. IntNull, "All "));

// Obtain the type information of the feature Description
Type typeDescription = typeof (DescriptionAttribute );

// Obtain the enumerated field information (because the enumerated value is actually a static field value)
System. Reflection. FieldInfo [] fields = enumType. GetFields ();

// Retrieve all fields
Foreach (FieldInfo field in fields)
{
// Filter out one that is not an enumeration value and records the enumerated source type.
If (field. FieldType. IsEnum = false)
Continue;

// Obtain the enumerated value through the field name
Int value = (int) enumType. InvokeMember (field. Name, BindingFlags. GetField, null, null );
String text = string. Empty;

// Obtain all the custom features of this field. Only the Description feature is available here.
Object [] arr = field. GetCustomAttributes (typeDescription, true );
If (arr. Length> 0)
{
// Because the custom Description feature cannot be repeated, only the first one is used.
DescriptionAttribute aa = (DescriptionAttribute) arr [0];

// Obtain the description of the feature
Text = aa. Description;
}
Else
{
// If there is no feature description, the field name in English is displayed.
Text = field. Name;

List. Add (new EnumItem (value, text ));
