EnumMemberAttribute Class


Specifies that the field is an enumeration member and should be serialized.

Namespace:   System.Runtime.Serialization
Assembly:  System.Runtime.Serialization (in System.Runtime.Serialization.dll)


[AttributeUsageAttribute(AttributeTargets.Field, Inherited = false, 
	AllowMultiple = false)]
public sealed class EnumMemberAttribute : Attribute


Initializes a new instance of the EnumMemberAttribute class.


Gets whether the P:System.Runtime.Serialization. EnumMemberAttribute.Value has been explicitly set.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


Gets or sets the value associated with the enumeration member the attribute is applied to.


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The EnumMemberAttribute enables fine control of the names of the enumerations as they are serialized.

To use EnumMemberAttribute, create an enumeration and apply the DataContractAttribute attribute to the enumeration. Then apply the EnumMemberAttribute attribute to each member that needs to be in the serialization stream.

Legacy Code Example

The following example shows EnumMemberAttribute applied to members of an enumeration.

private void GetBindingManagerBase()
   /* CustomersToOrders is the RelationName of a DataRelation. 
   Therefore, the list maintained by the BindingManagerBase is the
   list of orders that belong to a specific customer in the 
   DataTable named Customers, found in DataSet1. */
   myBindingManagerBase = 
   this.BindingContext[DataSet1, "Customers.CustomersToOrders"];

   // Adds delegates to the CurrentChanged and PositionChanged events.
   myBindingManagerBase.PositionChanged += 
   new EventHandler(BindingManagerBase_PositionChanged);
   myBindingManagerBase.CurrentChanged +=
   new EventHandler(BindingManagerBase_CurrentChanged);

private void BindingManagerBase_PositionChanged
(object sender, EventArgs e)
   // Prints the new Position of the BindingManagerBase.
   Console.Write("Position Changed: ");

private void BindingManagerBase_CurrentChanged
(object sender, EventArgs e)
   // Prints the new value of the current object.
   Console.Write("Current Changed: ");

private void MoveNext()
   // Increments the Position property value by one.
   myBindingManagerBase.Position += 1;

private void MovePrevious()
   // Decrements the Position property value by one.
   myBindingManagerBase.Position -= 1;

private void MoveFirst()
   // Goes to the first row in the list.
   myBindingManagerBase.Position = 0;

private void MoveLast()
   // Goes to the last row in the list.
   myBindingManagerBase.Position = 
   myBindingManagerBase.Count - 1;
