ContractNamespaceAttribute Class


Specifies the CLR namespace and XML namespace of the data contract.

public ref class ContractNamespaceAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Module, AllowMultiple=true, Inherited=false)]
public sealed class ContractNamespaceAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Module, AllowMultiple=true, Inherited=false)>]
type ContractNamespaceAttribute = class
    inherit Attribute
Public NotInheritable Class ContractNamespaceAttribute
Inherits Attribute


The following example shows the ContractNamespaceAttribute applied to an assembly.

[assembly: ContractNamespaceAttribute("",
    ClrNamespace = "Microsoft.Contracts.Examples")]
namespace Microsoft.Contracts.Examples
    public class Person
        internal string FirstName;
        internal string LastName;
<assembly: ContractNamespaceAttribute("", _
   ClrNamespace := "Microsoft.Contracts.Examples")>

Namespace Microsoft.Contracts.Examples
    <DataContract()>  _
    Public Class Person
        <DataMember()>  _
        Friend FirstName As String
        <DataMember()>  _
        Friend LastName As String
    End Class 
End Namespace


Apply the ContractNamespaceAttribute attribute to an assembly that contains types to which the DataContractAttribute has been applied. The ContractNamespaceAttribute enables you to set a namespace that is different than the one generated when the type is serialized. For more information about how names are generated, see Data Contract Names.

If you are using a type to conform to an existing data contract, you must match the namespace of the existing contract by using the ContractNamespaceAttribute (or the Namespace property of the DataContractAttribute class).


In any code, you can use the word ContractNamespace instead of the longer ContractNamespaceAttribute.



Initializes a new instance of the ContractNamespaceAttribute class using the supplied namespace.



Gets or sets the CLR namespace of the data contract type.


Gets the namespace of the data contract members.


When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)



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)

Creates a shallow copy of the current Object.

(Inherited from Object)

Returns a string that represents the current object.

Explicit Interface Implementations

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

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_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)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.
