Public method Supported by Portable Class Library Equals Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected method Supported by Portable Class Library Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method Supported by Portable Class Library GetHashCode Returns the hash code for this instance. (Inherited from Attribute.)
Public method Supported by Portable Class Library GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttribute When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)

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).

Note Note

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

The following example shows the ContractNamespaceAttribute applied to an assembly.

C#
VB
Copy 

[assembly: ContractNamespaceAttribute("http://www.cohowinery.com/employees",
    ClrNamespace = "Microsoft.Contracts.Examples")]
namespace Microsoft.Contracts.Examples
{
    [DataContract]
    public class Person
    {
        [DataMember]
        internal string FirstName;
        [DataMember]
        internal string LastName;
    }
}
