Gets or sets the name of the binding.


Gets or sets the namespace associated with the binding.


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


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.)

A binding, as defined by Web Services Description Language (WSDL), is similar to an interface, in that it defines a concrete set of operations. Each XML Web service method is an operation within a particular binding. XML Web service methods are members of either the default binding for an XML Web service or a binding specified within a WebServiceBindingAttribute applied to a class implementing an XML Web service. An XML Web service can implement multiple bindings, by applying multiple WebServiceBindingAttribute attributes to an XML Web service.

Once one or more WebServiceAttribute attributes are applied to an XML Web service, a SoapDocumentMethodAttribute or SoapRpcMethodAttribute can be applied to individual XML Web service methods to indicate the binding operation implemented by a particular XML Web service method. Set the Binding property of SoapDocumentMethodAttribute or SoapRpcMethodAttribute to specify the binding an XML Web service method is implementing an operation for.

The following XML Web service implements operations from four bindings. Specifically, the XML Web service declares three bindings it implements operations for, by applying three WebServiceBindingAttribute attributes to the XML Web service.

To specify which binding an XML Web service method is implementing an operation for, a SoapDocumentMethodAttribute is applied to each of the XML Web service methods, except DefaultBindingMethod. By not specifying a binding for DefaultBindingMethod, it is implementing an operation on the default binding for the XML Web service.
