[AttributeUsageAttribute(AttributeTargets.Method, AllowMultiple = true)]
public sealed class SoapHeaderAttribute : Attribute

NameDescription
System_CAPS_pubmethodSoapHeaderAttribute(String)

Initializes a new instance of the SoapHeaderAttribute class, setting the member of the XML Web service class representing the SOAP header contents.

NameDescription
System_CAPS_pubpropertyDirection

Gets or sets whether the SOAP header is intended for the XML Web service or the XML Web service client or both.

System_CAPS_pubpropertyMemberName

Gets or sets the member of the XML Web service class representing the SOAP header contents.

System_CAPS_pubpropertyRequired

Obsolete.This member is obsolete and has no functionality.

System_CAPS_pubpropertyTypeId

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

NameDescription
System_CAPS_pubmethodEquals(Object)

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.)

System_CAPS_pubmethodGetHashCode()

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

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodIsDefaultAttribute()

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

System_CAPS_pubmethodMatch(Object)

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

System_CAPS_pubmethodToString()

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

NameDescription
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.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

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 basic steps to receiving and processing a SOAP header are:

  1. Create a class deriving from SoapHeader representing the data passed in the SOAP header.

  2. Add a member to the XML Web service class or XML Web service client proxy class of the type created in step 1.

  3. Apply a SoapHeaderAttribute to the XML Web service method or the corresponding method in the proxy class, specifying the member created in step 2 in the MemberName property.

  4. Within the XML Web service method or XML Web service client code, access the MemberName property to process the data sent in the SOAP header.

For more details, see the MemberName property.

The following MyWebService XML Web service defines one SoapHeader of type MyHeader. The Hello XML Web service method requires the client to invoke the XML Web service method with this SoapHeader. The Hello XML Web service also catches any SOAP headers other than MyHeader.
