Soap12FaultCodes Class


Defines the SOAP fault codes that appear in a SOAP message when an error occurs while communicating with XML Web services using the SOAP version 1.2 protocol.

Namespace:   System.Web.Services.Protocols
Assembly:  System.Web.Services (in System.Web.Services.dll)


public sealed class Soap12FaultCodes


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


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


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


Represents the SOAP version 1.2 DataEncodingUnknown fault code indicating the SOAP message is encoded in an unrecognized format.



Represents the SOAP version 1.2 enc:UntypedValue fault subcode indicating that the SOAP message was RPC-encoded and the type name property of an encoded graph node was not specified.


Represents the SOAP version 1.2 MustUnderstand fault code indicating a SOAP header marked with the MustUnderstand attribute was not processed.


Represents the SOAP version 1.2 Receiver fault code indicating an error occurred during the processing of a client call on the server due to a problem with the recipient.


Represents the SOAP version 1.2 rpc:BadArguments fault subcode indicating that arguments sent to the XML Web service method were incorrect or could not be parsed.


Represents the SOAP version 1.2 rpc:ProcedureNotPresent fault subcode indicating the XML Web service does not support the requested XML Web service method.


Represents the SOAP version 1.2 Sender fault code indicating a client call was not formatted correctly or did not contain the appropriate information.


Represents the SOAP version 1.2 VersionMismatch fault code indicating the XML Web service expected SOAP messages conforming to the SOAP 1.2 specification, yet received one conforming to SOAP 1.1.

A SOAP fault in version 1.2 of the SOAP specification contains a Code element and among other things an optional Subcode element. The Code element is one of a pre-defined set of codes, informing a recipient that the cause of the error fell into one of five large error categories. Those five fault codes are represented by the ReceiverFaultCode, SenderFaultCode, VersionMismatchFaultCode, MustUnderstandFaultCode, and DataEncodingUnknownFaultCode fields. The Subcode element allows the sender of the SOAP fault to provide an application-specific error code. ASP.NET defines two such codes that are represented by the RpcProcedureNotPresentFaultCode, RpcBadArgumentsFaultCode, F:System.Web.Services.Protocols.Soap12FaultCodes.EncodingMissingIDFaultCode, and EncodingUntypedValueFaultCode fields.

An XML Web service throwing an exception sets the Code property, which represents the Code element, when a new instance of the SoapException or SoapHeaderException class is created. That error is transmitted over the wire as a SOAP fault, which a .NET Framework client can catch as a SoapException or SoapHeaderException.
