FaultException(Of TDetail) Class
Used in a client application to catch contractually specified SOAP faults.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|Action||Gets the value of the SOAP action for the fault message. (Inherited from FaultException.)|
|Code||Gets the fault code for the SOAP fault. (Inherited from FaultException.)|
|Data||Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)|
|Detail||Gets the object that contains the detail information of the fault condition.|
|HResult||Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)|
|InnerException||Gets the Exception instance that caused the current exception. (Inherited from Exception.)|
|Message||Gets the message for the exception. (Inherited from FaultException.)|
|Reason||Gets the FaultReason for the SOAP fault. (Inherited from FaultException.)|
|StackTrace||Gets a string representation of the frames on the call stack at the time the current exception was thrown. (Inherited from Exception.)|
|CreateMessageFault||Returns an in-memory MessageFault object. (Inherited from FaultException.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetBaseException||When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the runtime type of the current instance. (Inherited from Exception.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string for the object. (Overrides Exception.ToString.)|
Catch the object in a Silverlight client application to handle a SOAP fault that has been contractually specified in an operation contract.
Typical deployed services use the FaultContractAttribute to formally specify all SOAP faults that a client can expect to receive in the normal course of an operation. Error information in a FaultContractAttribute appears as a (where the type parameter is the serializable error object specified in the operation's FaultContractAttribute) when it arrives at a client application. The FaultContractAttribute can be used to specify SOAP faults for both two-way service methods and for asynchronous method pairs.
Because is both a FaultException and therefore a CommunicationException, to catch specified SOAP faults make sure you catch the types prior to the FaultException and CommunicationException types or handle the specified exceptions in one of those exception handlers.
If you use System.ServiceModel.FaultContractAttribute to specify a where the type parameter is a System.String, the string value is assigned to the Detail property in the client application; clients cannot retrieve that string by calling the FaultException(Of TDetail).ToString method. To have the string value returned when the client application calls Exception.ToString, throw a System.ServiceModel.FaultException exception inside the operation and pass the string to the constructor. In general, it is recommended that detail types be custom serializable types appropriate to the fault and not a System.String.
The following code example shows how a service uses the type to throw a managed exception that gets converted into the SOAP fault specified by the FaultContractAttribute.
The following code example shows how the client code looks when imported by the client using the SLsvcutil.exe.
The following code example shows how a client can catch the type that represents the custom SOAP fault specified in the operation contract.
