Represents a communication error in either the service or client application.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|CommunicationException()||Initializes a new instance of the class.|
|CommunicationException(String)||Initializes a new instance of the class, using the specified message.|
|CommunicationException(SerializationInfo, StreamingContext)||Initializes a new instance of the class, using the specified serialization information and context objects.|
|CommunicationException(String, Exception)||Initializes a new instance of the class, using the specified message and the inner exception.|
|Data||Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)|
|HelpLink||Gets or sets a link to the help file associated with this exception. (Inherited from Exception.)|
|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 a message that describes the current exception. (Inherited from Exception.)|
|Source||Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.)|
|StackTrace||Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.)|
|TargetSite||Gets the method that throws the current exception. (Inherited from Exception.)|
|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 it 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 the default hash function. (Inherited from Object.)|
|GetObjectData||When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception.)|
|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||Creates and returns a string representation of the current exception. (Inherited from Exception.)|
Robust client and service Windows Communication Foundation (WCF) applications handle objects that may be thrown during communication. There are also two -derived exception types (FaultException<TDetail> and FaultException) that clients also often expect. Therefore, in order to prevent the generic handler from catching these more specific exception types, catch these exceptions prior to handling .
FaultException<TDetail> objects are thrown on the client when a SOAP fault that is specified in the operation contract is received in response to a two-way operation (that is, a method with an OperationContractAttribute attribute with IsOneWay set to false).
FaultException objects are thrown when a listener receives a SOAP fault that is not expected or specified in the operation contract. This usually occurs when the application is being debugged and the service has the IncludeExceptionDetailInFaults property set to true.
When implementing custom channels and binding elements, it is strongly recommended that your components throw only System::TimeoutException or -derived objects. In the case where your components throw a recoverable exception that is specific to the component, wrap that exception inside a object.
For more details about designing and using the WCF fault system, see Specifying and Handling Faults in Contracts and Services.
The WCF Runtime will not throw a that is unsafe to handle at the point where it leaves the WCF Runtime and enters user code.
