| ProtocolException(String) | Initializes a new instance of the ProtocolException class with a specified error message. |
| ProtocolException(String, Exception) | Initializes a new instance of the ProtocolException class with a specified error message and a reference to the inner exception that is the cause of the exception. |
| Name | Description | |
|---|---|---|
 | 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 frames on the call stack at the time the current exception was thrown. (Inherited from Exception.) |
| Name | Description | |
|---|---|---|
| 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.) |

The ProtocolException can be caused by incompatible bindings between endpoints, the use of an incorrect remote endpoint address, or similar incorrect configuration.
This exception derives from CommunicationException that represents a class of recoverable errors that may be thrown during communication between endpoints and that robust client and service Windows Communication Foundation (WCF) applications are expected to handle. To prevent a handler for CommunicationException from catching the more specific ProtocolException, catch this exception prior to handling CommunicationException.
