Protected methodHttpListenerException(SerializationInfo, StreamingContext)Infrastructure. Initializes a new instance of the HttpListenerException class from the specified instances of the SerializationInfo and StreamingContext classes.

Public propertyDataGets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
Public propertyErrorCodeGets a value that identifies the error that occurred. (Overrides ExternalException::ErrorCode.)
Public propertyHelpLinkGets or sets a link to the help file associated with this exception. (Inherited from Exception.)
Protected propertyHResultGets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
Public propertyInnerExceptionGets the Exception instance that caused the current exception. (Inherited from Exception.)
Public propertyMessageGets a message that describes the current exception. (Inherited from Exception.)
Public propertyNativeErrorCodeGets the Win32 error code associated with this exception. (Inherited from Win32Exception.)
Public propertySourceGets or sets the name of the application or the object that causes the error. (Inherited from Exception.)
Public propertyStackTraceGets a string representation of the immediate frames on the call stack. (Inherited from Exception.)
Public propertyTargetSiteGets the method that throws the current exception. (Inherited from Exception.)

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetBaseExceptionWhen overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetObjectDataSets the SerializationInfo object with the file name and line number at which this Win32Exception occurred. (Inherited from Win32Exception.)
Public methodGetTypeGets the runtime type of the current instance. (Inherited from Exception.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that contains the HRESULT of the error. (Inherited from ExternalException.)

Protected eventSerializeObjectStateOccurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.)

This exception is thrown by the HttpListener class and its associated classes when an error occurs during initialization of the HttpListener or while creating or sending a response to an HTTP request. For example, this exception is thrown if the HttpListener attempts to register a Uniform Resource Identifier (URI) prefix that is already registered.
