NameDescription
System_CAPS_pubmethodAbandonedMutexException()

Initializes a new instance of the AbandonedMutexException class with default values.

System_CAPS_pubmethodAbandonedMutexException(Int32, WaitHandle)

Initializes a new instance of the AbandonedMutexException class with a specified index for the abandoned mutex, if applicable, and a Mutex object that represents the mutex.

System_CAPS_protmethodAbandonedMutexException(SerializationInfo, StreamingContext)

Initializes a new instance of the AbandonedMutexException class with serialized data.

System_CAPS_pubmethodAbandonedMutexException(String)

Initializes a new instance of the AbandonedMutexException class with a specified error message.

System_CAPS_pubmethodAbandonedMutexException(String, Exception)

Initializes a new instance of the AbandonedMutexException class with a specified error message and inner exception.

System_CAPS_pubmethodAbandonedMutexException(String, Exception, Int32, WaitHandle)

Initializes a new instance of the AbandonedMutexException class with a specified error message, the inner exception, the index for the abandoned mutex, if applicable, and a Mutex object that represents the mutex.

System_CAPS_pubmethodAbandonedMutexException(String, Int32, WaitHandle)

Initializes a new instance of the AbandonedMutexException class with a specified error message, the index of the abandoned mutex, if applicable, and the abandoned mutex.

NameDescription
System_CAPS_pubpropertyData

Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)

System_CAPS_pubpropertyHelpLink

Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)

System_CAPS_pubpropertyHResult

Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)

System_CAPS_pubpropertyInnerException

Gets the Exception instance that caused the current exception.(Inherited from Exception.)

System_CAPS_pubpropertyMessage

Gets a message that describes the current exception.(Inherited from Exception.)

System_CAPS_pubpropertyMutex

Gets the abandoned mutex that caused the exception, if known.

System_CAPS_pubpropertyMutexIndex

Gets the index of the abandoned mutex that caused the exception, if known.

System_CAPS_pubpropertySource

Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)

System_CAPS_pubpropertyStackTrace

Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)

System_CAPS_pubpropertyTargetSite

Gets the method that throws the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_pubmethodEquals(Object)

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

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetBaseException()

When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)

System_CAPS_pubmethodGetHashCode()

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

System_CAPS_pubmethodGetObjectData(SerializationInfo, StreamingContext)

When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)

System_CAPS_pubmethodGetType()

Gets the runtime type of the current instance.(Inherited from Exception.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current exception.(Inherited from Exception.)

NameDescription
System_CAPS_proteventSerializeObjectState

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

When a thread abandons a mutex, the exception is thrown in the next thread that acquires the mutex. The thread might acquire the mutex because it was already waiting on the mutex or because it enters the mutex at a later time.

An abandoned mutex indicates a serious programming error. When a thread exits without releasing the mutex, the data structures protected by the mutex might not be in a consistent state. Prior to version 2.0 of the .NET Framework, such problems were hard to discover because no exception was thrown if a wait completed as the result of an abandoned mutex. For more information, see the Mutex class.

The next thread to request ownership of the mutex can handle this exception and proceed, provided that the integrity of the data structures can be verified.

The following code example executes a thread that abandons five mutexes, demonstrating their effects on the WaitOne, WaitAny, and WaitAll methods. The value of the MutexIndex property is displayed for the WaitAny call.

System_CAPS_noteNote

The call to the WaitAny method is interrupted by one of the abandoned mutexes. The other abandoned mutex could still cause an AbandonedMutexException to be thrown by subsequent wait methods.
