| Name | Description | |
|---|---|---|
![]() | CryptographicUnexpectedOperationException() | Initializes a new instance of the CryptographicUnexpectedOperationException class with default properties. |
![]() | CryptographicUnexpectedOperationException(SerializationInfo, StreamingContext) | Initializes a new instance of the CryptographicUnexpectedOperationException class with serialized data. |
![]() | CryptographicUnexpectedOperationException(String) | Initializes a new instance of the CryptographicUnexpectedOperationException class with a specified error message. |
![]() | CryptographicUnexpectedOperationException(String, Exception) | Initializes a new instance of the CryptographicUnexpectedOperationException class with a specified error message and a reference to the inner exception that is the cause of this exception. |
![]() | CryptographicUnexpectedOperationException(String, String) | Initializes a new instance of the CryptographicUnexpectedOperationException class with a specified error message in the specified format. |
| 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 | |
![]() | 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.) |
| 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 it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetBaseException() | |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetObjectData(SerializationInfo, StreamingContext) | 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() | |
![]() | ToString() | Creates and returns a string representation of the current exception.(Inherited from Exception.) |
| Name | Description | |
|---|---|---|
![]() | SerializeObjectState | Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.) |
CryptographicUnexpectedOperationException uses the HRESULT CORSEC_E_CRYPTO_UNEX_OPER, which has the value 0x80131431.
