The ExternalException type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | ExternalException() | Initializes a new instance of the ExternalException class with default properties. |
![]() ![]() | ExternalException(String) | Initializes a new instance of the ExternalException class with a specified error message. |
![]() | ExternalException(SerializationInfo, StreamingContext) | Initializes a new instance of the ExternalException class from serialization data. |
![]() ![]() | ExternalException(String, Exception) | Initializes a new instance of the ExternalException class with a specified error message and a reference to the inner exception that is the cause of this exception. |
![]() | ExternalException(String, Int32) | Initializes a new instance of the ExternalException class with a specified error message and the HRESULT of the error. |
| Name | Description | |
|---|---|---|
![]() | Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
![]() ![]() | ErrorCode | Gets the HRESULT of the error. |
![]() | 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.) |
| 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 | 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.) |
![]() | 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.) In XNA Framework 3.0, this member is inherited from Object.GetType(). |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that contains the HRESULT of the error. (Overrides Exception.ToString().) In XNA Framework, this member is overridden by ToString(). |
| 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.) |
To enhance interoperability between legacy systems and the common language runtime, the ErrorCode property stores an integer value (HRESULT) that identifies the error. User defined exceptions should never derive from ExternalException, and an ExternalException should never be thrown by user code. Use the specific exceptions that derive from ExternalException instead.
ExternalException uses the HRESULT E_FAIL which has the value 0x80004005.
ExternalException uses the default Equals implementation, which supports reference equality.
