ExternalException 類別

定義

所有 COM Interop 例外狀況 (Exception) 和結構化例外狀況處理 (Structured Exception Handling,SEH) 例外狀況的基底例外狀況類型。The base exception type for all COM interop exceptions and structured exception handling (SEH) exceptions.

public ref class ExternalException : SystemException
[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public class ExternalException : SystemException
type ExternalException = class

備註

為了增強舊版系統與 common language runtime 之間的互通性,ErrorCode 屬性會儲存可識別錯誤的整數值(HRESULT)。To enhance interoperability between legacy systems and the common language runtime, the ErrorCode property stores an integer value (HRESULT) that identifies the error. 使用者定義的例外狀況絕對不應該衍生自 ExternalException,而且使用者程式碼永遠不會擲回 ExternalExceptionUser defined exceptions should never derive from ExternalException, and an ExternalException should never be thrown by user code. 請改用衍生自 ExternalException 的特定例外狀況。Use the specific exceptions that derive from ExternalException instead.

ExternalException 使用具有值0x80004005 的 HRESULT E_FAIL。ExternalException uses the HRESULT E_FAIL which has the value 0x80004005.

ExternalException 使用預設的 Equals 實值,其支援參考相等。ExternalException uses the default Equals implementation, which supports reference equality.

如需 ExternalException實例的初始值清單,請參閱 ExternalException 的函式。For a list of initial values for an instance of ExternalException, see the ExternalException constructors.

建構函式

ExternalException()

使用預設屬性,初始化 ExternalException 類別的新執行個體。Initializes a new instance of the ExternalException class with default properties.

ExternalException(SerializationInfo, StreamingContext)

從序列化 (Serialization) 資料,初始化 ExternalException 類別的新執行個體。Initializes a new instance of the ExternalException class from serialization data.

ExternalException(String)

使用指定的錯誤訊息,初始化 ExternalException 類別的新執行個體。Initializes a new instance of the ExternalException class with a specified error message.

ExternalException(String, Exception)

使用指定的錯誤訊息以及造成此例外狀況的內部例外狀況的參考,初始化 ExternalException 類別的新執行個體。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)

使用指定的錯誤訊息和錯誤的 HRESULT,初始化 ExternalException 類別的新執行個體。Initializes a new instance of the ExternalException class with a specified error message and the HRESULT of the error.
