範例

這個程式碼範例是針對 FileStream.Lock 方法所提供之較大範例的一部分。This code example is part of a larger example provided for the FileStream.Lock method.

// Catch the IOException generated if the 
// specified part of the file is locked.
catch ( IOException^ e ) 
{
   Console::WriteLine( "{0}: The write operation could not "
   "be performed because the specified "
   "part of the file is locked.", e->GetType()->Name );
}


// Catch the IOException generated if the
// specified part of the file is locked.
catch(IOException e)
{
    Console.WriteLine(
        "{0}: The write operation could not " +
        "be performed because the specified " +
        "part of the file is locked.",
        e.GetType().Name);
}
' Catch the IOException generated if the 
' specified part of the file is locked.
Catch ex As IOException
    Console.WriteLine( _
        "{0}: The write operation could " & _
        "not be performed because the " & _
        "specified part of the file is " & _
        "locked.", ex.GetType().Name)
End Try

備註

使用資料流、檔案和目錄存取資訊時,IOException 是擲回之例外狀況的基底類別。IOException is the base class for exceptions thrown while accessing information using streams, files and directories.

基類庫包含下列型別,每個型別都是 IOException 的衍生類別:The Base Class Library includes the following types, each of which is a derived class of IOException :

適當時,請使用這些類型,而不是 IOException。Where appropriate, use these types instead of IOException.

IOException 使用具有值0x80131620 的 HRESULT COR_E_IO。IOException uses the HRESULT COR_E_IO which has the value 0x80131620.

建構函式

IOException()

初始化 IOException 類別的新執行個體,並將其訊息字串設定為空字串 ("")、其 HRESULT 設定為 COR_E_IO 及其內部例外狀況設定為 Null 參考。Initializes a new instance of the IOException class with its message string set to the empty string (""), its HRESULT set to COR_E_IO, and its inner exception set to a null reference.

IOException(SerializationInfo, StreamingContext)

使用指定的序列化及內容資訊,初始化 IOException 類別的新執行個體。Initializes a new instance of the IOException class with the specified serialization and context information.

IOException(String)

初始化 IOException 類別的新執行個體,並將其訊息字串設定為 message、將其 HRESULT 設定為 COR_E_IO 及將其內部例外狀況設定為 nullInitializes a new instance of the IOException class with its message string set to message, its HRESULT set to COR_E_IO, and its inner exception set to null.

IOException(String, Exception)

使用指定的錯誤訊息以及造成此例外狀況之內部例外狀況的參考,初始化 IOException 類別的新執行個體。Initializes a new instance of the IOException class with a specified error message and a reference to the inner exception that is the cause of this exception.

IOException(String, Int32)

將其訊息字串設定為 message 並將其 HRESULT 設定為使用者定義,初始化 IOException 類別的新執行個體。Initializes a new instance of the IOException class with its message string set to message and its HRESULT user-defined.

(繼承來源 Exception)

事件

SerializeObjectState

當例外狀況序列化,以建立包含例外狀況相關序列化資料的例外狀況狀態物件時,就會發生此事件。Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.
