範例

以下範例建立一個新的 實 ErrorEventArgs 例，並以 Exception初始化 。 接著範例呼叫 GetException 取回 並 Exception 顯示錯誤訊息。 此代碼沒有固定形式。


public static void Main(string[] args) {
   //Creates an exception with an error message.
   Exception myException= new Exception("This is an exception test");

   //Creates an ErrorEventArgs with the exception.
   ErrorEventArgs myErrorEventArgs = new ErrorEventArgs(myException);

   //Extracts the exception from the ErrorEventArgs and display it.
   Exception myReturnedException = myErrorEventArgs.GetException();
   MessageBox.Show("The returned exception is: " + myReturnedException.Message);
}

Public Shared Sub Main()
    'Creates an exception with an error message.
    Dim myException As New Exception("This is an exception test")
       
    'Creates an ErrorEventArgs with the exception.
    Dim myErrorEventArgs As New ErrorEventArgs(myException)
       
    'Extracts the exception from the ErrorEventArgs and display it.
    Dim myReturnedException As Exception = myErrorEventArgs.GetException()
    MessageBox.Show("The returned exception is: " _
       + myReturnedException.Message)
End Sub
