Application.ApplicationExit Event
.NET Framework (current version)
Note The .NET API Reference documentation has a new home. Visit the
on docs.microsoft.com to see the new experience.Occurs when the application is about to shut down.Namespace:
System.Windows.Forms (in System.Windows.Forms.dll)
public static event EventHandler ApplicationExit
You must attach the event handlers to the
event to perform unhandled, required tasks before the application stops running. You can close files opened by this application, or dispose of objects that garbage collection did not reclaim.Because this is a static event, you must detach any event handlers attached to this event in the ApplicationExit event handler itself. If you do not detach these handlers, they will remain attached to the event and continue to consume memory.The following code example displays two forms and exits the application when both forms are closed. When the application starts and exits, the position of each form is remembered. This example demonstrates using the ApplicationExit event to know when the form positions should be persisted to the file, and when the FileStream should be closed.The class MyApplicationContext inherits from
and keeps track of when each form is closed, and exits the current thread when they both are. The class remembers the position of each form when it is closed. When the ApplicationExit event occurs, the class writes the positions of each for the user to the file. The form position data is stored in a file titled appdata.txt that is created in the location determined by . The Main method calls Application.Run(context) to start the application given the .This code is an excerpt from the example shown in the
class overview. See
for the whole code listing.
private MyApplicationContext() {
formCount = 0;
// Handle the ApplicationExit event to know when the application is exiting.
Application.ApplicationExit += new EventHandler(this.OnApplicationExit);
// Create a file that the application will store user specific data in.
userData = new FileStream(Application.UserAppDataPath + "\\appdata.txt", FileMode.OpenOrCreate);
} catch(IOException e) {
// Inform the user that an error occurred.
MessageBox.Show("An error occurred while attempting to show the application." +
"The error is:" + e.ToString());
// Exit the current thread instead of showing the windows.
ExitThread();
// Create both application forms and handle the Closed event
// to know when both forms are closed.
form1 = new AppForm1();
form1.Closed += new EventHandler(OnFormClosed);
form1.Closing += new CancelEventHandler(OnFormClosing);
formCount++;
form2 = new AppForm2();
form2.Closed += new EventHandler(OnFormClosed);
form2.Closing += new CancelEventHandler(OnFormClosing);
formCount++;
// Get the form positions based upon the user specific data.
if (ReadFormDataFromFile()) {
// If the data was read from the file, set the form
// positions manually.
form1.StartPosition = FormStartPosition.M
form2.StartPosition = FormStartPosition.M
form1.Bounds = form1P
form2.Bounds = form2P
// Show both forms.
form1.Show();
form2.Show();
private void OnApplicationExit(object sender, EventArgs e) {
// When the application is exiting, write the application data to the
// user file and close it.
WriteFormDataToFile();
// Ignore any errors that might occur while closing the file handle.
userData.Close();
} catch {}

exit application是什么意思
我有更好的答案
exit application意思是：退出应用程序以下双语例句：1.&Set capture file, save files or exit application& 设置捕获文件，保存文件或退出应用程序2.In practice, the most obvious repercussion of this difference is that on mac os x, closing the last window ofan application does not exit the application itself. 实际上，这种差别最明显的表现在于，在mac os x中，关闭某应用程序的最后一个窗口并不会让该程序退出。3.Most applications for the installation and run-time temporary files are generated in the normal exit, thegeneral application of the temporary files can be deleted, if the non-normal exit, thetemporary files will be left in the disk. 大多数应用程序在安装和运行时都生成临时文件，在正常退出后，一般的应用程序能删除临时文件，但有的则不能；若是非正常退出，则临时文件会残留在磁盘上。4.Article 20 the owner, or his or her agent, of exit animals and plants, their products or other quarantineobjects shall, before their exit, submit an application for quarantine inspection to the port animal and plantquarantine office. 第二十条货主或者其代理人在动植物、动植物产品和其他检疫物出境前，向口岸动植物检疫机关报检。5.The owners or their agent should fill in application form for approval according to the classifications of entryand exit special goods, one form for one classification. 货主或者其代理人应当根据出入境特殊物品的分类填写《审批申请单》，每一类别填写一份。
