推荐答案

有 Form_Closing 事件.用来删除您的txt文件.

There is Form_Closing event. Used that to delete your txt file.

要删除该文件，请使用File.Delete(string filepath)方法.

To delete the file, use File.Delete(string filepath) method.

您可以使用已关闭事件:

如果您有 FileStream ，并且您希望在表单已关闭，您可以使用设计器或在表单的构造函数中，将事件处理程序添加到Closed事件中，如下所示:

If you have a FileStream and you want to close it when the form is closed, you can add an event-handler to the Closed event using the designer or, in the constructor of your form, like the following:

this.Closed += new EventHandler(Form1_Closed);

并实现事件处理程序以关闭文件，如下所示:

and implement the event-handler to close your file, like the following:

void Form1_Closed(object sender, EventArgs e)
{
    myFileStream.Close();
}
