内存泄漏？ [英] Memory Leaks?
问题描述
有没有人注意到他们的VB.NET Windows窗体应用程序中存在内存泄漏？我的应用程序
肯定有一些内存泄漏，所以我做了一个简单的测试，看看它是我的
应用程序还是关于VB.NET的东西。
我创建了一个包含2个表单的测试应用程序。 Form1有一个命令按钮，其代码为
：
Private Sub Button1_Click（ByVal sender As System.Object，ByVal e As
系统。 EventArgs）处理Button1.Click
Dim x As New Form2
x.Show（）
End Sub
观察内存使用情况，我看到当我点击按钮显示Form2时，使用的内存在10-20K之间上涨
。当我关闭Form2时，内存是
没有回收。
关闭表单时我需要做些什么才能回收内存？
谢谢！
Has anyone noticed memory leaks in their VB.NET Windows Forms apps? My app
definitely has some memory leaks, so I did a simple test to see if it was my
app or something about VB.NET.
I created a test app with 2 forms. Form1 has a command button with the
following code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim x As New Form2
x.Show()
End Sub
Watching the memory usage, I see that the used memory goes up between 10-20K
when I click the button to show Form2. When I close Form2, the memory is
not reclaimed.
Is there something I need to do to reclaim memory when closing a form?
Thanks!
推荐答案
Form.Dispose
然后需要一些GC清理前的时间

Form.Dispose
Then it takes some time before GC cleans up
