解决方案

有办法强迫这个，但这是一个坏主意 - 你可能会导致更多通过强制用户知道并手动关闭应用程序来强制手柄过早关闭造成的损坏。



但是......你说它说它开放在我的程序中这意味着你已经打开了文件 - 这是有意义的，因为你正在扫描它 - 并且尚未关闭并使用交换机处理你正在阅读文件的流。在这种情况下，我在第一段中所做的评论生效 - 您将关闭您自己的应用程序正在使用的内容，并且您的应用程序很可能会因强制删除而崩溃。 />
相反，请检查您的代码，并确保在尝试删除它们之前，所有流，文件句柄或用于访问文件的任何内容都已正确处理。

  Dim  isSuspect  As  布尔 = 错误 
 使用 fs  As  新 FileStream（path，FileAccess.Read）
 isSuspect = ScanMyFile（fs）
 结束 使用 
 如果 isSuspect 然后 
 ' 您可以在此删除文件 
 ... 
 
 结束 如果

解决方案

There are ways to force this, but it's a bad idea - you will probably cause more damage by forcing the handle to close prematurely than you will save by lettign the user know and close the application manually.

But ... you say "its saying its open in my program" which implies you have opened the file - which makes sense since you are scanning it - and have not yet closed and disposed your stream with switch you are reading the file. In which case, the comment I made in the first paragraph comes into effect - you will be closing somthing your own application is using, and there is a very good chance that your app will crash as a result of your forcing the delete.
Instead, check your code, and make sure that all streams, file handles or whatever you are using to access files are correctly Disposed before you try to delete them.

Dim isSuspect As Boolean = False
Using fs As New FileStream(path, FileAccess.Read)
	isSuspect = ScanMyFile(fs)
End Using
If isSuspect Then
	' You can delete the file here
	...

End If
