如何从vb.net中的Temp文件夹中删除文件 [英] How to delete file from Temp Folder in vb.net

问题描述

Hai

为什么我要问这个问题，我想删除特定文件夹（Temp）中的所有文件，因为所有文件都是pdf文件，该文件是从sql server下载的表格并保存在临时文件夹并在pdf查看器中打开。在看到pdf文件后，我关闭了应用程序（vb.net中的Windows应用程序），我想在关闭应用程序之前删除TEMP文件夹中的所有文件。如果pdf文件在pdf查看器中打开，我就无法删除文件格式Temp文件夹，它显示错误，如文件无法删除，因为它被其他应用程序使用这样的东西....

如果文件未在查看器中打开我可以删除临时文件夹，但如果文件在查看器中打开我无法删除文件夹

请回复asap

我通过首先从pdf查看器中删除文件解决了这个问题，如果文件未在查看器中打开没有问题，否则文件在查看器中打开我们必须清除该文件并使用删除方法清除文件夹。
