推荐答案

该进程无法对文件夹 C：\ Windows \\\ TEMP 进行写入访问，这是因为是一个系统文件夹，需要管理权限才能读取和写入。



它在您的本地项目中运行表明您以管理员身份运行它（o r - 更糟糕的是 - 已经改变了文件夹的访问权限。）



您应该检查代码中哪个文件夹被定义为临时文件夹，而不是使用其中一个运行应用程序的用户的临时文件夹。

The process has no write access to the folder C:\Windows\TEMP which is expected because that is a system folder requiring administrative privileges for reading and writing.

That it works in your local project indicates that you are running it there as Administrator (or - even worse - has changed the access rights of the folder).

You should check where in your code that folder is defined as temporary folder instead of using one of the temporary folders of the user running the application.
