我有一个使用Process.Start()
. 我调用的可执行文件是一个第三方程序,用于更新ProgramData
. 一旦我的程序中的文件夹ProgramData
得到更新,我的程序中的下一组行会尝试读取最新的更改。
我注意到即使在执行可执行文件后也无法读取最新的更改,但是当我从头开始再次运行我的程序时,我可以看到更改被正确读取。我假设这与AppDomain
在执行期间无法看到更改有关。
无论如何我可以在这里工作吗?
在下面的方法内部代码中,HSMTransactionHandler
如果发生带有消息的异常HSM_ENCRYPTION_KEY_NOT_FOUND
,则我通过调用方法执行exe UpdateFromRFS
,然后HSMTransactionHandler
递归调用。exe 的执行获得了所需的资源,但代码没有读取它。如果我在当前程序执行期间运行另一个程序,第二个程序读取资源没有任何问题。ProgramData
这让我想到一个进程或应用程序域是否可以看到文件夹启动后发生的更改?
只是为了让每个人都知道我正在使用库,它是围绕本机 dll 构建PKCS11Interop
的托管包装器。.net
我也不确定使用本机 dll 是否会导致这种情况。
任何帮助将不胜感激。

编辑 2:我检查并发现它甚至没有设置CKNFAST_ASSUME_SINGLE_PROCESS
为 0 就可以工作,所以可能只需要处理 pkcs11 对象并重新初始化它
