MySqlConnection打開失敗，訪問被拒絕，即使模仿

我的類庫無法使用MySql .net連接器建立一個mysql連接。如果通過使用類庫的命令行控制檯應用運行它，它可以連接。但是當我使用PHP COM加載/運行.net程序集時，它失敗了。類庫具有模擬代碼來模擬用戶。爲了測試，我模擬了我自己的用戶帳戶。MySqlConnection打開失敗，訪問被拒絕，即使模仿

查看堆棧跟蹤。訪問C：\ Windows \ Microsoft.NET \ Framework \ v2.0.50727 \ Config \ machine.config需要哪些憑據？在.NET程序集中模擬的正確代碼是什麼（它也是COM感知的）？

cacls "C:\Windows\Microsoft.NET\Framework\v2.0.50727\Config\machine.config"在命令提示符將顯示誰/什麼對這個文件的權限。您也想要驗證文件上方所有目錄的訪問權限。
