代碼訪問安全性問題 - 這裏有什麼問題？

Question

背景

我有我用它來生成包含我們的應用程序的當前版本號一些批處理文件生成後事件。該事件調用批處理文件，該文件調用managed app加載程序集並使用反射來查找其版本信息。

問題

當生成後事件在本地運行，每天的罰款。當它在我們的自動構建過程中運行時，我在日誌中看到以下錯誤。我對Code Access Security一無所知，並希望有人能夠快速指出問題。

Answer 1

您使用的是哪個版本的框架？舊版本不太信任網絡共享 - 因此您可能需要使用「caspol」來啓用信任（或在運行之前在本地移動文件）。最近，框架確實信任映射股（如Q:\），但不信任UNC股份（\\someserver\whatever）沒有「caspol」調整。

儘管最簡單的選擇是從本地驅動器而不是通過網絡運行exe。
