C#讀取Win32標準DLL檔案中的字串資源

在C#中，通過Windows API函數讀取標準的Win32 DLL檔案中的字串資源

下面的代碼以讀取 user32.DLL 檔案中的ＩＤ號為712的字串資源。

如果代碼運行正常的話，應該可以看到

/*

Other people are logged on to this remote computer.  Shutting down Windows might cause them to lose data. Also, someone at the remote location will have to restart the computer manually./r/n/r/nDo you want to continue shutting down?

如果是中文版的ＸＰ，此處的字串則不同
