其实在.NET中一切的操作和编程变的非常的简单而明了。如想要添加一个文件或文件夹访问用户并为其设置权限的话，如果在C++中实现则非常的复杂。并同时要调用那些烦人的API函数才能完成。但在.NET中则不同，因为.NET中用了很多已封装的类来完成。其实封装类的内部已经封装了系统的API函数从而解决了应用层的编程者。
以下是C#实现。用Visual Studio 2010编写，在WIN 7中测试通过。
1、文件
static void Main(string[] args)
{
SetAccount(@"C:\eee.txt", "BATCH");
Console.WriteLine("OK");
Console.Read();
}
public static void SetAccount(string filePath, string username)
{
FileInfo fileInfo = new FileInfo(filePath);
FileSecurity fileSecurity = fileInfo.GetAccessControl();
dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl, AccessControlType.Allow)); //以完全控制为例
dirinfo.SetAccessControl(fileSecurity );
}
2、文件夹
public static void Main()
{
SetFolderACL("C:\\test", "BATCH", FileSystemRights.FullControl, AccessControlType.Allow);
}
public static bool SetFolderACL(String FolderPath, String UserName, FileSystemRights Rights, AccessControlType AllowOrDeny)
{
InheritanceFlags inherits = InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit;
return SetFolderACL(FolderPath, UserName, Rights, AllowOrDeny, inherits, PropagationFlags.None, AccessControlModification.Add);
}
public static bool SetFolderACL(String FolderPath, String UserName, FileSystemRights Rights, AccessControlType AllowOrDeny, InheritanceFlags Inherits, PropagationFlags PropagateToChildren, AccessControlModification AddResetOrRemove)
{
bool ret;
DirectoryInfo folder = new DirectoryInfo(FolderPath);
DirectorySecurity dSecurity = folder.GetAccessControl(AccessControlSections.All);
FileSystemAccessRule accRule = new FileSystemAccessRule(UserName, Rights, Inherits, PropagateToChildren, AllowOrDeny); dSecurity.ModifyAccessRule(AddResetOrRemove, accRule, out ret);
folder.SetAccessControl(dSecurity);
return ret;
}
