{
bool result;
//获取⽬录信息
var folder = new DirectoryInfo(folderPath);
//获取当前⽂件夹ACL
var dSecurity = folder.GetAccessControl(AccessControlSections.All);
//设置新的ACL规则
var accRule = new FileSystemAccessRule(userName, rights, inherits, propagateToChildren, allowOrDeny);
//修改⽂件夹ACL
dSecurity.ModifyAccessRule(addResetOrRemove, accRule, out result);
//应⽤新的ACL规则到⽂件夹
folder.SetAccessControl(dSecurity);
//返回结果
return result;
}
下⾯这样调⽤
var folderPath = System.AppDomain.CurrentDomain.BaseDirectory;
var userName = "Users";
SetFolderACL(folderPath, userName, FileSystemRights.FullControl, AccessControlType.Allow);
