Question

System.Security.AccessControl.DirectorySecurity是什么意思

System.IO.DirectoryInfo dInfo = new System.IO.DirectoryInfo(FileWay);
System.Security.AccessControl.DirectorySecurity dSecurity = dInfo.GetAccessControl();
dSecurity.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule("Everyone",
System.Security.AccessControl.FileSystemRights.Write,
InheritanceFlags.ObjectInherit, PropagationFlags.NoPropagateInherit, System.Security.AccessControl.AccessControlType.Allow));
dInfo.SetAccessControl(dSecurity);
我知道作用，只是不清楚为什么这样写，高手讲解一下

Answer 1

//得到目录的当前信息
System.IO.DirectoryInfo dInfo = new System.IO.DirectoryInfo(FileWay);
//从目录信息里提取其中的安全访问信息
System.Security.AccessControl.DirectorySecurity dSecurity = dInfo.GetAccessControl();
//实例化一个访问规则，并添加到目录信息
dSecurity.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule("Everyone",
System.Security.AccessControl.FileSystemRights.Write,
InheritanceFlags.ObjectInherit, PropagationFlags.NoPropagateInherit, System.Security.AccessControl.AccessControlType.Allow));
//将修改后的目录信息重新附给目录
dInfo.SetAccessControl(dSecurity);
