c# 如何为目录（或文件）设置权限
RT,能有代码更好. --------------------编程问答-------------------- System.IO.File.SetAttributes --------------------编程问答-------------------- MSDN 帮助文档里就有设置文件属性的代码，在 system.io 中。 --------------------编程问答-------------------- System.IO.DirectoryInfo DirInfo = new DirectoryInfo(Path);DirInfo.Attributes = FileAttributes.Normal & FileAttributes.Directory;
参考System.IO.FileAttributes
--------------------编程问答-------------------- public static void changFileAttributes(string strFileName,FileAttributes fa)
{
try
{
if (System.IO.File.Exists(strFileName))
{
File.SetAttributes(strFileName, fa);
}
}
catch
{
}
} --------------------编程问答--------------------
System.IO.DirectoryInfo dirInfo = new System.IO.DirectoryInfo(@"d:\");--------------------编程问答-------------------- System.IO.FileAttributes是一个枚举量 --------------------编程问答-------------------- http://msdn.microsoft.com/en-us/library/system.io.fileattributes.aspx
dirInfo.Attributes = System.IO.FileAttributes.ReadOnly;//只读
用FileAttributes枚举值:
ReadOnly The file is read-only.
Hidden The file is hidden, and thus is not included in an ordinary directory listing.
System The file is a system file. The file is part of the operating system or is used exclusively by the operating system.
Directory The file is a directory.
Archive存档文件 The file's archive status. Applications use this attribute to mark files for backup or removal.
using System;
using System.IO;
using System.Text;
class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
// Create the file if it does not exist.
if (!File.Exists(path))
{
File.Create(path);
}
if ((File.GetAttributes(path) & FileAttributes.Hidden) == FileAttributes.Hidden)
{
// Show the file.
File.SetAttributes(path, FileAttributes.Archive);
Console.WriteLine("The {0} file is no longer hidden.", path);
}
else
{
// Hide the file.
File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden);
Console.WriteLine("The {0} file is now hidden.", path);
}
}
}

--------------------编程问答-------------------- 到帮助中看看System.IO.DirectoryInfo类的详细说明，没有比帮助更详细的说明了
using System;
using System.IO;
using System.Security.AccessControl;
namespace FileSystemExample
{
class FileExample
{
public static void Main()
{
try
{
string fileName = "test.xml";
Console.WriteLine("Adding access control entry for "
+ fileName);
// Add the access control entry to the file.
AddFileSecurity(fileName, @"DomainName\AccountName",
FileSystemRights.ReadData, AccessControlType.Allow);
Console.WriteLine("Removing access control entry from "
+ fileName);
// Remove the access control entry from the file.
RemoveFileSecurity(fileName, @"DomainName\AccountName",
FileSystemRights.ReadData, AccessControlType.Allow);
Console.WriteLine("Done.");
}
catch (Exception e)
{
Console.WriteLine(e);
}
}
// Adds an ACL entry on the specified file for the specified account.
public static void AddFileSecurity(string fileName, string account,
FileSystemRights rights, AccessControlType controlType)
{
// Get a FileSecurity object that represents the
// current security settings.
FileSecurity fSecurity = File.GetAccessControl(fileName);
// Add the FileSystemAccessRule to the security settings.
fSecurity.AddAccessRule(new FileSystemAccessRule(account,
rights, controlType));
// Set the new access settings.
File.SetAccessControl(fileName, fSecurity);
}
// Removes an ACL entry on the specified file for the specified account.
public static void RemoveFileSecurity(string fileName, string account,
FileSystemRights rights, AccessControlType controlType)
{
// Get a FileSecurity object that represents the
// current security settings.
FileSecurity fSecurity = File.GetAccessControl(fileName);
// Add the FileSystemAccessRule to the security settings.
fSecurity.RemoveAccessRule(new FileSystemAccessRule(account,
rights, controlType));
// Set the new access settings.
File.SetAccessControl(fileName, fSecurity);
}
}
}
补充：.NET技术 , C#
