本文提供了两种在Windows环境下通过编程方式设置文件夹权限的方法。一种是使用1.0版本的方法，涉及调用Windows API并利用Microsoft.Win32.Security命名空间；另一种是2.0版本的方法，使用了System.IO和System.Security.AccessControl命名空间来更简洁地为文件夹添加everyone权限。

给文件权限everyone

代码

以下是1.0的方法，调用Windows   API
  using   Microsoft.Win32.Security;

  private   Boolean   CreateDir(String   strSitePath,   String   strUserName)

  {
       Boolean   bOk;
      try

      {
        Directory.CreateDirectory(strSitePath);
      SecurityDescriptor   secDesc   =   SecurityDescriptor.GetFileSecurity(strSitePath,SECURITY_INFORMATION.DACL_SECURITY_INFORMATION);
           Dacl   dacl   =   secDesc.Dacl;
           Sid   sidUser   =   new   Sid   (strUserName);


         //   allow:   folder,   subfolder   and   files
         //   modify
        dacl.AddAce(new   AceAccessAllowed(sidUser,   AccessType.GENERIC_WRITE   |   AccessType.GENERIC_READ   |   AccessType.DELETE   |   AccessType.GENERIC_EXECUTE   ,   AceFlags.OBJECT_INHERIT_ACE   |   AceFlags.CONTAINER_INHERIT_ACE));


                              //   deny:   this   folder
                              //   write   attribs
                              //   write   extended   attribs
                              //   delete
                              //   change   permissions
                              //   take   ownership
     DirectoryAccessType   DAType   =   DirectoryAccessType.FILE_WRITE_ATTRIBUTES   |   DirectoryAccessType.FILE_WRITE_EA   |   DirectoryAccessType.DELETE   |   DirectoryAccessType.WRITE_OWNER   |   DirectoryAccessType.WRITE_DAC;
            AccessType   AType   =   (AccessType)DAType;
            dacl.AddAce   (new   AceAccessDenied   (sidUser,   AType));

      secDesc.SetDacl(dacl);
     secDesc.SetFileSecurity(strSitePath,   SECURITY_INFORMATION.DACL_SECURITY_INFORMATION);
      bOk   =   true;
     }

catch

     {
       bOk   =   false;
     }
     return   bOk;

  }

  2.0的,里面的方法是2.0中新加的：
  System.IO.DirectoryInfo   dInfo   =   new   System.IO.DirectoryInfo("Your   Forlder   Path   here");
        System.Security.AccessControl.DirectorySecurity   dSecurity   =   new   System.Security.AccessControl.DirectorySecurity();
        dSecurity.AddAccessRule(new   System.Security.AccessControl.FileSystemAccessRule("Everyone",   System.Security.AccessControl.FileSystemRights.WriteData,   System.Security.AccessControl.AccessControlType.Allow));
         dInfo.SetAccessControl(dSecurity);

在网上找了半天也只找到这个代码，而且只能用加everyone权限。有哪位知道告诉我一声，先谢了！
