asp.net 设置文件权限

给文件权限everyone 以下是1.0的方法，调用Windows API using Microsoft.Win32.Security; http://www.gotdotnet.com/Community/UserSamples/Details.aspx?SampleGuid=e6098575-dda0-48b8-9abf-e0705af065d9 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);
