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);
