解决asp.net访问某个文件夹没有权限（转）

private void SetRight(string folderpath)
{
bool result = false;
DirectoryInfo folder = new DirectoryInfo(folderpath);
folder.Attributes |= FileAttributes.Normal;
folder.Attributes &= ~FileAttributes.Hidden; // remove the folder Hidden attribute
folder.Attributes &= ~FileAttributes.ReadOnly;// remove the folder ReadOnly attribute
DirectorySecurity foldersecurity = new DirectorySecurity();
FileSystemAccessRule filerule = new FileSystemAccessRule("INTERACTIVE", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly, AccessControlType.Allow);
FileSystemAccessRule filerule1 = new FileSystemAccessRule("NETWORK SERVICE", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly, AccessControlType.Allow);
FileSystemAccessRule filerule2 = new FileSystemAccessRule("NETWORK", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly, AccessControlType.Allow);
foldersecurity.ModifyAccessRule(AccessControlModification.Add, filerule, out result);
foldersecurity.ModifyAccessRule(AccessControlModification.Add, filerule1, out result);
foldersecurity.ModifyAccessRule(AccessControlModification.Add, filerule2, out result);
folder.SetAccessControl(foldersecurity);
}

注：folderpath为文件夹路径，将需要获得权限的文件夹路径传入方法即可。
