權限管理，ps：抄的領導的，比較粗糙，一切挺好的，就是沒有那個編輯用戶權限時，默認選中原來已有的權限節點。

效果如下：

Action里調用的Bll里的方法，有一點兒需要注意的就是：使用的遞歸方法，循環插入節點，返回節點列表

方法：

private void GetTree(int parentID, BasicMainTreeView moParent)
{
List<BasicMainTreeView> modelInfo = models.Where(Model => Model.parentID == parentID).ToList();
foreach (BasicMainTreeView model in modelInfo)
{
BasicMainTreeView mo = new BasicMainTreeView();
mo = model;
moParent.children.Add(mo);
GetTree(mo.id, mo);
}
}里的?models.Where(Model => Model.parentID == parentID).ToList();剛開始挺讓我費解的[ps：我太笨了，，] 有大仙兒網友說：就類似于：select * from?model where?model.parentID=parentID ? 查詢條件是parentID

?

千萬別忘了。。。
