Answer 1

參考一下JAVA數據結構，差不太多

Answer 2

public void InitTree(TreeNodeCollection  Nds,string parentId,DataTable dt)
{  
         dv=new DataView();
TreeNode  tmpNd;
string intId;
dv.Table=dt;
dv.RowFilter="ParentId="  + parentId ;
foreach(DataRowView drv in dv)
{   
                  tmpNd=new TreeNode();
tmpNd.Tag =drv[0].ToString();  //节点ID
tmpNd.Text=drv[2].ToString();  //节点名称
Nds.Add(tmpNd);
intId=drv[1].ToString();       //节点的父节点
InitTree(tmpNd.Nodes,tmpNd.Tag.ToString(),dt);
}
}
