怎样改为从数据库读入数据来实现树型表示啊？（假设ACCESS 数据库。文件名db1.mdb）求救。。。急！

用循环去动态生成结点。

典型的浮躁，编程序首先要分析，这个都不想做不如不要做程序员这行了，鄙视

很简单的，你自己想搞清楚几点
（1）如何去连接操作ACCESS数据库？至少要知道如何把ACCESS数据库中表中你所要的数据读出来。
（2）根据你要生成树状结构的要求，分析如何使用循环语句把你的数据写入？
上面弄清楚了就知道了。
给你一段连接SQLSERVER的
SqlConnection myconn=new SqlConnection(连接串);
SqlCommand cmd=new SqlCommand(sql语句,myconn);
myconn.Open();
SqlDataReader rdr=cmd.ExcuteReader();
while (rdr.Read())
{
取数据
string strTemp:=rdr['name'].ToString().Trim(); //name是字段名
}
myconn.Close;

Access 数据库
string ConnString ="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Application.StartupPath+ @"\数据库.mdb;Persist Security Info=False;Jet OLEDB:USERID=你的名字;Database Password=你的密码";
OleDbDataAdapter Cmd ;
Cmd = new OleDbDataAdapter("select * from "+Table,ConnString);
DataSet ds = new DataSet();
Cmd.Fill(ds);
ds.Table[0] 就是你要的Table
