这里如何得到最后一页呢？
[解决办法]
计算出总条数，除以每页的条数，
[解决办法]
ds.Table[0].Rows.Count就是总数了 / 每页显示多少，这个你控制
另外 SqlCommand Command = new SqlCommand(Sqlstr, objConn);
System.Data.SqlClient.SqlDataAdapter objCommand = new System.Data.SqlClient.SqlDataAdapter(Command);
这里改改
SqlDataAdapter da = new SqlDataAdapter(Sqlstr，objConn);
直接这样就行了，不用开关数据库，记得用完释放
