DataTable排序筛选

代码如下：

Dim dv As New DataView(dt)
dv.Sort = "bla"
dv.RowFilter = "bla = 1"  '更多.net源码和教程，来自[乐 博 网 www.lob.cn]
Dim dtnew As DataTable = dt.Clone
For Each dvr As DataRowView In dv
dtnew.ImportRow(dvr.Row)
Next
dt.Clear()
dt = dtnew.Copy
DataTable.DefaultView.Sort = "id desc"，这个是按照ID列倒序排列的，语法就是SQLWhere后面的子查询的语法。
