DataView中实现模糊查询，定位

查询：
dv.RowFilter="FirstName like 'A%'";是可以的.

 SqlConnection con=new SqlConnection("workstation id=yio;packet size=4096;user id=sa;data source=yio;persist security info=True;initial catalog=Northwind");
   SqlDataAdapter da=new SqlDataAdapter("select * from Employees",con);
   DataTable dt=new DataTable();
   da.Fill(dt);
   DataView dv=new DataView(dt);
   dv.RowFilter="FirstName like 'A%'";
   DataGrid1.DataSource=dv;
   DataBind();

定位：

DataView.Find()
