在ASP.NET 2.0中,有時候需要對ASP.NET生成的HTML代碼進(jìn)行處理,或者是保存成靜態(tài)文件。ASP.NET 提供了直接將請求保存成文件的方法:HttpRequest.SaveAs方法。下面這個方法就是在ASP.NET 2.0中得到ASP.NET生成的HTML代碼,同時,生成一個靜態(tài)文件的方法。 VB.NET <%@ Page Language="VB" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www./TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> Function CreateDataSource() As ICollection Dim dt As System.Data.DataTable = New System.Data.DataTable Dim dr As System.Data.DataRow dt.Columns.Add(New System.Data.DataColumn("學(xué)生班級", GetType(System.String))) dt.Columns.Add(New System.Data.DataColumn("學(xué)生姓名", GetType(System.String))) dt.Columns.Add(New System.Data.DataColumn("語文", GetType(System.Decimal))) dt.Columns.Add(New System.Data.DataColumn("數(shù)學(xué)", GetType(System.Decimal))) dt.Columns.Add(New System.Data.DataColumn("英語", GetType(System.Decimal))) dt.Columns.Add(New System.Data.DataColumn("計(jì)算機(jī)", GetType(System.Decimal))) Dim i As Integer = 0 For i = 0 To 50 - 1 Dim rd As System.Random = New System.Random(Environment.TickCount * i) dr = dt.NewRow dr(0) = "班級" + i.ToString dr(1) = "【孟子E章】" + i.ToString dr(2) = System.Math.Round(rd.NextDouble * 100, 2) dr(3) = System.Math.Round(rd.NextDouble * 100, 2) dr(4) = System.Math.Round(rd.NextDouble * 100, 2) dr(5) = System.Math.Round(rd.NextDouble * 100, 2) dt.Rows.Add(dr) Next Dim dv As System.Data.DataView = New System.Data.DataView(dt) Return dv End Function Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) If Not IsPostBack Then GridView1.DataSource = CreateDataSource() GridView1.DataBind() End If End Sub Protected Overloads Overrides Sub Render(ByVal writer As HtmlTextWriter) Dim html As System.IO.StringWriter = New System.IO.StringWriter Dim tw As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(html) MyBase.Render(tw) Dim sw As System.IO.StreamWriter sw = New System.IO.StreamWriter(Server.MapPath("a.htm"), False, System.Text.Encoding.Default) sw.Write(html.ToString) sw.Close() tw.Close() Response.Write(html.ToString) End sub </script> <html xmlns="http://www./1999/xhtml"> <head> <title>得到ASP.NET生成的HTML</title> </head> <body> <form id="Form1" runat="server"> <asp:GridView ID="GridView1" runat="server" Font-Size="12px" BackColor="#FFFFFF" GridLines="Both" CellPadding="4" Width="560"> <HeaderStyle BackColor="#EDEDED" Height="26px" /> </asp:GridView> </form> </body> </html> 轉(zhuǎn)帖于 Xue163.com_VB.NET |
