在ASP.NET 2.0中,有时候需要对ASP.NET生成的HTML代码进行处理,或者是保存成静态文件。ASP.NET 提供了直接将请求保存成文件的方法:HttpRequest.SaveAs方法。下面这个方法就是在ASP.NET 2.0中得到ASP.NET生成的HTML代码,同时,生成一个静态文件的方法。
VB.NET

<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("学生班级", GetType(System.String)))
dt.Columns.Add(New System.Data.DataColumn("学生姓名", GetType(System.String)))
dt.Columns.Add(New System.Data.DataColumn("语文", GetType(System.Decimal)))
dt.Columns.Add(New System.Data.DataColumn("数学", GetType(System.Decimal)))
dt.Columns.Add(New System.Data.DataColumn("英语", GetType(System.Decimal)))
dt.Columns.Add(New System.Data.DataColumn("计算机", 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) = "班级" + 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()
