本人用VB.net做的XML添加数据文件,为什么会自动把 encoding="utf-8"清楚掉
导致添加的XML数据不支持汉字,请大虾帮忙指导
文件名字add.aspx
<%@ Page Language="VB" AutoEventWireup="false" %>
<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.Data" %>
<script runat="server">
Protected Sub AddClick(ByVal sender As Object, ByVal e As System.EventArgs)
Try
Dim dataFile As String = "gbook.xml"
'the next line wraps
Dim fin As New FileStream(Server.MapPath(dataFile), FileMode.Open, FileAccess.Read, FileShare.ReadWrite)
'this line also wraps
Dim fout As New FileStream(Server.MapPath(dataFile), FileMode.Open, FileAccess.Write, FileShare.ReadWrite)
Dim guestData As New DataSet()
Dim newRow As DataRow
err.Text = ""
guestData.ReadXml(fin)
fin.Close()
newRow = guestData.Tables(0).NewRow()
newRow("Name") = Name.Text
newRow("Chrono") = DateTime.Now.ToString()
newRow("Email") = Email.Text
newRow("Comments") = Comments.Text
guestData.Tables(0).Rows.Add(newRow)
guestData.WriteXml(fout, XmlWriteMode.WriteSchema)
fout.Close()
pnlAdd.Visible = False
pnlThank.Visible = True
Catch edd As Exception
err.Text = "Error Writing file at:" & edd.ToString()
End Try
End Sub
