Question

我需要澄清天气，我可以将网页保存到 stringbuilder ，还是将按钮点击的字符串保存为HTML

我的HTML页面是

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
</head>
<body>
    <form id="form2" runat="server">
   <div onload="disableBackButton();">


    <table align="center" width="100%" cellpadding="0" cellspacing="0">

    <tr>
    <td>


        <table align="center" width="100%" cellpadding="0" cellspacing="0">
        <tr>
                <td> 

                        <div style="padding: 5px; cursor: pointer; vertical-align: middle;">
                            <div style="float: left; font-size:large; color:Blue; width: 358px;">

                            <div style="float: left; margin-left: 20px;">

                            <div style="float: right; vertical-align: middle;">
                             </div>
                        </div>

                </td>
            </tr>
            <tr>

        <td align="center" width="100px" height="35px">
            <asp:RadioButton ID="RadioButton1" CssClass="scaledRadioButton" runat="server" GroupName="Question1"

            </td> 
            <td align="left"  width="100px" height="45px">

                    GroupName="Question1" Text="No" 
                    Font-Size="12px" CssClass="scaledRadioButton" Height="20px" Width="49px"/>
       </td>

        </tr>
         </table>





    </div>
    </form>
</body>
</html>

在代码后面我绑定了加载中数据库端的值像这样

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim xmldoc As New XmlDocument
                    Dim xmldata As String = "<data><rdBx1>True</rdBx1></data>"
        Dim stringReader As New StringReader(kioskxml)
        xmldoc.Load(stringReader)
        stringReader.Dispose()

        If (XmlNodeNavigator.InitializeXmlNodeNavigator(xmldata)) Then

            Dim Q1 As String = XmlNodeNavigator.RetrieveElementValue("//data/rdBx1")
            If (Q1 = "True") Then
                RdbtnQ1Yes.Checked = True

            Else
                RdBtnQ1No.Checked = True
            End If


        End If

    End Sub

现在我想在数据库中单击按钮时将此数据绑定页面保存为html 谢谢

如果我了解更多或更少，必须是页面的渲染方法

string GetInnerHtml()
    {
        using (System.IO.StringWriter sw = new System.IO.StringWriter())
        {
            using (HtmlTextWriter htmlWriter = new HtmlTextWriter(sw))
            {
                Page.RenderChildren(htmlWriter);
                return sw.ToString();
            }
        }
    }

VB.NET版

    Function GetInnerHtml() As String
        Using sw As New IO.StringWriter
            Using htmlWriter As New HtmlTextWriter(sw)
                Page.RenderChildren(htmlWriter)
                Return sw.ToString()
            End Using
        End Using
    End Function

如何使用

public partial class _Default : Page
{

    protected override void Render(HtmlTextWriter writer)
    {
        var html = GetInnerHtml();

         //Use html string

        Response.Write(html);
    }


    string GetInnerHtml()
    {
        using (System.IO.StringWriter sw = new System.IO.StringWriter())
        {
            using (HtmlTextWriter htmlWriter = new HtmlTextWriter(sw))
            {
                RenderChildren(htmlWriter);
                return sw.ToString();
            }
        }
    }
}

使用vb.net，您可以使用以下代码获取页面/网址的前端代码：

    Dim sourceString As new StringBuilder 
    sourceString.Append(CStr(New System.Net.WebClient().DownloadString(Request.PhysicalPath)))

Request.PhysicalPath将提供当前查看页面的地址

将当前网页保存为字符串，其中包含标签中的数据
