推荐答案

您可以使用以下方法.这将适用于所有aspx页面(包括任何asp.net控件)

Hi,
you can use the following method. This will work for all aspx pages(which includes any asp.net controls)

private string GetHTMLContent()
        {
            StringWriter sw = new StringWriter();
            HtmlTextWriter w = new HtmlTextWriter(sw);
            //divHTMLWrapper is a div, which we set to runat 'server' and in this DIV the whole controls include
            divHTMLWrapper.RenderControl(w);
            string htmlString = sw.GetStringBuilder().ToString();
        }

//您必须在代码文件中声明此函数

// You must declare this function in the code file

public override void VerifyRenderingInServerForm(Control control)
    {
    }

aspx页面将如下所示.您的aspx控件应位于"divHTMLWrapper"中

The aspx page will look like this. Your aspx controls should be in "divHTMLWrapper"

<form id="form1" runat="server">
<pre lang="xml">
    <div id="divHTMLWrapper" runat="server">
    <div  style="width: 100%; background-position: center center;">
    <div style="margin:auto; width:280px">
    <img runat="server" src="images/logo_new.jpg" style="text-align:center" /></div>
    </div>

</div
</form>

</div
</form>

这并不难.您需要做的就是使用流读取器或任何文件读取机制，打开aspx文件，将其读取到字符串变量中，然后将其传递到所需的任何位置.

代码示例如下:

StreamReader sr =新的StreamReader("FILE PATH");
字符串strText = sr.ReadToEnd();
sr.Close();

Hi,

That isn''t hard to do. All you need to do is using stream reader or any file reading mechanism, open the aspx file, read it into a string variable and pass it wherever you want.

Code sample is as below:

StreamReader sr = new StreamReader("FILE PATH");
string strText = sr.ReadToEnd();
sr.Close();
