ASP.NET C＃在电子邮件中插入Html代码

Question

我无法理解一个事实... 我创建了一个表单来发送电子邮件，它非常好。 现在我已经扩展了ajax控件工具包的扩展html文本框，并且当我收到电子邮件时，我没有看到所有的代码...我举个例子。 我已将此：

<table><tbody><tr><td rowspan="2"> </td><td><b>LA QUALITA' ALPITOUR</b></td></tr><tr><td> </td></tr></tbody></table>

，并在电子邮件我只看到文字加粗了，其他所有的代码编写，并可见......为什么？ 我希望我已经解释了我的问题......我不是英语，我写得也不好。

如果需要的话，这是我的后台代码：

protected void Btn_SendMail_Click(object sender, EventArgs e) 
{ 
    MailMessage msg = new MailMessage(); 
    msg.From = new MailAddress("danieleluciani92@gmail.com"); 
    msg.To.Add("danieleluciani92@gmail.com"); 
    msg.Subject = txtSubject.Text; 
    msg.IsBodyHtml = true; 
    msg.Body = txtBody.Text; 
    SmtpClient sc = new SmtpClient("smtp.gmail.com"); 
    sc.Port = 25; 
    sc.Credentials = new NetworkCredential("danieleluciani92@gmail.com", "Dead2006!"); 
    sc.EnableSsl = true; 
    sc.Send(msg); 
    Response.Write("<script>alert('ennamo');</script>"); 
} 

，这是我的HTML/ASP代码：

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server"> 
<span class="fontS">A: 
    <asp:TextBox ID="txtTo" runat="server" Font-Size="X-Small" ReadOnly="True">Tutti Gli Utenti</asp:TextBox> 
    <br /> 
    Oggetto: 
    <asp:TextBox ID="txtSubject" runat="server" Font-Size="X-Small" /><br /> 
    <asp:ScriptManager ID="ScriptManager1" runat="server" /> 
    </span> 
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
    <ContentTemplate> 
     <span class="fontS">Tipo di Email:</span><asp:DropDownList ID="DropDownList1" runat="server" Font-Size="X-Small" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"> 
      <asp:ListItem Selected="True">Testo Libero</asp:ListItem> 
      <asp:ListItem>Email Con Offerte</asp:ListItem> 
     </asp:DropDownList> 
     <br /> 
     <asp:CheckBoxList ID="CheckBoxList1" runat="server" Visible="False" AutoPostBack="True" OnSelectedIndexChanged="CheckBoxList1_SelectedIndexChanged"> 
     </asp:CheckBoxList> 
     <br /> 
     <asp:TextBox ID="txtBody" runat="server" Height="550px" TextMode="MultiLine" Width="900px" /> 
     <asp:HtmlEditorExtender ID="txtBody_HtmlEditorExtender" runat="server" TargetControlID="txtBody" EnableSanitization="False"> 
     </asp:HtmlEditorExtender> 
    </ContentTemplate> 
</asp:UpdatePanel> 
<br /> 
<asp:Button ID="Btn_SendMail" runat="server" OnClick="Btn_SendMail_Click" Text="Invia" /><br />

您需要将电子邮件的内容类型定义为text/html，并使用AlternateView，您可以将电子邮件作为文本和html发送。你只需要添加的text/htmlContentType作为不同的观点，这样的：

protected void Btn_SendMail_Click(object sender, EventArgs e) 
{ 
    MailMessage msg = new MailMessage(); 

    ContentType mimeType = new System.Net.Mime.ContentType("text/html"); 
    // Decode the html in the txtBody TextBox...  
    string body = HttpUtility.HtmlDecode(txtBody.Text); 
    AlternateView alternate = AlternateView.CreateAlternateViewFromString(body, mimeType); 
    msg.AlternateViews.Add(alternate); 

    msg.From = new MailAddress("danieleluciani92@gmail.com"); 
    msg.To.Add("danieleluciani92@gmail.com"); 
    msg.Subject = txtSubject.Text; 
    msg.IsBodyHtml = true; 
    msg.Body = body; 
    SmtpClient sc = new SmtpClient("smtp.gmail.com"); 
    sc.Port = 25; 
    sc.Credentials = new NetworkCredential("danieleluciani92@gmail.com", "Dead2006!"); 
    sc.EnableSsl = true; 
    sc.Send(msg); 
    Response.Write("<script>alert('ennamo');</script>"); 
}
