好的，这就是我到目前为止所拥有的。我不知道在哪里放我的电子邮件地址，也不知道有什么错误。它不断传达信息。

我的content.aspx页面：

<%@ Page Title="Contact" Language="C#" MasterPageFile="~/Site.Master"  AutoEventWireup="true" CodeBehind="Contact.aspx.cs" Inherits="JeremiahTorresportfoliov1.Contact"%>


<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">

<hgroup class="title">
    <h2>How to get in touch</h2>
</hgroup>

<section class="contact">

        <h3>Phone:</h3>

您无法从控件继承表单，它应该来自System.Web.UI.Page。添加usercontrol并将所有标记和代码移动到该控件：

<强> MyUserControl.ascx： 

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyUserControl.ascx.cs" Inherits="JeremiahTorresportfoliov1.MyUserControl" %>

<div class="focus" >

            Text="Send" ValidationGroup="ContactValidation" OnClick="btnSubmit_Click" />
    </li>
</ul>

<强> MyUserControl.ascx.cs：

    public partial class MyUserControl : System.Web.UI.UserControl

        email.To.Add(new MailAddress(FromEmail));
        email.Subject = Subject;
        email.IsBodyHtml = true;

        //build the body
        var sBody = new StringBuilder();
        sBody.Append("<strong>Contact Details</strong><br /><br />");

}


    }
}

将此控件添加到您的页面并修复代码。

<强> Contact.aspx： 

<%@ Page Title="Contact" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Contact.aspx.cs" Inherits="JeremiahTorresportfoliov1.Contact" %>

<%@ Register Src="~/MyUserControl.ascx" TagPrefix="uc1" TagName="MyUserControl" %>


<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">
    <uc1:MyUserControl runat="server" id="MyUserControl" />
</asp:Content>

<强> Contact.aspx.cs： 

namespace JeremiahTorresportfoliov1
{
    public partial class Contact : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
    }
}

更新：我在您的更新中看到您仍然有错误。在MyUserControl.ascx.cs中更改此内容：

public class MyUserControl : System.Web.UI.UserControl

到此：

public partial class MyUserControl : System.Web.UI.UserControl

在Contact.aspx中，将对Myusercontrol的引用移到页面顶部，如下所示：

<%@ Page Title="Contact" Language="C#" MasterPageFile="~/Site.Master"  AutoEventWireup="true" CodeBehind="Contact.aspx.cs" Inherits="JeremiahTorresportfoliov1.Contact"%>

<%@ Register Src="~/MyUserControl.ascx" TagPrefix="uc1" TagName="MyUserControl" %>
<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">
