c# - Web コントロールのバックエンドをコントロール自体に追加しますか?

Question

現在、このコントロールの Web コントロールとバックエンド コードがあります (デザイナーなども同様です)。

これをマクロとして Umbraco にアップロードするには、これをすべて 1 つのファイルにまとめる必要があります。何かを壊さずにどうすればこれを実現できますか？現在、コードをコピーしてタグを付けて貼り付けると、他のすべてとifが壊れます。

ウェブフォーム

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

    <form id="UploadForm" runat="server">
<asp:FileUpload id="FileUploadControl" runat="server" />
    <asp:Button runat="server" id="UploadButton" text="Upload" onclick="UploadButton_Click" />
    <br /><br />
    <asp:Label runat="server" id="StatusLabel" text="Upload status: " />
</form>

そしてユーザーコントロールのバックエンド
