Question

現在、ドキュメントからXMLを取得し、ウェブページに表示するアップロードシステムを作成しています。

私が直面している問題は、WebサイトのXML抽出部分を追加するたびに、タイトルに記載されているエラーがコンパイラによって返されることです。私はすでにWindowsBaseを手動で、そしてドロップダウンメニューから追加しました。

私のコードは現在のようです。

<script runat="server">

    //or shown at the same time. The buttons are being added so we can test whether they will
