目标是上传 .ppt，将其转换为 .pdf，然后将其显示给用户。
现在我可以上传和转换就好了。如果我在代码隐藏中取消注释这两行，它将显示全屏显示。
有什么方法可以在“asp：Image”或其他非全屏内容中显示 .pdf？
我的正面是这样的：
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<input type="file" id=File1 name=File1 runat="server" />
<asp:Button id="b1" Text="Upload" OnCLick="DoUpload" runat="server" />
<asp:Image ID="img" runat="server" AlternateText="" Width="400" Height="400" />
</asp:Content>
我的代码隐藏是这个
