推荐答案

这不是一个简单或简单的解决方案。除了MHT之外，那些专有的文件格式并不打算在浏览器中显示。



我将从你需要的每个文件生成器开始查看，但我怀疑你会有多少运气。

This is not an easy or trivial solutions. Save for the MHT those are proprietary file formats that are not meant to be displayed in a browser.

I would start with each of the producers of the files you needing to view, but I doubt you will have much luck.

首先，你没有像你描述的那样预览PDF，Adobe Acrobat Reader有一个插件，由浏览器显示PDF的内容。同样，Chrome拥有自己的PDF阅读器。

您可以使用不同的插件在应用程序中嵌入不同的查看器。但是你需要在客户端安装它们。



但这种方法无法预览。它既不是跨浏览器，也不是跨平台的。而且，随着HTML5进入无插件方向，它也不具备前瞻性。



如果你真的需要预览，你需要渲染那些文件作为服务器上的图像并将该图像发送给客户端。



我建议你找一些商业库或命令行工具，你可以在asp上调用.net服务器端来自c＃，并在上传这些文件时创建实际预览图像（PNG）。使用TIFF，你不需要.net支持的东西，所以你有把它转换成png的所有东西。



你可以尝试找到免费/开源工具，但我怀疑你会发现任何。

这些是一些商业选择：

First of all, you don't "preview" PDF's the way you described, Adobe Acrobat Reader has a plugin that is instanciated by the browser to show the content of the PDF. Likewise, Chrome has it's own PDF reader.
You can use different plugins to "embed" the different viewers in your application. But you will need to install them all on the client side.

But this approach is no preview. And neither is it cross-browser, or cross-platform. And as HTML5 goes in a plugin-less direction, it is not future-proof either.

If you really need a preview, you need to render those files as image on the server and send that image to the client.

I suggets you look for some commercial library or command line tool, that you can call on asp.net server side from c# and create actual preview images (PNG) at the time those files are uploaded. With TIFF you don't need such thing as it is supported by .net, so you have everything to convert it to png.

You can try to find free/open source tools for that, but I doubt you will find any.
