推荐答案

首先我想谈谈下载文件，在ASP.NET中，您可以使用以下代码让客户端下载文件。

First I would like to talk about downloading the files, in ASP.NET, you can use this following code to let the client download the file.

// Provided you wanted to share the name in the QueryString
var file = Server.MapPath("~/documents/" + Request["doc"]);
Response.AppendHeader("content-disposition", "attachment; filename=" + Request["doc"]);
Response.ContentType = "application/octet-stream";
// Transmit file
Response.TransmitFile(file);

然后，为了查看文件内容，有很多方法，如果文件是PDF，那么你需要使用一些PDF阅读器，如果文件是Word文档然后是Word阅读器。第三方开发人员有很多.NET库让你阅读这些文件的内容，并将它们作为简单的痛苦文本（但带有样式）写在屏幕上。其中一个库是 iTextSharp [ ^ ]。有类似的更多库可以让您查看文件的内容。如果您使用iTextSharp，那么以下链接可以帮助您。

还有很多其他库和解决方案。当你需要它时，请记住谷歌。 ：）

Then, for viewing the file content there are a lot of methods, if the file is PDF, then you would need to use some PDF reader, if the file is Word document then a Word reader. There are quite a lot of .NET libraries by third-party developers to let you read the content of these files and write them on the screen as simple pain text (but with styles). One of such libraries is iTextSharp[^]. There are similar more libraries to let you view the content of files. If you would use iTextSharp, then the following links would help you out.

There are a lot of other libraries and solution out there. Do remember to Google for them when you need them. :)
