如果没有安装excel，有没有办法打开和读取excel文件？ [英] Is there any way to open and read a excel file if excel is not installed ?

问题描述

我想打开一个excel文件并在我的机器上没有安装excel时读取它。

解决方案

你可以打开任何文件而不需要程序创建它已安装：

  byte  [] data = File.ReadAllBytes（pathToFile）; 

将在大多数情况下执行此操作。

问题在于理解它并显示数据。



想一想：a网站只会发布一个HTML流：您可以阅读并找出网站的外观 - 或者您可以将该HTML提供给浏览器应用程序，它将为您完成。后者更快更简单！ ：笑：



与Excel相同：您可以阅读该文件，但除非您的软件理解Excel数据格式（并且已经存在大量的数据格式）年）你不能轻易对数据做任何事情。您需要安装Excel，或使用可以读取Excel数据的库以便使用该信息。 Google可以帮助您找到合适的图书馆 - 我不知道您要做什么或者您的优先级是什么，所以最好自己开始搜索。

您可以在C＃中安装Microsoft Excel时读写Excel文档：

解决方案

You can "open" any file without the program that created it installed:

byte[] data = File.ReadAllBytes(pathToFile);

will do it for most situations.
The problem is in understanding it, and displaying data.

Think about it: a website just emits a stream of HTML: which you can read and work out what the website looks like - or you can feed that HTML into a browser application and it will do it for you. The latter is a lot quicker and simpler! :laugh:

It's the same with Excel: you can read the file, but unless your software understands Excel data format (and there have been a number of them over the years) you can't easily do anything with the data. You need to install Excel, or use a library which can read Excel data in order to use the information. Google can help you find an appropriate library - I have no idea what you are trying to do or what your priorities are, so it's best if you start searching yourself.

This article[^] should get you going without the need to install Excel on the target computer.

You can read and write Excel documents without Microsoft Excel installed in C#:
