C#读取Excel文件

Question

如何打开和读取 excel 文件中的所有数据以执行一些操作，例如将它们写入数据库...

Answer 1

You can use the default library that comes with the .NET framework in order to use the Excel.Application Object and therefore the Workbook and Worksheets objects, so you can access Excel files, read or manipulate them

You can add it to your project by using the Add Reference option, the library is called

Microsoft.Office.Interop.Excel

Hope this helps

Answer 2

Assuming that the Excel files are in a table format, I'd suggest that the best way would be using OleDB. This page has a very basic sample that should show you how to get started.

If you're unable to use OleDB for some reason, then you could use Excel Automation. This is not recommended if it's on a server though and will in general be slower and less stable than OleDB, but you will be able to do pretty much anything you need.

Answer 3

您可以使用 com 自动化http://support.microsoft.com/kb/302096自动化 Excel，但如果您在网络服务器上，则需要使用第三方库，如http://sourceforge.net/projects/koogra /

Answer 4

There are several ways:

• If *.xslx (the new XML based format) is used, you can open that file and read the XML File
• You can read it with Excel COM Interop (not recomended on a Server!)
• You can use a ODBC Data Source

Answer 5

Starting with Office 2007, you can use OpenXML to query/manipulate office documents. The .xlsx files (all Office .???x files) are zipped up XML files.

Answer 6

ExcelToEnumerable is a great solution if you want to map Excel data to a list of classes, eg:

var filePath = "/Path/To/ExcelFile.xlsx";
IEnumerable<MyClass> myClasses = filePath.ExcelToEnumerable<MyClass>();
