问题描述

如何在不要求将Excel安装在运行代码的计算机上的情况下使用C＃创建Excel电子表格？

How can I create an Excel spreadsheet with C# without requiring Excel to be installed on the machine that's running the code?

推荐答案

您可以使用一个名为ExcelLibrary的库。这是发布在Google代码上的免费开放源代码库：

You can use a library called ExcelLibrary. It's a free, open source library posted on Google Code:

ExcelLibrary

这似乎是您上面提到的PHP ExcelWriter的端口。它不会写入新的.xlsx格式，但是他们正在努力添加该功能。

This looks to be a port of the PHP ExcelWriter that you mentioned above. It will not write to the new .xlsx format yet, but they are working on adding that functionality in.

它非常简单，小巧且易于使用。另外，它还有一个DataSetHelper，可让您使用数据集和数据表轻松处理Excel数据。

It's very simple, small and easy to use. Plus it has a DataSetHelper that lets you use DataSets and DataTables to easily work with Excel data.

ExcelLibrary似乎仍然只适用于较旧的Excel格式（.xls文件） ，但将来可能会增加对较新的2007/2010格式的支持。

ExcelLibrary seems to still only work for the older Excel format (.xls files), but may be adding support in the future for newer 2007/2010 formats.

您也可以使用 EPPlus 仅适用于Excel 2007/2010格式的文件（.xlsx文件）。还有 NPOI 可以同时使用。

You can also use EPPlus, which works only for Excel 2007/2010 format files (.xlsx files). There's also NPOI which works with both.

如注释中所述，每个库都有一些已知的错误。总之，随着时间的流逝，EPPlus似乎是最佳选择。

There are a few known bugs with each library as noted in the comments. In all, EPPlus seems to be the best choice as time goes on. It seems to be more actively updated and documented as well.

此外，正如下面的@АртёмЦарионов所指出的那样，EPPlus支持数据透视表，而ExcelLibrary可能会提供一些支持（< a href = https://code.google.com/archive/p/excellibrary/issues/98 rel = noreferrer> ExcelLibrary中的数据透视表问题）

Also, as noted by @АртёмЦарионов below, EPPlus has support for Pivot Tables and ExcelLibrary may have some support (Pivot table issue in ExcelLibrary)

这里有几个链接供快速参考：

ExcelLibrary - GNU较小的GPL

EPPlus - GNU通用公共许可证（LGPL）

NPOI - Apache许可

Here are a couple links for quick reference:

EPPlus - GNU Lesser General Public License (LGPL)
NPOI - Apache License

这里有一些例子ExcelLibrary的代码：

这里是一个从数据库中获取数据并从中创建工作簿的示例。请注意，ExcelLibrary代码是底部的单行：

Here is an example taking data from a database and creating a workbook from it. Note that the ExcelLibrary code is the single line at the bottom:

//Create the data set and table
DataSet ds = new DataSet("New_DataSet");
DataTable dt = new DataTable("New_DataTable");

//Set the locale for each
ds.Locale = System.Threading.Thread.CurrentThread.CurrentCulture;
dt.Locale = System.Threading.Thread.CurrentThread.CurrentCulture;

//Open a DB connection (in this example with OleDB)
OleDbConnection con = new OleDbConnection(dbConnectionString);
con.Open();

//Create a query and fill the data table with the data from the DB
string sql = "SELECT Whatever FROM MyDBTable;";
OleDbCommand cmd = new OleDbCommand(sql, con);
OleDbDataAdapter adptr = new OleDbDataAdapter();

adptr.SelectCommand = cmd;
adptr.Fill(dt);
con.Close();

//Add the table to the data set
ds.Tables.Add(dt);

//Here's the easy part. Create the Excel worksheet from the data set
ExcelLibrary.DataSetHelper.CreateWorkbook("MyExcelFile.xls", ds);

创建Excel文件非常简单。您也可以手动创建Excel文件，但是上述功能确实让我印象深刻。

Creating the Excel file is as easy as that. You can also manually create Excel files, but the above functionality is what really impressed me.
