Overview  概览​

Excel-DNA is an independent project to integrate .NET into Excel. We hope it will be useful to Excel users who currently write VBA code for functions and macros, and would like to start using .NET. Also interested would be C/C++ based .xll add-in developers who want to use the .NET framework to develop their add-ins.
Excel-DNA 是一个将.NET 集成到 Excel 中的独立项目。我们希望它对目前使用 VBA 编写函数和宏的 Excel 用户以及希望开始使用.NET 的用户有用。此外，对使用.NET 框架开发其附加组件的 C/C++基于.xll 的附加组件开发人员也可能感兴趣。

(For a bit more background about .NET and Excel-DNA, see What and why? - An introduction to .NET and Excel-DNA.
(为了更多关于.NET 和 Excel-DNA 的背景信息，请参见 What and why? - .NET 和 Excel-DNA 的介绍。)

The Excel-DNA Runtime is free for all use, and distributed under a permissive open-source license that also allows commercial use.
Excel-DNA 运行时免费用于所有用途，并以允许商业使用的宽松开源许可证分发。

Excel-DNA is developed using .NET, and users have to install the freely available .NET Framework runtime. The integration is by an Excel Add-In (.xll) that exposes .NET code to Excel. The user code can be in text-based (.dna) script files (C#, Visual Basic or F#), or compiled .NET libraries (.dll). Excel-DNA supports both the .NET runtime version 2.0 (which is used by .NET versions 2.0, 3.0 and 3.5) and version 4. Add-ins can target either version of the runtime, and concurrent loading of both runtime versions into an Excel instance is supported.
Excel-DNA 使用.NET 开发，用户需要安装免费提供的.NET 框架运行时。通过 Excel 插件(.xll)进行集成，该插件将.NET 代码暴露给 Excel。用户代码可以是基于文本的(.dna)脚本文件（C#、Visual Basic 或 F#），或编译的.NET 库(.dll)。Excel-DNA 支持.NET 运行时版本 2.0（用于.NET 版本 2.0、3.0 和 3.5）和版本 4。插件可以针对这两种运行时版本中的任意一种进行开发，并且 Excel 实例中同时加载这两种运行时版本是支持的。

Excel versions '97 through 2016 can be targeted with a single add-in. Advanced Excel features are supported, including multi-threaded recalculation (Excel 2007 and later), registration-free RTD servers (Excel 2002 and later) and customized Ribbon interfaces (Excel 2007 and 2010). There is support for integrated Custom Task Panes (Excel 2007 and later), offloading UDF computations to a Windows HPC cluster (Excel 2010 and later), and for the 64-bit versions of Excel 2010 and 2013.
Excel 97 至 2016 版本可以通过一个插件进行目标定位。支持高级 Excel 功能，包括多线程重算（Excel 2007 及以后版本），注册免费 RTD 服务器（Excel 2002 及以后版本）和自定义 Ribbon 界面（Excel 2007 和 2010）。支持集成自定义任务窗格（Excel 2007 及以后版本），将 UDF 计算卸载到 Windows HPC 群集（Excel 2010 及以后版本），以及 Excel 2010 和 2013 的 64 位版本。

Most managed UDF assemblies developed for Excel Services can be exposed to the Excel client with no modification. (Please contact us if you are interested in this feature)
大多数为 Excel Services 开发的托管 UDF 程序集可以直接暴露给 Excel 客户端，无需修改。（如有兴趣，请联系我们）

The latest release - Excel-DNA Latest - includes support for both RTD-based asynchronous worksheet functions (Excel 2002 and later) and native Excel asynchronous functions (Excel 2010 and later). The RTD-based asynchronous support is designed to (optionally) integrate with the .NET 4.0 Task-based operations, as well as the Reactive Extensions library, allowing IObservables to be exposed as 'live' worksheet UDFs - (thus 'RxExcel'). The language-specific support for asynchronous functions in C# 5, Visual Basic 11 and F# 2.0 can be easily integrated with the Excel-DNA asynchronous interfaces.
最新的发布 - Excel-DNA Latest - 包括对基于 RTD 的异步工作表函数（Excel 2002 及以后版本）和原生 Excel 异步函数（Excel 2010 及以后版本）的支持。基于 RTD 的异步支持旨在（可选地）与.NET 4.0 的任务操作以及 Reactive Extensions 库集成，允许将 IObservables 暴露为“实时”的工作表 UDF - （因此是“RxExcel”）。C# 5、Visual Basic 11 和 F# 2.0 中的异步函数语言特定支持可以轻松与 Excel-DNA 异步接口集成。

Are there no other ways to create Excel add-ins with .NET? Why should I use Excel-DNA?
使用.NET 创建 Excel 插件还有其他方法吗？为什么我应该使用 Excel-DNA？​

There are a few different ways of making Excel add-ins with .NET, but Excel-DNA has unique advantages. For starters, these are the different kinds of Excel add-ins that can be created with .NET:
使用.NET 创建 Excel 插件有几种不同的方法，但 Excel-DNA 具有独特的优势。首先，这些是使用.NET 可以创建的不同类型的 Excel 插件：

  • VSTO
  • COM add-in  COM 插件
  • C API
  • Other libraries (e.g. NetOffice, Add-In Express, FCell)
    其他库（例如 NetOffice、Add-In Express、FCell）

Where does Excel-DNA fit in?
Excel-DNA 处于什么位置？

Excel-DNA brings together all three parts that are needed to make a great Excel add-in with .NET - the native Excel C API, the COM object model and the .NET runtime.
Excel-DNA 将所有三部分结合在一起，使 Excel .NET 模块成为优秀的 Excel 插件 - 原生 Excel C API、COM 对象模型和 .NET 运行时。

Should I not just stick to the official Microsoft tools for making Excel add-ins, rather than relying on a third-party tool?
我应该仅仅依赖微软官方的工具来制作 Excel 插件，而不是依赖第三方工具吗？​

Using only Microsoft's tools makes it hard to create powerful and full-featured Excel add-ins with .NET that work in different Excel versions, and that are easy to deploy. Some of the problems are:
仅使用微软的工具很难创建具有强大功能和完整功能的 Excel .NET 插件，这些插件可以在不同的 Excel 版本中工作，并且易于部署。其中一些问题是：

  • Microsoft has no official support for using the native Excel C API in .NET add-ins
    微软没有官方支持在 .NET 插件中使用原生 Excel C API
  • VSTO has no support for making user-defined worksheet functions
    VSTO 没有支持用户定义的工作表函数
  • Automation add-ins can provide UDF, but have poor performance, and allow limited customization
    自动化加载项可以提供 UDF，但性能较差，并且允许的自定义有限
  • VSTO and regular COM-based add-ins require administrative rights to install
    VSTO 和基于常规 COM 的加载项需要管理员权限才能安装

What if I want to make an Excel add-in with Python, C or C++?
如果我想用 Python、C 或 C++制作一个 Excel 加载项呢？

Excel-DNA is used for making Excel add-ins with .NET. For alternative programming languages, there are similar libraries that integrate with the native Excel C API, such as:
Excel-DNA 用于制作基于 .NET 的 Excel 插件。对于其他编程语言，有类似库可以与原生 Excel C API 集成，例如：

  • Python: PyXLL
  • C/C++: Xlw, XLL+
  • Modern C++: xll8.  现代 C++: xll8.

What about VBA? Can Excel-DNA help me use my current VBA skills and still move to .NET?
VBA 呢？Excel-DNA 能否帮助我利用现有的 VBA 技能，同时转向.NET？​

VB.NET is the newest member of the Visual Basic family. While sometimes overshadowed in popularity by C#, VB.NET is as powerful as C# (sometimes more!), can access all the same .NET libraries, and is fully supported for making Excel-DNA add-ins. Using VB.NET gives a degree of familiar syntax for those who are coming from VBA, requiring a gradual learning curve to get used to the few existing differences. However, rest assured that VB.NET provides access to the full power of .NET and Excel-DNA.
VB.NET 是 Visual Basic 家族的最新成员。尽管有时在受欢迎程度上被 C#所超越，但 VB.NET 与 C#一样强大（有时更强大），可以访问所有相同的.NET 库，并且完全支持制作 Excel-DNA 插件。使用 VB.NET 可以为那些来自 VBA 的人来说提供熟悉的语法，需要逐渐学习一些现有的差异。然而，请放心，VB.NET 提供了.NET 和 Excel-DNA 的全部功能。

Excel-DNA add-ins can also integrate with VBA code by creating custom COM libraries that can be called from VBA. One advantage in putting these libraries inside an Excel-DNA add-in is that they can be deployed without requiring registration with administrator privileges.
Excel-DNA 插件还可以通过创建可以在 VBA 中调用的自定义 COM 库来与 VBA 代码集成。将这些库放在 Excel-DNA 插件中的一个优点是，它们可以部署而无需管理员权限进行注册。
