Namespace error OfficeOpenXML EPPlus
提问by user99999991
I'm having difficulty setting up EPPlus in Visual Studio 2012.
我在 Visual Studio 2012 中设置 EPPlus 有困难。
using OfficeOpenXML;
The type or namespace name 'OfficeOpenXML' could not be found(are you missing a using directive or an assembly reference?)
Now I tried 2 different ways to set EPPlus up.
现在我尝试了 2 种不同的方法来设置 EPPlus。
I manually added a Project->Add Reference to the Epplus.dll file in my documents.
我在我的文档中手动添加了一个 Project->Add Reference 到 Epplus.dll 文件。
I also tried to use NuGet package manager console: PM> Install-Package EPPlus
我还尝试使用 NuGet 包管理器控制台：PM> Install-Package EPPlus
I clearly see EPPlus is added to the References in my project, but the namespace for OfficeOpenXML is not added. How do I add this namespace with the EPPlus reference?
我清楚地看到 EPPlus 已添加到我的项目中的 References，但未添加 OfficeOpenXML 的命名空间。如何使用 EPPlus 引用添加此命名空间？

I believe this is just a problem of casing. This:
我相信这只是外壳的问题。这个：
using OfficeOpenXML;
should be:
应该：
using OfficeOpenXml;
Note the lower case "M" and "L" at the end.
注意末尾的小写“M”和“L”。
I say that based only on the sample code...
我说的是仅基于示例代码......

就我而言，我还在 Visual Studio 2012 中使用了 EPPlus，该项目是从 vs2005 升级的。在 Framework2.0 中。如果我将项目更改为 .Net framework 4.5，则重建成功。

I had the same issue, check that your project's Target Framework (Right click on your project -> Properties, check "Target framework") is not set to any .NET framework X "Client Profile" frameworks. Client profile is a minified version of whatever framework you are using.
我遇到了同样的问题，请检查您项目的目标框架（右键单击您的项目 -> 属性，检查“目标框架”）是否未设置为任何 .NET 框架 X“客户端配置文件”框架。客户端配置文件是您使用的任何框架的缩小版本。
With regards to EPPlus, your project must be using the full framework and not any "Client Profile" frameworks
关于 EPPlus，您的项目必须使用完整的框架，而不是任何“客户端配置文件”框架

I had only installed DocumentFormat.OpenXmland the reference would not work despite following other sources on the net.
我只安装了DocumentFormat.OpenXml，尽管遵循网络上的其他来源，但参考不起作用。
I had to install, through NuGet, both DocumentFormat.OpenXmlAND EPPlusto get the reference to work.
我必须通过 NuGet 安装DocumentFormat.OpenXmlANDEPPlus才能使参考工作。
That fixed this for me.
那为我解决了这个问题。
