找到VSTO Outlook Addin的安装目录和工作目录；或任何 Office 插件

问题描述

我创建了一个 VSTO Outlook 插件，它使用一个库 Html2Xhtml.dll (.NET)，它通过执行 System.Diagnostic.Process.Start() 调用另一个 Html2xhtml.exe.

I created a VSTO Outlook Addin that uses a library Html2Xhtml.dll (.NET) which calls another Html2xhtml.exe by executing System.Diagnostic.Process.Start().

但是，它无法调用 Html2xhtml.exe(我认为)，因为即使从 Visual Studio 启动，工作目录也是当前用户的我的文档"文件夹.我无法控制 Html2Xhtml.dll 中的代码，所以我不能使用绝对路径；但我想我可以在运行时更改加载项的工作目录.

However, it fails to call Html2xhtml.exe (i think) because the working directory even when launched from Visual Studio is the current user My Documents folder. I have no control over the code in Html2Xhtml.dll so I cannot use absolute path; but I suppose I can change the working directory of the Add-in at runtime.

但是，如果我通过 ClickOnce 或其他一些我不知道用户将选择的安装路径的方式安装它，我怎么能找到我的 Html2xhtml.exe?

However, If I install this via ClickOnce or some other means where I do not know the install path the user is going to choose, how am I suppose to find my Html2xhtml.exe?

I found the answer here, full credits to robindotnet.wordpress.com.

//Get the assembly information
System.Reflection.Assembly assemblyInfo = System.Reflection.Assembly.GetExecutingAssembly();

//Location is where the assembly is run from
string assemblyLocation = assemblyInfo.Location;

//CodeBase is the location of the ClickOnce deployment files
Uri uriCodeBase = new Uri(assemblyInfo.CodeBase);
string ClickOnceLocation = Path.GetDirectoryName(uriCodeBase.LocalPath.ToString());
