问题

I am currently trying to deploy an Outlook VSTO Add In that I developed with Visual Studio. As long as I debug it with Visual Studio everything works perfectly fine. However, I ran into sume trouble as soon as I deployed it and installed it via the created .exe installer.

我目前正尝试部署我用Visual Studio开发的Outlook VSTO插件。只要我在Visual Studio中调试它，一切都运行得非常完美。但是，一旦我部署它并通过创建的.exe安装程序安装它，我就遇到了一些问题。

I pinned down the problem and it seems to be an additional .json file that the Add In opens and reads on start up. I created this file and store it in my Visual Studio Project Directory to save some data that the Add In needs.

我锁定了问题，似乎是插件在启动时打开并读取的一个额外的.json文件。我创建了这个文件并将其存储在我的Visual Studio项目目录中，以保存插件所需的一些数据。

I figured that the deployed and installed Add In might have difficulties finding the file as there might be a new filepath. So I tried the following:

我想到，已部署和安装的插件可能难以找到该文件，因为可能存在新的文件路径。所以我尝试了以下方法：

1. In the file properties set in Visual Studio I changed the settings to always copy the file to the output directory and build its content

2. 在Visual Studio中设置的文件属性中，我更改了设置，始终将文件复制到输出目录并构建其内容

3. I changed the filepath from which the file is opened from just "file.json" to Dim jsonFilePath As String = System.AppDomain.CurrentDomain.BaseDirectory + "file.json"

4. 我将打开文件的文件路径从"file.json"更改为Dim jsonFilePath As String = System.AppDomain.CurrentDomain.BaseDirectory + "file.json"

Both approaches did not work. So my question is if anyone has ideas on how I could fix that.

这两种方法都没有奏效。所以我的问题是，是否有人有想法如何修复这个问题。

Many thanks in advance!

提前感谢您！

Update: Due to your ansers I figured it out. In VB.Net I now use:

更新：由于您的回答，我已经弄清楚了。在VB.Net中，我现在使用以下代码：

Dim codebase As New System.Uri(Assembly.GetExecutingAssembly().CodeBase)
Dim filepath As String = Path.Combine(codebase.AbsolutePath, "..", "file.json")

Dim codebase As New System.Uri(Assembly.GetExecutingAssembly().CodeBase)
Dim filepath As String = Path.Combine(codebase.AbsolutePath, "..", "file.json")

你可能遇到了影子拷贝的问题。请使用 Assembly.GetExecutingAssembly().CodeBase 替代：

string codebase = Assembly.GetExecutingAssembly().CodeBase;
var vUri = new UriBuilder(codebase);
string vPath = Uri.UnescapeDataString(vUri.Path + vUri.Fragment);
string directory = Path.GetDirectoryName(vPath);
if (!string.IsNullOrEmpty(vUri.Host)) directory = @"\\" + vUri.Host + directory;
string jsonFilePath = Path.Combine(directory, "file.json");

string codebase = Assembly.GetExecutingAssembly().CodeBase;
var vUri = new UriBuilder(codebase);
string vPath = Uri.UnescapeDataString(vUri.Path + vUri.Fragment);
string directory = Path.GetDirectoryName(vPath);
if (!string.IsNullOrEmpty(vUri.Host)) directory = @"\\" + vUri.Host + directory;
string jsonFilePath = Path.Combine(directory, "file.json");

以下是翻译好的部分：

这是在运行时处理程序集路径/位置时广泛存在的问题。 您可以使用以下代码在运行时获取程序集位置：

string path = (new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath;

有关更多信息，请参阅获取当前程序集的路径。

另外，作为可能的解决方法，您可以考虑在插件安装时将安装目录路径添加到Windows注册表中（通过MSI安装程序中的自定义操作）。 因此，随时都可以读取该路径并处理本地文件，而无需依赖于程序集路径。

string path = (new System.Uri(Assembly.GetExecutingAssembly().CodeBase)).AbsolutePath;
