在 Wix 安装期间，C# 自定义操作无法找到 appsettings.json 文件
C# Custom Action not able to locate appsettings.json file during Wix install
我为我的网络应用程序创建了一个 Wix 安装程序，但在尝试替换我的 appsettings.json 文件中的值时 运行 遇到了问题（使用我从用户那里获得的信息我创建的自定义对话框）。信息从我的对话框完美地传递到我的自定义操作。然后它失败并抛出错误。下面，我将 post 我得到的错误，安装程序项目的 .wixproj 文件，安装程序项目中的 Produxt.wxs 文件，最重要的是 CustomAction class 来自我的自定义动作项目。问题是我不知道如何在安装过程中以编程方式识别 appsettings.json 文件的正确文件路径。我很迷茫，真的需要一些帮助...谢谢。
错误（在 CustomActions.cs 中的 AddOrUpdateAppSetting 方法的第二行抛出）
ex = {"Could not find file 'C:\Users\DeanFriedland\AppData\Local\Temp\MSI8E19.tmp-\appSettings.json'.":"C:\Users\DeanFriedland\AppData\Local\Temp\MSI8E19.tmp-\appSettings.json"}

答案是让我从这样的安装文件夹中找到路径：
var filePaths = Directory.GetFiles(@"c:\Program Files (x86)\OpenBotServer\", "*.json");
