C＃自定义操作无法在Wix安装过程中找到appsettings.json文件

如何解决C＃自定义操作无法在Wix安装过程中找到appsettings.json文件

我为我的Web应用程序创建了一个Wix安装程序，并且尝试替换appsettings.json文件中的值时遇到了问题（在我创建的自定义对话框中，该信息是从用户那里获得的）。信息已从我的对话框完美传递到我的自定义操作。然后它失败并引发错误。下面，我将发布错误，安装程序项目的.wixproj文件，安装程序项目中的Produxt.wxs文件，最重要的是我的自定义项中的CustomAction类行动项目。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，真的可以使用一些帮助...谢谢。

错误（在CustomActions.cs中的AddOrUpdateAppSetting方法的第二行上引发）

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"}

解决方法

答案是我可以从安装文件夹中找到路径，如下所示：

var filePaths = Directory.GetFiles(@"c:\Program Files (x86)\OpenBotServer\","*.json");
