获取位置路径 Wix 安装

如果我想访问 mylocation.txt 文件，如何获取位置路径，该文件当前在 E:drive 中.

How to get location path if i want to access mylocation.txt file, this file currently is in E:drive.

[CustomAction]
    public static ActionResult FillList(Session xiSession)
    {

    //Can i get store mylocation.txt into application root instead of E location
        string path = "Mylocation.txt";

        // Open the file to read from. 
        string[] readText = File.ReadAllLines(path);

        foreach (string s in readText)
        {
            //Console.WriteLine(s);
            FillComboBox(xiSession, s, s);
        }
         xiSession["COUNTRIES"] = "--Select Location--";
        return ActionResult.Success;
    }

我可以将 mylocation.txt 存储到应用程序根目录而不是 E location.And 如何调用 mylocation.txt 吗?基本上我想要的是从这个文本文件中获取 combox 的值，一旦安装正在进行.

Can i get store mylocation.txt into application root instead of E location.And how mylocation.txt can be called?Basically what i want is to get the values of combox from this text file,once installation is in progress.
