如何获取 ClickOnce 创建的 Local App Data 文件夹中文件的路径

Question

I have a WPF project that I want to deploy via clickonce. I have a folder named "Data" with some files in it which will be created by clickonce in Local App Data folder when I install the application. I want to access those files but I am unable to figure out how to do that . The folder created by clickonce has some random name, it looks like this: "C:\\Users\\xxxxx\\AppData\\Local\\Apps\\2.0\\Data\\PG220ZY7.R26\\B0O5ZOCW.BX7\\oatr..tion_0000000000000000_0001.0000_73ac71b3d7a93fc2\\Data\\Data"

How can I access those files since I have no way to know what name the clickonce will assign to that folder? Thank you.

Check if application is network deployed if not will error. Then you can get the directory with ApplicationDeployment.CurrentDeployment.DataDirectory

Example from Microsoft

        if (ApplicationDeployment.IsNetworkDeployed)
        {
            try
            {
                using (StreamReader sr = new StreamReader(ApplicationDeployment.CurrentDeployment.DataDirectory + @"\CSV.txt"))
                {
                    MessageBox.Show(sr.ReadToEnd());
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Could not read file. Error message: " + ex.Message);
            }

        }
