Unable to write text to a .txt file

I have a Windows forms application, that is supposed to store its config data on a file called config.txt. I have this code, which runs when the form is initialized. Here is the function:

config.txt

string folderPath = @‘C:UsersPublicPeriodic_Clock’;
string filePath = @‘C:UsersPublicPeriodic_Clockconfig.txt’;

public Form1()
{

InitializeComponent();
once = 0;
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}

if (!File.Exists(filePath))
{
new FileStream(filePath, FileMode.Create, FileAccess.ReadWrite);
File.WriteAllText(filePath, "Alarm" + Environment.NewLine + "Alarm Ringing!" + Environment.NewLine + 1);
}
else
{

}
notificationTitle = File.ReadLines(filePath).Skip(0).Take(1).First();
notificationText = File.ReadLines(filePath).Skip(1).Take(1).First();
}


Pretty much, I have an app that sends a notification when a timer goes off. I want to use this config file to store a custom title, text and notification type for the notification. (so that the user can customize what the notification looks like) My intention with this was to have the first line as the notification title, second line as the text, and the third line as a number from 0 - 3, to store the type of notification (info, error, etc.)

I can not manage to get the program to write anything to the text file. It creates it, but it seems to completely skip the part where I use File.WriteAllText(). I used other methods like StreamWriter, but nothing was written to the text document. The code right now skips the WriteAllText part and creates an error at File.ReadLines, which just tells me that the sequence contains no elements. What's the problem here? How do I fix it?

File.WriteAllText()

StreamWriter

WriteAllText

File.ReadLines

new FileStream

WriteAllText

In the end, I ended up with this code:

public Form1()
{
InitializeComponent();
once = 0;
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}
try
{
FileStream config = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.ReadWrite);
config.Close();
StreamWriter writetext = new StreamWriter(filePath);
writetext.Write("Alarm");
writetext.WriteLine();
writetext.Write("Alarm Ringing!");
writetext.WriteLine();
writetext.Write("1");
writetext.Close();

}
catch(Exception ex)
{
MessageBox.Show(ex.Message, "Error!");
}
notificationTitle = File.ReadLines(filePath).Skip(0).Take(1).First();
notificationText = File.ReadLines(filePath).Skip(1).Take(1).First();
}

In this case, the file is created, but not the content, so my answer doesn't apply. I'll leave it here despite the negative votes, because it may be the solution for others experiencing similar problems.

You need administrator rights to write to the default user profile. You can request them by adding requestedexecutionlevel to the manifest.

Also, do all the other stuff others recommend. A better structured program with better error handling helps you diagnose problems like this faster.
