File.WriteAllText("someFolder\semaphore.dat", "there is a new file called someFolder\myActualDataFile.txt");

using (StreamWriter swFromFile = new StreamWriter(logFileName)) {
    swFromFile.Write(textToAdd);
    ...
    swFromFile.Write(textToAdd);
} // file is closed properly by "using" which calls Dispose behind the scenes
