You have to do the following to get the saved Counter :
1.1. Open the File
1.2. Read your Value
1.3. Close the File

And you have to do the following to save the Counter :
2.1. Open the File
2.2. Write your Value
2.3. Close the File

private static int _count;
private static readonly string _fileName = @"C:\my\file\path\and.name";
private static readonly Object _sync = new Object();

public static void Increment()
{
   lock(_sync)
   {
      _count++;

      File.WriteAllText(_fileName, _count.ToString());
   }         
}

void AppStartEvent()
{
   lock(_sync)
   {
      var seed = File.ReadAllText(_fileName);
      int result = 0;
      if(int.TryParse(seed,out result))
      {      
         _count = result;
      }else{
         _count = 0;
      }
   }
