try this code:

int yIndex = 0;
using (var fileStream = File.OpenRead("t.txt")) //t.txt your input file
using (var streamReader = new StreamReader(fileStream, Encoding.UTF8, true))
{                
     String line;
//read line by line and yIndex is added each time
     while ((line = streamReader.ReadLine()) != null)
     {
        for(int i=0; i< line.Length;i  )
             if(line[i]== 'O')
             {
                 Console.WriteLine("X is: {0}    Y is:{1}",i.ToString(),yIndex);
             }
                yIndex  ;
    }
}

result:

X is: 4 Y is:7

            int counter = 0;
            int inlinecounter = 0;
            string line;

            var text = "O";

            System.IO.StreamReader file =
                new System.IO.StreamReader("TextFile1.txt");

            while ((line = file.ReadLine()) != null)
            {
                if (line.Contains(text))
                {
                    inlinecounter = line.IndexOf(text, 0);
                    break;
                }

                counter  ;
            }

            Console.WriteLine("Line number: {0}", counter);
            Console.WriteLine("inLine number: {0}", inlinecounter);

Is that the only 'O' in that file?
If so you should do the following:
have a counter Y - that will represent how many lines you iterated through. This counter will start at zero and will never be reset.
have a counter X - that will represent how many characters you iterated through in the current line. This counter will start at zero and will reset in every new line.

Flow:

int x = 0
int y = 0
for line in lines
   x = 0
   for character  in line
       if character == 'O'
         print(x,y)
       x  
   y
