Im working on the last portion of my code and I cant seem to write 7 items to a line. Right now my output has 10 items to a line. I am open to all suggestions.
I get 10 row and 10 columns, then a blank line followed by items that
are greater than 500 in my output.
Thanks so much. Code is below

C#

class ReadArray
    {
       
        static void Main()
        {
            int[] numberArray = new int[100];   //A 100 array element
            string number;                      //String input
            int item;                           //Array index
            
            int flag = 0;
            
            FileStream f = null;
            StreamReader s = null;
            try  
            {
                f = new FileStream("d:\\L01data.txt", FileMode.Open);
                s = new StreamReader(f);
            }
            catch 
            {
                Console.WriteLine("Does not exist");
                flag = 1; //set flag to indicate file failed to open
            }
            if (flag == 0) // File opened as expected
            {
                item = 0;
                while ((number = s.ReadLine()) != null)
                {
                    numberArray[item] = Convert.ToInt32(number);
                    item++;
                }
                for (item = 0; item < numberArray.Length; item++)
                {
                   Console.Write(numberArray[item]);
                   Console.Write('\t');
                }
                Console.WriteLine();
                //foreach loop to only write out the elements in numberArray
                //greater than 500
                foreach (int i in numberArray)
                {
                    if (i > 500)
                    {
                        Console.Write(i);
                    }
                    
                    Console.Write('\t');
                }
                
                s.Close();
                f.Close();
            }
}
}

Have a count variable outside of your last loop.
Inside the loop increment it. If it equals 7 then write Environment.NewLine and reset count, else write the tab

for (item = 0; item < numberArray.Length; item++)                {                   
  Console.Write(numberArray[item]);                   
  Console.Write('\t');                
}                
Console.WriteLine();

This section of code actually writes numberArray.Length items in one line and it is the automatic text wrapping of the console that just happens to give you 10 rows of 10 items. The tab width is 8 characters and when the console buffer width is the default 80 characters then wrapping will occur at every 10th tab.

What you should do is start a new line after every N items, where N is the desired number of columns.
