Whether or not you need an array depends on what you need to do with the data. You don't need an array to read the data but you might need an array to process the data.

Will there always be one and only one colon in the first position? If so then you can use the String.Substring Method to get the data excluding the colon. Then you can use the String.Split Method to split the numbers that are separated by a space. Then use the Int32.TryParse Method to convert the characters to integers.

Sam thanx. my data is integer. format :4 20 2003 (month day year)
does it mean i don't need array to read all the 10 lines of my data file?

I don't know the format of your data but the following will read a file and parse the records into a DateTime object.

class Program

{

	static void Main(string[] args)

	{

		String Record;

		DateTime mydate;

		using (StreamReader textReader = new StreamReader("..\\..\\Date.txt"))

		{

			while (!textReader.EndOfStream)

			{

				Record = textReader.ReadLine();

				if (DateTime.TryParse(Record, out mydate))

					Console.WriteLine(mydate);

				else

					Console.WriteLine("Parse error for: {0}", Record);

			}

		}

	}

}
