i am reading datas in text file and write into another text file..but getting exception ... FileStream fs=new FileStream("C:\\Vicky\\DATAS\\1.txt",FileMode.OpenOrCreate,FileAccess.Write); StreamWriter sw = new StreamWriter(fs); FileStream fs1 = new FileStream("c:\\one.txt", FileMode.Open, FileAccess.Read); StreamReader sr = new StreamReader(fs1); string[] s = new string[500]; for(int i = 0; i <= 500; i++) { s[i] = sr.ReadLine(); } for (int j = 0; j <= 500; j++) { sw.WriteLine(s[j]); } sw.Close(); sr.Close(); fs.Close(); fs1.Close(); error is: Index was outside the bounds of the array.in s[i]=sr.readline().....

An array is 0 based, so 500 elements are indexed from 0 to 499. Just get rid of the = in the for cycles :)

An array is 0 based. So if the array contains 500 elements the first has index 0 and the last 499. In your for cycle (with <=) at the end you were trying to access to the element with index 500 that obviously is outside the bounds of the array. http://msdn.microsoft.com/en-us/library/9b9dty7d(VS.80).aspx[^] :)
