C# dasturlash tilida massivlar bilan ishlash

5- misol. fayldan ma’lumotlarni satrma - satr o’qish.
class Program
{ static void Main(string[] args)
{
FileStream a = new FileStream("d:\\textFile.txt", FileMode.Open,
FileAccess.Read);
StreamReader b = new StreamReader(a);
string s; while ((s = b.ReadLine()) != null){ Console.WriteLine(s); }
b.Close();
Console.ReadKey();
} }
6- misol. a.txt fayldagi barcha sonlarni yig’indisini b.txt faylda chiqarish. class Program
{ static void Main(string[] args)
{
StreamWriter yozish = new StreamWriter("d:\\a.txt"); StreamReader uqish = new StreamReader("d:\\b.txt"); int b, n, k,s=0; string a; while ((a = (uqish.ReadLine())) != null)
{ s = s + int.Parse(a);
} yozish.WriteLine(s+""); yozish.Close();
Console.ReadKey();
} }
7- misol. a.txt fayldagi eng uzun so’zni b.txt faylda chiqarish.
class Program
{ static void Main(string[] args)
{
StreamWriter yozish = new StreamWriter("d:\\a.txt"); StreamReader uqish = new StreamReader("d:\\b.txt"); int b, n, k,s=0; string a,x,y; k:=0; x:= ""; while ((a = (uqish.ReadLine())) != null) {if (a.length()>k) {x = a; k=a.length();}} yozish.WriteLine(x); yozish.Close();
Console.ReadKey();
} }
