public static void Main(string[] args)
{
Random res = new Random();
String str = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
String randomstring = "";
for (int i = 0; i < 1000; i++){
for (int a = 0; a < 7; a++)
{
int x = res.Next(str.Length);
randomstring = randomstring + str[x];
}
string file = @"codes.txt";
File.WriteAllText(file, $"{randomstring}\n");
Console.WriteLine("Random alphanumeric String:" + randomstring);
