The All Method checks for all the values in a collection and returns a Boolean. Even if one of the element do not satisfy the set condition, the All() method returns False.Let us see an example −int[] arr = {10, 15, 20};Now, using All() method, we will check whether each ... Read More

Firstly, set a string.StringBuilder str = new StringBuilder();Use Random.Random random = new Random((int)DateTime.Now.Ticks);Now loop through a number which is the length of the random string you want.for (int i = 0; i < 4; i++) {    c = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65)));    str.Append(c); }On every iteration above, ...
