My psychic debugging skills tell me that your function is an iterator function, meaning that it contains yield return; statements. Code in iterator functions is only executed as the result is iterated. This is called deferred execution. 4 solved Why my code did not get into my function [closed]
Here are three versions of your code to demonstrate what is going on, and what I think you’re really asking: Original: private void button1_Click(object sender, EventArgs e) { // Set c to 100 int c=100; // Print the result of Count, which (see below) is ALWAYS 115.

You can loop through the array to get the maximum value and you only need to retain the largest value found thus far, so: int max = Int32.MinValue; for (var i = 0; i < array.Length; i++) { if (array[i] > max) { max = array[i]; } } Console.WriteLine(max); You can also use .Max() and … Read more
