✅ Random character generator

Hello, as a beginner, I am currently working on making a simple lottery simulator. However, I didn't know how to generate a sequence of 8 letters and numbers. Naturally, I searched it up and I got the answer. But copying chunks of code wouldn't help me learn and I can't seem to wrap my head around how this works. I understand the variables, but I can't just seem to understand what the variable i does and why i = 0. Would anyone be kind enough to explain the for statement and what each argument does. Thank you so much 🙏

var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
            var stringChars = new char[8];
            var randomNumber = new Random();

            for (int i = 0; i < stringChars.Length; i++)
            {
                stringChars[i] = chars[randomNumber.Next(chars.Length)] ;
            }

            var finalString = new String(stringChars);

            Console.WriteLine(finalString);

var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
            var stringChars = new char[8];
            var randomNumber = new Random();

            for (int i = 0; i < stringChars.Length; i++)
            {
                stringChars[i] = chars[randomNumber.Next(chars.Length)] ;
            }

            var finalString = new String(stringChars);

            Console.WriteLine(finalString);

After messing around with the values and variables I now know what i means and how the loop works. However, another problem came to mind. Is there a way to return to a previous line of code? for example when I press something like space, it returns to before the sequence is generated and it would give me another code without having to restart the entire program

Search up these keywords: Goto, return, continue, break Although using goto isn't considered proffessional
