Question:

How to solve the system StackOverflow Exception?

Solution:

Please verify that your code has no proper base case (exit condition) and is recursive. You are limited to a certain depth of recursion.

All you need to do is create a string that begins with TEK and has, in your case, 15 digits added to it.

The following creates a string containing 15 random digits:

public string CreateRandomCode(int codeCount = 15)

{

string allChar = "0,1,2,3,4,5,6,7,8,9";

string[] allCharArray = allChar.Split(',');

string randomCode = "";

Random rand = new Random();

for (int i = 0; i < codeCount; i++)

{

randomCode += allCharArray[rand.Next(0, allCharArray.Length)];

}

return randomCode;

}
