Taking Array input from a TextBox

Question

I just had a question. I want to let the user enter a number of characters/numbers in a TextBox separated by commas and then the code to read it in a way so that each element in the TextBox separated by the comma is a separate element in an array into which I want to input those characters/numbers.
For example: Input: 12, good, 5
Elements in the array:{12, "good", 5};

I hope everyone understood my question and will be able to help me.
Thanks.

Solution 2

Easy:

C#

string s = "12,good,5";
string[] parts = s.Split(',');

If you also need to remove spaces:

C#

string s = "12, good, 5";
string[] parts = s.Split(',').Select(p => p.Trim()).ToArray();

What is the meaning of "=>" over here? and what is p?
I'm a beginner programmer so sorry for these questions.

It's what's called a "lambda expression" and you will meet them later on in your course.
For the moment, ignore them, and do it this way:
string[] parts = s.Split(',');
for (int i = 0; i < parts.Length; i++)
{
parts[i] = parts[i].Trim();
}
You'll understand what I'm doing when you get to Linq, but I don't want to confuse you by explaining something you aren't ready for yet, and won't meet for weeks!
Just think of it as a "shorthand" for the loop (it isn't, but it'll do as an explanation for the moment)
