processing line breaks

Question

I'm creating a program in C# that goes through a string and calculate the frequency of characters in it.

Basically I have 2 class

    class Node
    {
       private char character;
       private float frequency;
       public void increment();//increments frequency
    }

    class FreqTbl
    {
        private List<Node> nodes;
        public void buildTable(char Symbol)
        {
            bool found = false;

       
            foreach (var node in nodes.Where(n => n.getSymbol() == Symbol))
            {
                node.increment();

                found = true;
            }

            if(found == false)
            {
                newNode(Symbol);
            }
        }
    }

Through a text box GUI, The program passes a char into FreqTbl.buildTable , which search through the nodes field. While all other characters are processed no problem, line breaks appears twice in the output

Say if the text box have the input

linked list

red black tree

The resultant output would be

l:3

i:2

n:1

k:2

e:4

d:2

:3

s:1

t:2

\n

:1

\n

:1

r:2

b:1

a:1

c:1

\n represents the line break. Anyway to fix this so that only 1 line breaks appear in the output?

Answer 1

Before passing each char into FreqTbl.buildTable you have option to process your input:

string strInput = textBox1.Text.TrimEnd('\r', '\n' );

Or

string strInput = textBox1.Text.TrimEnd(Environment.NewLine.ToCharArray());
