[RESOLVED] Working with strings

My application has a textbox in which the user enters "names". I per line.

I wrote some code to get the total count of the "names" and discovered it worked properly.

However if the user accidentally presses enter again after typing in the names it will get an in accurate count because it is counting the enter spaces as a line.

-Is there a way to remove any extra enter spaces at the end of my code
so the count wont be messed up?

-Example?

Thanks

When you count lines, don't just count enters.
First, get string from textbox. Then split it by enter. the length of string array would be the number of lines.

Code:

---

            string str = richTextBox1.Text;
            string[] strs = str.Split(new string[] { "\n" }, StringSplitOptions.RemoveEmptyEntries);
            int countOfLines = strs.Length;

That won't work because the enter spaces are counted as "\n" and using "StringSplitOptions.RemoveEmptyEntries" wont remove the extra enterspaces because it sees them as "\n" and won't remove them up to the current text.

Did you try this?

If it doesn't work, please post the source code you are using, let's see why.

Here you go.

Code:

---

        public int GetNamesCount( )
        {
            string[ ] names = NamesForm.txtNames.Text.Split( new String[ ] { "\n" }, StringSplitOptions.RemoveEmptyEntries );
           
            int Count = 0;
            foreach( string name in names )
            {
                Count++;
            }
            if( NamesForm.txtNames.Text.Length == 0 )
            {
                return 0;
            }
            else
            {
                return Count;
            }
        }

I don't know if you use RichTextBox control or not. I typed lots of lines and lots of enters in RichTextBox. It did work.

In your function, just return length of array "names".

Did you type "\n" instead of Enter?

I'm totally confused.

I will agree with Jason here. I tested it, and it worked with a RichTextBox. However, it did NOT work with a textbox with the "multiline" property set to true.

Pale, are you sure you are using a RichTextBox?

EDITED: you answered before I could post.

If you want to use a textbox instead of a richtextbox, use "\r\n" instead of "\n"

Code:

---

        public int GetNamesCount( )
        {
            string[ ] names = NamesForm.txtNames.Text.Split( new String[ ] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries );
           
            int Count = 0;
            foreach( string name in names )
            {
                Count++;
            }
            if( NamesForm.txtNames.Text.Length == 0 )
            {
                return 0;
            }
            else
            {
                return Count;
            }
        }

Of course the real fix would be to split on 'Environment.NewLine'
