Iam splitting words in richtextbox with space as delimeter
and each word has rtf
am saving word text and word rtf in database and retrieving and showing in datagridview

But problem is some word rtfs changed from actual rtf
so am not getting actual words

My code is

string[] parsList = rtxtPAR.Text.Split(new string[] {"\n" }, StringSplitOptions.RemoveEmptyEntries);
LstNewPAR = new List<string>(parsList);

XML

private List<string> GenerateRtfForList()
        {

            LstNewPAR_Rtf = new List<string>();
            string[] splitter = { "\n" };
            char[] delim = { '\n' };
            //string[] LstNewPAR = rtxtPAR.Text.Split(splitter, StringSplitOptions.RemoveEmptyEntries);
            var lstNewParText = rtxtPAR.Text.Split(delim, StringSplitOptions.RemoveEmptyEntries);
            for (int i = 0; i < LstNewPAR.Count(); i++)
            {

                rtxtPAR.Text = lstNewParText[i];

                HilightRichTextBoxText();
                LstNewPAR_Rtf.Add(rtxtPAR.Rtf);
            }



            return LstNewPAR_Rtf;

        }

any suggestions

Your code does not show you splitting the RTF-Text by words: it only shows splitting by lines.

"word rtfs changed from actual rtf" ... please give specific examples

What is the final result you want ?

One big Array or List<string> of all the words ?

An Array of Arrays ? A List<List<string>> ?

Assuming you want to convert the Text in a RichTextBox to a List<List<string>>, where each element of the List will be a List<string> containing one line of the RichTextBox parsed into words:

C#

// define in Form scope
private char[] splitLines = new char[] { '\n' };
private char[] splitWords = new char[] { ' ' };

// RichTextBox => List<List<string>>;
private List<List<string>> ParseRichTextBox(RichTextBox rtfBox)
{
    List<string> rtfLineList = new List<string>(rtfBox.Text.Split(splitLines, StringSplitOptions.RemoveEmptyEntries));

    List<List<string>> rtfLineWordList = new List<List<string>>
    (
        rtfLineList.ConvertAll<List<string>>
        (
            (string s) => 
            { 
                return new List<string>
                    (s.Split(splitWords, StringSplitOptions.RemoveEmptyEntries));
            }
        )
    );

    return rtfLineWordList;
}

Test:

// assume a RichTextBox named 'richTextBox1 on a Form
List<List<string>> parsedRtf = ParseRichTextBox(richTextBox1);

Notes:

1. formatting is deliberately very "spread out" here, to, hopefully, make the structure clearer. you could re-write this in a much terser form.

2. the form of the Linq 'ConvertAll method used here requires C# 3.0 or later.

3. I've been looking for an excuse to use 'ConvertAll :)
