How do I find three or more substrings within a string and process them.

"The best time to start is now. Some time gen-\r\n
erally means no time. You can put away as much as I put away, if you try."\r\n
" All right, I’ll do it—next week."\r\n
" No, this week," and Dale smiled good-hu-\r\n
moredly.\r\n
"Gracious, Dale! are you becoming my guar-\r\n
dian.\r\n

In the string above I need to find the gen-\r\n, and move up the rest of the word erally to join them together to make gen-erally. Same with good-hu- and guar- I can use the substring of -\r\n to find them but I cannot find a way to go past the first substring.

What I have tried:

I need a find next or something. I have searched Google for a way to do it but have not found what I am looking for. I seem to remember seeing something before but cannot think of it or find it now. I have tried using

while (SaveWordIndex != -1);

but that will not work, it is never -1.

Sorry, here is my code if it helps.

foreach (KeyValuePair<string, string> record in MyOCR.ToList())
            {
                string v1 = record.Key;
                string v2 = record.Value;


                pageString = v2;
                SaveWordIndex = pageString.IndexOf("-" + "\r\n");
                if (SaveWordIndex != -1)
                {
                    SaveWords1 = pageString.Substring(0, SaveWordIndex);
                    pageString = pageString.Remove(0, SaveWords1.Length);
                    SaveWordIndex = pageString.IndexOf(" ");
                    if (SaveWordIndex != -1)
                    {
                        SaveWords2 = pageString.Substring(0, SaveWordIndex);
                        SaveWords2 = SaveWords2.Remove(0, 3);  // remove the -\r\n
                        SaveWords3 = SaveWords1 + SaveWords2 + CrLf;
                        pageString = pageString.Remove(0, SaveWordIndex + 1);

                        richTextBox1.Text = SaveWords3 + pageString;
                    }
                }

Use a Regular Expression.

Wish I knew Regx, perhaps now is the time to start learning it.

Use the String.IndexOf Method (System) | Microsoft Learn[^], which allows you to specify the starting position to seach from. You could also use String.Split Method (System) | Microsoft Learn[^] to separate into an array of strings delineated by the "-\r\n". You then recombine the resultant strings to get the results you want.

[edit]
You could also use the String.Replace Method (System) | Microsoft Learn[^].

Looks like I will have to use the split method to make this work. I was hoping to avoid that way of doing this, so messy.

You could just use string.Replace:

C#

string str = "\"The best time to start is now. Some time gen-\r\n"
            +"erally means no time. You can put away as much as I put away, if you try.\"\r\n"
            +"\" All right, I’ll do it—next week.\"\r\n"
            +"\" No, this week,\" and Dale smiled good-hu-\r\n"
            +"moredly.\r\n"
            +"\"Gracious, Dale! are you becoming my guar-\r\n"
            +"dian.\"\r\n";
str = str.Replace("-\r\n", "-");
Console.WriteLine(str);

"The best time to start is now. Some time gen-erally means no time. You can put away as much as I put away, if you try."
" All right, I’ll do it—next week."
" No, this week," and Dale smiled good-hu-moredly.
"Gracious, Dale! are you becoming my guar-dian."
