How to get input from textbox in C#?

Question

First things first,I am very new to C# and programming all around. I have a standalone program that will read XML files in a certain location and convert them to plaintext files.

And I have a windows forms app that has a file directory and will display the chosen file in a textbox.

{
        Stream myStream;
        OpenFileDialog openFileDialog1 = new OpenFileDialog();
        if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            if ((myStream = openFileDialog1.OpenFile())!= null)
            {
                string strfilename = openFileDialog1.FileName;
                string filetext = File.ReadAllText(strfilename);
                textBox1.Text = filetext;
            }
        }
    }

Below is a snippet of my conversion program.

string[] files = Directory.GetFiles("C:\\articles");
        foreach (string file in files)
        {
            List<string> translatedLines = new List<string>();
            string[] lines = File.ReadAllLines(file);
            foreach(string line in lines)
            {
                if (line.Contains("\"check\""))
                {
                    string pattern = "<[^>]+>";
                    string replacement = " ";
                    Regex rgx = new Regex(pattern);
                    string result = rgx.Replace(line, replacement);
                    translatedLines.Add(result);
                }
            }

How would I modify my program to take the input from the textbox and then perform its conversion? (And Yes I'm aware I have to combine the two programs.)

You need to write the code of standalone program in to the windows app code. And change it to read only one file instead of all the files from a directory. — Chetan, Feb 19 '19 at 03:40
Yes I'm aware I have to move my program into the forms app, the question is how to specifically modify my code to get the input from the textbox. — Kirikaz, Feb 19 '19 at 06:33
When you move to form app add a textbox on it and suppose it have id as `textbox1` then in your code just do `textbox1.Text` and that will give you textbox value to you. You have to actually do it and try it then see if any issues happen. — Mahesh, Feb 19 '19 at 06:38
It seems you are reading an XML file by stripping off the `< >`. Know that there is for instance an XDocument class specifically designed to handle XML data. — Hans Keﬆing, Feb 19 '19 at 07:46
inside that conversion foreach you have code dealing with a single file. Move that to a separate method, with that "file" as parameter. Then copy that method to your filedialog application and call it with the result of that dialog — Hans Keﬆing, Feb 19 '19 at 10:00

Use XDocument class to parse the XML formatted string to XML Document so that you can get values on each Nodes of the XML

XDocument xDoc = new XDocument(); 
xDoc = XDocument.Parse(filetext);

Now read the content:

var textValue = xDoc.Descendants("Response").First().Attribute("Status").Value;

I know 100% im doing this wrong, can you tell me what exactly I got wrong? https://ibb.co/mqpXnKT – Kirikaz Feb 19 '19 at 20:16
the Descendants and Attribute value must exist on the XML file you're trying to read. refer to https://stackoverflow.com/questions/566167/query-an-xdocument-for-elements-by-name-at-any-depth – john carlo manuel Feb 20 '19 at 05:56
