C# How do I load a .txt document into ListView after a button

Ok I'm trying to make a program so that when they click a button it will bring up a browser and have them locate the .txt document, and after they found it the information in the document will be sent into a listview grid if anyone can help me ASAP I would appreciate it a lot.

Sincerely,
rbhavocpzr

Simply invoke this method in the click event of a button:

        /// <summary>
        /// Loads the text into a list view.
        /// </summary>
        /// <param name="listView">The list view to load the text into.</param>
        private void LoadTextIntoListView(ListView listView)
        {
            // Ask the user to select a file
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Filter = "Text files (*.txt)|*.txt";
            if (openFileDialog.ShowDialog() == DialogResult.OK)
            {
                // Clear listview
                listView.Items.Clear();

                // Load text
                using (TextReader textReader = new StreamReader(openFileDialog.FileName))
                {
                    // Load the text line by line
                    string line = string.Empty;
                    while ((line = textReader.ReadLine()) != null)
                    {
                        // Append
                        listView.Items.Add(line);
                    }
                }
            }
        }

For example:

        private void button1_Click(object sender, EventArgs e)
        {
            LoadTextIntoListView(listView1);
        }

which listview?

If you mean the Windows Forms listview, post to the Windows Forms General forum

If you mean the WPF listview, post to the WPF forum

If you mean the asp.net listview, post to forums.asp.net
