How can i copy text to a richbox from a text file?

I want to copy the text from a .txt file into a richbox when the form loads. I don't want to open a dialog to choose the file, just open a specific file automatically

 Stream sr;
        OpenFileDialog openFileDialog1 = new OpenFileDialog();
        if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            if ((sr = openFileDialog1.OpenFile()) != null)
            {
                string strfilename = openFileDialog1.FileName;
                string commandstext = File.ReadAllText(strfilename);
                richTextBox2.Text=commandstext;
            }
        }

        using (StreamReader sr = new StreamReader("YourFilePath.txt"))
        {
            String line = sr.ReadToEnd();
            richTextBox2.Text=line;
        }

You can also do as suggested in other 2 answers.

OR other faster way as:

void LoadFileToRTB(string fileName, RichTextBox rtb)
{
  rtb.LoadFile(File.OpenRead(fileName), RichTextBoxStreamType.PlainText); // second parameter you can change to fit for you
  // or
  rtb.LoadFile(fileName);
  // or
  rtb.LoadFile(fileName, RichTextBoxStreamType.PlainText); // second parameter you can change to fit for you
}

    Stream sr;
    string strfilename = "PATH TO FILE"; //Code should know the path already
    string commandstext = File.ReadAllText(strfilename);
    richTextBox2.Text=commandstext;
