How to save richboxtext content to .txt file via saveFiledialog?

I'm trying to create a simple notepad for my self. At the moment i have created a button where i can Open file and get content. How can i create a Save file button so every line of my richboxtext goes to new .txt file?

I want that i can save to a file name of my choice not a static one so i use SaveFileDialog.

This is what i have for Open File.

if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
    Stream plusma = openFileDialog1.OpenFile();

    string faila_nosaukums = openFileDialog1.FileName;
    string faila_teksts = File.ReadAllText(faila_nosaukums);
    rtf_NotePad.Text = faila_teksts;
}

Nothing up for Save file at the moment: 

if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{

}

----------Updated-----------------
Saving file:

            saveFileDialog1.Filter = "Text Files (*.txt)|*.txt|RTF Files (*.rtf)|*.rtf";
            saveFileDialog1.AddExtension = true;

            if (saveFileDialog1.ShowDialog() == DialogResult.OK)
            {
                rtf_NotePad.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText);
            }

Adding color:

            colorDialog1.ShowDialog();
            rtf_NotePad.ForeColor = colorDialog1.Color;

You can use SaveFile(String, RichTextBoxStreamType) method of your rich text box and and pass RichTextBoxStreamType.PlainText as second parameter.

Also if you want to let the user choose to save in .txt format or .rtf:

var saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Text Files (*.txt)|*.txt|RTF Files (*.rtf)|*.rtf";
saveFileDialog.AddExtension = true;
if (saveFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    var extension = System.IO.Path.GetExtension(saveFileDialog.FileName);
    if(extension.ToLower()==".txt") /*saveFileDialog.FilterIndex==1*/
        richTextBox1.SaveFile(saveFileDialog.FileName, RichTextBoxStreamType.PlainText);
    else
        richTextBox1.SaveFile(saveFileDialog.FileName, RichTextBoxStreamType.RichText);
}

You should know .rft format is different from .txt format. If you save in .rtf format, the formatting including font and color remains, but if you save in .txt format, it only saves the plain text. And if you want to simulate notepad, you don't need to use .rtf format.

Another point is if you want to have only the Font option like notepad, the font option would be a User Settings that can be saved via Settings.settings. Then you can set that font for your TextBox/RichTextBox after application loads. This way you can save the file in .txt format.

You can use the RichTextBox.SaveFile() method:

if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
    rtf_NotePad.SaveFile(saveFileDialog1.FileName);
}

Also, there exists a similar method for opening the file. It is the RichTextBox.LoadFile() method. Use it like this:

if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
    rtf_NotePad.LoadFile(openFileDialog1.FileName);
}
