The Windows Forms TextBox control has a SelectedText property which will return the selected portion of the TextBox's value.

Answer 2

From MSDN's Code: Determining the Selected Text in a TextBox Control (Visual C#)

private void button1_Click(object sender, System.EventArgs e)
{
    textBox1.Text = "Hello World";
    textBox1.Select(6, 5);
    MessageBox.Show(textBox1.SelectedText);
}

Answer 3

TextBox has a SelectedText property which will return whatever text is selected in the box.

Answer 4

Windows Forms TextBox doesn't have a SelectionChanged event, although the RichTextBox control does. You could use a variety of hacks such as a timer, handling mouse up and key up events to trigger your selection change logic. Then use the SelectedText as others have suggested.
