what is best way to sort lines in RichTextBox

Question

I'm looking for the best way to sort lines of RichTextBox, I'm using this at moment:

public void SortLines(object sender, EventArgs e)
{
    TextPointer pStart = TextInput.Document.ContentStart;
    TextPointer pEnd = TextInput.Document.ContentEnd;
    TextRange text = new TextRange(pStart, pEnd);

    string[] lines = text.Text.Split('\n');
    Array.Sort(lines);
    text.Text = String.Join(String.Empty, lines);
}

1. Is there an best way to do this?

2. When I call it, the cursor is placed into first RichTextBox line, how do I to put it where it was before? I tried to set pStart/pEnd and CaretPositiom, but the properties are read only.

I hope this is clear. Thanks in advance.

An inelegant but practical solution; back and forth richtextbox to ListBox : In the properties on your listBox you click 'sorted'> true

[c#]

ListBox1.Items.AddRange(RichTextBox1.Lines);
for (int x = 0; (x 
            <= (ListBox1.Items.Count - 1)); x++) {
    RichTextBox1.AppendText((ListBox1.Items(x).ToString.Environment.NewLine));
}

[VB.NET]

ListBox1.Items.AddRange(RichTextBox1.Lines)
For x As Integer = 0 To ListBox1.Items.Count - 1
RichTextBox1.AppendText(ListBox1.Items(x).ToString & Environment.NewLine)
