How to use two types of fonts in a richtextdocument

Question

hello,
       i want to print a barcode and some text into  a richtextdocument
example:
this.richTextBox1.AppendText("\n");
Font f1 = new Font("3 of 9 Barcode", 50);
this.richTextBox1.Font = f1;
this.richTextBox1.AppendText("*1234554*");
Font f2 = new Font("Arial", 20);
this.richTextBox1.Font = f2;
this.richTextBox1.AppendText("fooo");
but it always uses the second one?
how can i resolve this?
i want to use two types of fonts in the same rich text document.

Select some text and then set the SelectionFont property for each selection, e.g.:
this.richTextBox1.AppendText("\n");
this.richTextBox1.AppendText("*1234554*");
richTextBox1.SelectionStart = 1;
richTextBox1.SelectionLength = 9; //End of first word
richTextBox1.SelectionFont = new System.Drawing.Font("Tahoma", 10);
this.richTextBox1.AppendText("fooo");
richTextBox1.SelectionStart = 10;
richTextBox1.SelectionLength = 4;
richTextBox1.SelectionFont = new System.Drawing.Font("Arial", 20);
