IndexOutofRangeException Winform

Question

What's wrong with my code??

  string birthdate = ((DataRowView)comboBox1.SelectedItem).Row["birthdate"].ToString(); //pulled the data into the database ()

string[] split = birthdate.Split('/'); //split the Date

I want to put them in a textbox so I thought of doing this:

textbox1.Text = split[0]; //correct, gets the 1st word the (Day)
    textbox2.Text = split[1]; //incorrect, outofrange exception (Month)
    textbox3.Text = split[2]; //incorrect, outforange exception (Year)

NOTE: The format is Day/Month(words)/Year ==> 1/January/2012

Can somebody help me get that values and put them one by one in a textbox?
