Backspace in string formatting while writing in PDF

I'm trying to print in PDF two columns of information that contain some strings that the user inputs. This is my code so far:

string s = "";                                                                  
s = s + string.Format("{0,-60}", "Name: " + name);
s = s + string.Format("{0,15}","AAA: ");
p1.Add(s);
document.Add(p1);

string p = "";                                                                 
p = p + string.Format("{0,-60}", "Surname: " + surname);
p = p + string.Format("{0,15}","BBB: ");
p2.Add(p);
document.Add(p2);

string r = "";                                                        
r = r + string.Format("{0,-60}", "School: " + school);
r = r + string.Format("{0,15}","CCC: ");
p3.Add(r);
document.Add(p3);

If the user enters, for example, "John Edward Jr." for name, "Pascal Einstein W. Alfi" for surname and "St. John" for school, then the expected output is something like this:

Name: John Edward Jr.________________AAA:

Surname: Pascal Einstein W. Alfi_______BBB:

School: St. John___________________CCC:
I suppose the spaces in every string name, surname and school are the problem. How can I deal with this?

EXPECTED OUTPUT:

Name: John Edward Jr._________________AAA:

Surname: Pascal Einstein W. Alfi_______BBB:

School: St. John________________________CCC:
