If you want to add the id manually you can use,

PadLeft() or String.Format() method.

string id;
char x='0';
id=id.PadLeft(6, x);
//Six character string id with left 0s e.g 000012

int id;
id=String.Format("{0:000000}",id);
//Integer length of 6 with the id. e.g 000012

Then you can append this with UID.
