arcobjects - Is there any way to write a snipet of code with function of "SDELayer -o register" command

I try to create a geodatabase using some SQL command and then register some tables of it with SDE.

I create an empty geodatabase using sde post installation and then create tables and other database objects in a program written by VC# using command like "Create Table" and other DDL scripts.

but after creating database successfully user of this VC# program has to enter "Command prompt" and type sdelayer command to register tables one by one.

I need to make all the process seamless for user and user must not see any change in working environment.Now my question,is there any way that I register tables of my geodatabse with SDE by VC# code programming instead of using "sdelayer" command in command prompt?(Any object model?)
