You should use user's First Name and also generate a RandomString with a RandomNumber and combine all three to generate a strong Random User Name.

Search this site for Random String and Random Number to learn how to generate a random number and a random string.

ok, But maybe some user may share same first name and last name. Conflict may arise on that time. you can generate a random numbers and concatenate with firstname or both firstname last name to get the UserName.
Go through with following article to generate randam number in C#.

well you can always use the firstname.Lastname as UserName

and if you want you have 1 already just add to it a 3 letter number starting from 001 to 999

but the client requirement is tht only. so i have to do tht. any one have any idea to do ths.

I think giving first name as user name is not a good idea. You can always ask for user email address which is always unique and give them it as username.
