Never heard of White Collar. Looking it up in Wikipedia, it looks almost like a retread of Switch.
I presume you mean the 1975 Glen Larson series with Eddie Albert and Robert Wagner, which I had to look up, since I don't remember it. It's a similar premise, a cop and a con man solving crimes together, but it's quite different. Albert's character was a retired cop and the two opened a private detective agency after Wagner's character got out of prison -- which reminds me of the short-lived Stephen J. Cannell series Tenspeed and Brown Shoe, where straitlaced ex-stockbroker Jeff Goldblum and con artist Ben Vereen formed a detective agency together. White Collar is about a debonair gentleman thief and forger compelled to work as a criminal informant for an active FBI agent as a condition of his parole. The friendship and tension between the partners with conflicting agendas and values was the heart of the show. It's kind of like if Lupin III had to work for Inspector Zenigata.
