British number twos Dart and Norrie caused upsets on Thursday when they knocked out their higher-ranked compatriots on Court One.
The in-form Katie Boulter and Jack Draper, both seeded at Wimbledon for the first time, were expected to go deep in the tournament.
It is the first time that Dart, ranked 94th, has reached the third round of a Grand Slam since 2019.
“I’m super excited to be back in the third round, it’s been a really long time so to be back feels like a real hurdle that I’ve jumped through,” she said.
Dart, who won her previous encounter with 42nd-ranked Wang, added: “I’m a completely different player. I have improved so much and I feel like I am playing much better tennis.”
Meanwhile, Norrie faces fourth seed and French Open finalist Zverev, who has been the victor in all five of their meetings.
“It’s a tough draw but I’m looking forward to testing myself against Sascha – he’s had an unbelievable year, I think it’s the best year he’s had so far on tour,” said 2022 semi-finalist Norrie.
