有没有机会使用Linq(C#)获得独特的记录？

List<string> names = new List<string> { "Alice", "Bob", "Alice", "Eve", "Bob" };
var uniqueNames = names.Distinct();

List<Customer> customers = new List<Customer>
{
    new Customer { Name = "Alice", Age = 30 },
    new Customer { Name = "Bob", Age = 25 },
    new Customer { Name = "Alice", Age = 30 },
    new Customer { Name = "Eve", Age = 22 },
    new Customer { Name = "Bob", Age = 25 }
};

var uniqueCustomers = customers.GroupBy(c => new { c.Name, c.Age });

List<string> names = new List<string> { "Alice", "Bob", "Alice", "Eve", "Bob" };
HashSet<string> uniqueNames = new HashSet<string>(names);

List<Customer> customers = new List<Customer>
{
    new Customer { Name = "Alice", Age = 30 },
    new Customer { Name = "Bob", Age = 25 },
    new Customer { Name = "Alice", Age = 30 },
    new Customer { Name = "Eve", Age = 22 },
    new Customer { Name = "Bob", Age = 25 }
};

var uniqueCustomers = customers.GroupBy(c => new { c.Name, c.Age })
                               .Select(g => g.First());
