To use multiple `OrderBy()` in LINQ, you can use the `ThenBy()` method. The `ThenBy()` method takes a lambda expression as its parameter and sorts the list by the property specified by the lambda expression. The following code sorts a list of `Person` objects by their age in ascending order, and then by their name in descending order:

C#

```plaintext
var people = new List<Person>();
people.Add(new Person { Age = 20, Name = "John" });
people.Add(new Person { Age = 30, Name = "Jane" });
people.Add(new Person { Age = 10, Name = "Peter" });

var sortedPeople = people.OrderBy(p => p.Age).ThenBy(p => p.Name);
```

In this code, the `OrderBy()` method sorts the list by the `Age` property of the `Person` objects in ascending order. The `ThenBy()` method then sorts the list by the `Name` property of the `Person` objects in descending order.

You can also use the `ThenByDescending()` method to sort the list by the property specified by the lambda expression in descending order. The following code is equivalent to the previous code:

C#

```plaintext
var sortedPeople = people.OrderBy(p => p.Age).ThenByDescending(p => p.Name);
```
