.NET Framework LINQ ThenBy
Example
ThenBy can only be used after a OrderBy clause allowing to order using multiple criteria
var persons = new[]
{
new {Id = 1, Name = "Foo", Order = 1},
new {Id = 1, Name = "FooTwo", Order = 2},
new {Id = 2, Name = "Bar", Order = 2},
new {Id = 2, Name = "BarTwo", Order = 1},
new {Id = 3, Name = "Fizz", Order = 2},
new {Id = 3, Name = "FizzTwo", Order = 1},
};
var personsSortedByName = persons.OrderBy(p => p.Id).ThenBy(p => p.Order);
Console.WriteLine(string.Join(",", personsSortedByName.Select(p => p.Name)));
//This will display :
//Foo,FooTwo,BarTwo,Bar,FizzTwo,Fizz
