C# Orderby（对开发人员的工作原理）

var sortedCollection = collection.OrderBy(item => item.OrderByProperty);

Dim sortedCollection = collection.OrderBy(Function(item) item.OrderByProperty)

var sortedCollectionDesc = collection.OrderByDescending(item => item.OrderByProperty);

Dim sortedCollectionDesc = collection.OrderByDescending(Function(item) item.OrderByProperty)

var multiSortedCollection = collection
    .OrderBy(item => item.OrderByProperty1)
    .ThenByDescending(item => item.OrderByProperty2);

Dim multiSortedCollection = collection.OrderBy(Function(item) item.OrderByProperty1).ThenByDescending(Function(item) item.OrderByProperty2)

var customSortedCollection = collection.OrderBy(item => item.Property, new CustomComparer());

Dim customSortedCollection = collection.OrderBy(Function(item) item.Property, New CustomComparer())
