How to Implement Dynamic LINQ Ordering for `IEnumerable` and `IEnumerable`?

/ The dynamic linq sort IEnumerable<t></t> IQueryable<t></t>

Expansion method

IEnumerable<t></t> Although the dynamic Linq provides convenient syntax for sorting, similar functions are not directly applicable to

. To solve this problem, you can use the following extension methods to add

, IQueryable<t></t>, IEnumerable<t></t> and IEnumerable<t></t> Function: OrderBy OrderByDescending ThenBy Use ThenByDescending

together with

public static IOrderedQueryable<T> OrderBy<T>(
    this IQueryable<T> source,
    string property)
{
    return ApplyOrder<T>(source, property, "OrderBy");
}

public static IOrderedQueryable<T> OrderByDescending<T>(
    this IQueryable<T> source,
    string property)
{
    return ApplyOrder<T>(source, property, "OrderByDescending");
}

public static IOrderedQueryable<T> ThenBy<T>(
    this IOrderedQueryable<T> source,
    string property)
{
    return ApplyOrder<T>(source, property, "ThenBy");
}

public static IOrderedQueryable<T> ThenByDescending<T>(
    this IOrderedQueryable<T> source,
    string property)
{
    return ApplyOrder<T>(source, property, "ThenByDescending");
}

static IOrderedQueryable<T> ApplyOrder<T>(
    IQueryable<T> source,
    string property,
    string methodName)
{
    // 为简洁起见，省略实现
}

To use these extensions with , you can use the IEnumerable<t></t> expansion method to convert it to :

IEnumerable<t></t> Use AsQueryable Dynamic sorting IQueryable

IEnumerable<T> items = ...;
IQueryable<T> queryableItems = items.AsQueryable();

var orderedItems = queryableItems.OrderBy("Property");

In addition to the basic sorting method, you can also use

dynamic sorting to further expand the function. This is an example:
