你可以这样做，对多个顺序

IOrderedEnumerable<JToken> sort;

if (query.OrderBys[0].IsDESC)
{
    sort = jarry.OrderByDescending(r => (string)r[query.OrderBys[0].Key]);
}
else
{
    sort = jarry.OrderBy(r =>
        (string) r[query.OrderBys[0].Key]); 
}

foreach (var item in query.OrderBys.Skip(1))
{
    if (item.IsDESC)
    {
        sort = sort.ThenByDescending(r => (string)r[item.Key]);
    }
    else
    {
        sort = sort.ThenBy(r => (string)r[item.Key]);
    }
}

经过大量的搜索，这对我来说很有效:

public static IEnumerable<TEntity> OrderBy<TEntity>(this IEnumerable<TEntity> source, 
                                                    string orderByProperty, bool desc)
{
    string command = desc ? "OrderByDescending" : "OrderBy";
    var type = typeof(TEntity);
    var property = type.GetProperty(orderByProperty);
    var parameter = Expression.Parameter(type, "p");
    var propertyAccess = Expression.MakeMemberAccess(parameter, property);
    var orderByExpression = Expression.Lambda(propertyAccess, parameter);
    var resultExpression = Expression.Call(typeof(Queryable), command, 
                                           new[] { type, property.PropertyType },
                                           source.AsQueryable().Expression, 
                                           Expression.Quote(orderByExpression));
    return source.AsQueryable().Provider.CreateQuery<TEntity>(resultExpression);
}

你可以添加它:

public static IEnumerable<T> OrderBy( this IEnumerable<T> input, string queryString) {
    //parse the string into property names
    //Use reflection to get and sort by properties
    //something like

    foreach( string propname in queryString.Split(','))
        input.OrderBy( x => GetPropertyValue( x, propname ) );

    // I used Kjetil Watnedal's reflection example
}

GetPropertyValue函数来自Kjetil Watnedal的答案

问题是为什么?任何这样的排序都会在运行时抛出异常，而不是在编译时抛出异常(如D2VIANT的答案)。

如果你正在处理Linq to Sql, orderby是一个表达式树，它将被转换为Sql以执行。

var result1 = lst.OrderBy(a=>a.Name);// for ascending order. 
 var result1 = lst.OrderByDescending(a=>a.Name);// for desc order. 

使用动态linq

使用System.Linq.Dynamic添加即可;

然后像这样用它来排列你所有的列:

string sortTypeStr = "ASC"; // or DESC
string SortColumnName = "Age"; // Your column name
query = query.OrderBy($"{SortColumnName} {sortTypeStr}");

如果您正在使用规范(例如Ardalis规范)

using Microsoft.EntityFrameworkCore;

namespace TestExtensions;

public static class IQueryableExtensions
{
    public static void ApplyOrder<T>(ISpecificationBuilder<T> query, string propertyName, bool ascendingOrder)
    {
        if (ascendingOrder)
            query.OrderBy(T => EF.Property<object>(T!, propertyName));
        else
            query.OrderByDescending(T => EF.Property<object>(T!, propertyName));
    }
}
