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);
}

你可以将IEnumerable转换为IQueryable。

items = items.AsQueryable().OrderBy("Name ASC");

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}");

感谢Maarten(在LINQ中使用PropertyInfo对象查询一个集合)，我得到了这个解决方案:

myList.OrderByDescending(x => myPropertyInfo.GetValue(x, null)).ToList();

在我的情况下，我在一个“ColumnHeaderMouseClick”(WindowsForm)上工作，所以只发现特定的列按下及其对应的PropertyInfo:

foreach (PropertyInfo column in (new Process()).GetType().GetProperties())
{
    if (column.Name == dgvProcessList.Columns[e.ColumnIndex].Name)
    {}
}

OR

PropertyInfo column = (new Process()).GetType().GetProperties().Where(x => x.Name == dgvProcessList.Columns[e.ColumnIndex].Name).First();

(确保你的列名称与对象属性匹配)

干杯

经过大量的搜索，这对我来说很有效:

                                                    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]);
    }
}
