Methods

OrderByIf<T, TQueryable>(TQueryable, bool, string)

Order a IQueryable<T> by given predicate if given condition is true.

public static TQueryable OrderByIf<T, TQueryable>(this TQueryable query, bool condition, string sorting) where TQueryable : IQueryable<T>

condition bool

A boolean value

sorting string

Order the query

Returns

TQueryable

Order or not order query based on condition
