动态Linq - String.Split [英] Dynamic Linq - String.Split

问题描述

看来，LINQ的动态没有实现String.Split方法。

It appears that Dynamic Linq doesn't implement the String.Split method.

有没有办法实现与动态LINQ的？

Is there a way achieve the same results with Dynamic Linq ?

推荐答案

动态LINQ的不支持String.Split，也呼吁其他.NET类型的方法如下所示

Dynamic Linq does support String.Split and also calling other .net type methods as shown below

var query =
                db.Customers.Where("City.Split(\"abc\".ToCharArray()).Length == 1 and Orders.Count >= @1", "London", 10).
                OrderBy("CompanyName").
                Select("New(CompanyName as Name, Phone)");

这是能够将字符串转换为表达式树但SQL没有任何字符串分割操作它会引发错误，如果你在SQL

It was able to convert the string to expression tree but as SQL doesn't have any string split operation it throws error if you run it on SQL
