像Linq中的运算符(对于整数) [英] Like operator in Linq(For integer)

问题描述

在Linq中，我们对字符串使用like运算符
即
从ctx中的

In Linq we use the like operator for strings
i.e,

var query = from c in ctx.Customers
            where c.City.StartsWith("L") && c.City.Contains("n")
            select c;

是否有可能像linq一样对整数应用运算符.

请帮助我.

Is it Possible to apply like operator in linq for integers.

please help me.

推荐答案

除非将int转换为字符串，否则"like"运算符将无法使用:您不能在其中指定整数以7开头"或以23结尾"的术语-只是没有任何语法可以做到这一点.您可以只对所需的值进行比较，也可以使用模数运算符提取相关信息.

您要达到什么目的，以为您认为自己需要这个?

Unless you convert the int to a string, the "like" operator has nothing to work from: you can''t specify an integer in terms of "starts with a 7" or "ends with 23" - there just isn''t any syntax to do that. You could just use a comparison against the values you want, possibly using the modulus operator to extract relevant information.

What are you trying to achieve that you think you need this?
