问题描述

How can i perform an LIKE query within Linq?

I have the following query i would like to execute.

var results = from c in db.costumers
              where c.FullName LIKE "%"+FirstName+"%,"+LastName
              select c;

解决方案

You could use SqlMethods.Like(matchExpression,pattern)

var results = from c in db.costumers
              where SqlMethods.Like(c.FullName, "%"+FirstName+"%,"+LastName)
              select c;

The use of this method outside of LINQ to SQL will always throw a NotSupportedException exception.
