LINQ WHERE与OR [英] LINQ WHERE with OR

问题描述

我使用LINQ来创建我的where子句，如下所示:

I use LINQ to create my where clause like so:

var query = from x in context.Xs
            select x;

if (y == ...)
{
    query = query.Where(x => x.Y == 1);
}

我有一堆这样的"if .... where"语句.我的问题是所有这些wheres都使用AND联接where子句，但是我需要我所有的where子句才能使用OR.有没有简单的方法可以将此代码移植到OR代码所在的位置?甚至用OR做到这一点的最简单方法是什么?

I have bunch of these "if .... where" statements. The issue I have is that all of those wheres join where clauses using AND but I need all my where clauses to use OR. Is there an easy way to port this code into where OR code? Or even what is the easiest way to do this with OR?

谢谢.
