我们都是直接使用LINQ作为查询接口,VS在最后编译的时候负责对LINQ的语法进行解析并且翻译成对应的扩展方法调用。...我们忽视一个重要的环节,就是VS对LINQ进行解析翻译的时候是会执行LINQ表达式的,这点非常重要。...之前我一直以为VS只负责将LINQ的表达式翻译成等价的扩展方法调用,后来发现VS为了满足我们在前期无法确定对象条件的情况下进行Where字句的拼接,允许我们在编写LINQ语句的时候带有逻辑判断表达式在里面...表达式的处理可以分为常量表达式和动态变量表达式,常量表达式在VS编译的时候就可以直接计算表达式是否是true、false。...对照链式方法,很明显VS先对1==1表达式进行了执行并返回true作为后面整个表达式的一部分拼接进Where链式方法,所以先执行再解析两个过程。
