使用反射自定义if语句 [英] Custom if statement using reflection

问题描述

嘿，如果可以将文本解析为if语句，并且也添加了and，or和xor，那么我全神贯注，所以可以说我是否在列表中有一些标记，如下所示:
如果某变量，等值，另一个变量和/或/或某变量等值或第三变量做某事.

应该翻译成if(var1 == var2 &&/||/^ var1 == var3){body}

目前，我可以使它适用于单个语句/布尔表达式，但是我真的迷失了如何使用反射来检查乘法.它必须与ands和ors进行两次以上的比较，因此它必须能够将它称为递归性.因此，如果有任何解决方案，我希望收到您的回音-非常感谢.

Hey all i was wondring if it is possible to parse text to an if statement and also have and, or, and xor added to so lets say if i have some tokens in a list as following:
if, someVarible, isequal, anothervarible, and /or/xor someVarible isequal aathirdvarible do something.

that should be translated into if(var1 == var2 &&/||/^ var1 == var3) { body }

at the moment i can make it work for a single statement/boolean expression but im really lost how i can check for multiply by using the reflections. it migth be more than 2 comparisons that is needed with both ands and ors so it must be able to call it recrusive. so if any one out there have a solution i would love to hear from you - thanks a lot.
