C＃动态条件 [英] C# dynamic condition

问题描述

我有一个场景需要针对类对象属性评估动态条件。

示例：我有一个Person类，它有一些属性Age，Name，City，Pincode等。

现在从文本框值开始，我将得到字符串条件，如（年龄= 23，城市=伦敦或Pincode = 123）。这些条件是动态的。我需要针对人类对象检查这些条件。

考试：

if（objPerson.Age == 23&& objPerson.city == London || objPerson.Pincode == 123）

做一些事情



有没有一种简单的方法可以在运行时根据person类对象属性值来评估这些条件。



我的尝试：

I have a scenario where I need to evaluate a dynamic condition against the class object property.
Example :I have a Person class which have some property Age,Name,City,Pincode etc.
now from text box value ,I will get the string condition like (Age=23 and City=London or Pincode =123).These condition is dynamic.i need to check these condition against the person class object.
exam:
if(objPerson.Age==23 && objPerson.city==London ||objPerson.Pincode ==123)
do some thing

Is there an easy way to evaluate these condition at run time against the person class object property value.

了解如何使用Google，或者您作为开发人员的职业生涯将会很短。

Of course, you have to replace " and " and " or " with their appropriate C# operators in the string first...

I also found this (which might be more appropriate):
