Question

Is it possible to evaluate the following in C# at runtime

I have a class that contains 3 properties (Field,Operator,Value)

 rule.Field;
 rule.Operator;
 rule.Value;

this is my rule class…

Now I have a loop

foreach(item in items)
   {
       // here I want to create a dynamic expression to evaluate at runtime
       // something like
       if (item.[rule.field] [rule.operator] [rule.value])
           { do work }
   }

I just don’t know the syntax, or if its possible in C#, I know in JS its possible but that’s not a compiled language.

Update

Essentially I want a way to eval(stringCode) or a better more supported way.

I’m not entirely sure what you are saying. Can you try clarifying it a bit?

Are you wanting to to take a string expression and evaluate it at runtime in C#? If so the answer is no. C# does not support such types of dynamic evaluation.
