❔ How would you refactor something like this? Is there a pattern that could help me?

Is there a way to clean something like this up? I've got a lot of evaluations to perform based on a bunch of different bool settings

void Main()
{
    GetResult();
}

public Result GetResult()
{
    var result = new Result();

    bool condition1overridesCondition2 = true; // Configuration value
    bool condition2 = true;
    bool? condition3overridesCondition3 = true;
    bool? condition4 = false;
    
    // ... more conditions

    if (!condition1overridesCondition2)
    {
        result.Valid = false;
        result.Reason = "A";
        return result;
    }
    
    if (!condition2) {
        result.Valid = false;
        result.Reason = "B";
    }
    
    if (condition3overridesCondition3 != true) {
        result.Valid = false;
        result.Reason = "C";
    }
    
    result.Valid = condition4 == true;
    result.Reason = "D";
    
    
    // ... More evaluations
    
    return result;
}

public class Result
{
    public string Reason { get; set; }
    public bool Valid { get; set; }
}

void Main()
{
    GetResult();
}

public Result GetResult()
{
    var result = new Result();

    bool condition1overridesCondition2 = true; // Configuration value
    bool condition2 = true;
    bool? condition3overridesCondition3 = true;
    bool? condition4 = false;
    
    // ... more conditions

    if (!condition1overridesCondition2)
    {
        result.Valid = false;
        result.Reason = "A";
        return result;
    }
    
    if (!condition2) {
        result.Valid = false;
        result.Reason = "B";
    }
    
    if (condition3overridesCondition3 != true) {
        result.Valid = false;
        result.Reason = "C";
    }
    
    result.Valid = condition4 == true;
    result.Reason = "D";
    
    
    // ... More evaluations
    
    return result;
}

    public string Reason { get; set; }
    public bool Valid { get; set; }
}

This is interesting, I'll give it a shot. I had the idea of making it a class of its own but I wasn't sure if the RulesEngine approach would work

the answer is obviously CallerArgumentExpression lmao

RyaliaOP•16mo ago

Reason being that some of these "rules" short circuit the evaluation and I don't want to evaluate the rest

Something like this maybe? (Obviously not gonna copy paste) https://yiniski.medium.com/rule-engine-pattern-8a3f0e0c2d81 The business idea is that: I'm trying to build something (I guess a rule engine) that determines whether something should be done. Got a whole bunch of configurations So something e.g. MasterSwitchThatShutsDownTheEntireOperation will stop and short circuit the rest but e.g. ConditionOneThatNeedsToBeSuccessfulAlongWithOtherConditions will need to continue evaluating other conditions

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
