使用重载机制替代可选参数：SonarQube构建报错代码修改咨询

Alright, let's tackle this SonarQube issue by swapping out that optional parameter with method overloading—super straightforward once you see how it works. Here's how to refactor your code cleanly:

Step 1: Split into two overloaded Strings methods #

Instead of using a single method with an optional parameter, we'll create two distinct methods: one that takes no arguments, and another that accepts a CultureInfo parameter. This keeps logic clear and aligns with SonarQube's recommendations.

// Overload 1: No parameters, uses the current UI culture by default
public ActionResult Strings()
{
    // Delegate to the parameterized version with our default value
    return Strings(CultureInfo.CurrentUICulture);
}

// Overload 2: Accepts a specific CultureInfo parameter
public ActionResult Strings(CultureInfo id)
{
    // Keep your original logic (we still handle nulls just in case)
    CultureInfo cultureInfo = id ?? CultureInfo.CurrentUICulture;
    
    // Rest of your method's existing logic goes here...
}

Why this works #

• This completely removes the optional parameter that SonarQube is flagging.
• The overloaded methods make intent explicit: callers can either provide a custom CultureInfo or rely on the default current UI culture without ambiguity.
• We keep core logic centralized in the parameterized method, avoiding code duplication.

If you want to enforce non-null inputs for the parameterized method (since the no-arg overload passes a valid CultureInfo), you could add a null check—but keeping the ?? fallback ensures backward compatibility if someone directly calls the parameterized method with a null value.
