Static helper class/method design question

As for the caching logic, I don't really see a problem with it as long as you know the types for a given path wouldn't change during runtime.

Static helper class/method design question

For testability's sake, I'd personally make this a non-static class with an interface (with _pathCache being a non-static field). You can then register this class as a singleton to be injected into your other classes. Then for the FillCache method, you can either call that in the constructor (although typically you would avoid complex logic like that in a constructor) or maybe call it when registering your class.

405 Method Not Allowed

From the error it sounds like whatever endpoint you're trying to hit doesn't support whatever http method you're sending.

_http.PostAsJsonAsync("api/permit", permit);

_http.PostAsJsonAsync("api/permit", permit);

This suggests you're sending a POST, but does that endpoint actually support a POST? Or if it does, does the PostAsJsonAsync method actually send it as a POST?

❔ ✅ Help with searching a class of classes for something?

Assuming you have this sort of structure:

public EntryClass
{
  public string Name { get; set; }
  public string SomethingSpecial { get; set; }
}

public MiddleClass
{
  public List<EntryClass> EntryClasses { get; set; }
}

public StartingClass
{
  public List<StartingClass> MiddleClasses { get; set; }
}

public EntryClass
{
  public string Name { get; set; }
  public string SomethingSpecial { get; set; }
}

public MiddleClass
{
  public List<EntryClass> EntryClasses { get; set; }
}

public StartingClass
{
  public List<StartingClass> MiddleClasses { get; set; }
}

Then you would need to iterate over over every MiddleClass inside of StartingClass's list, and inside each one of those MiddleClass object, iterate over that list until you find your target. So something like:

public EntryClass FindTarget(StartingClass startingClass, string nameTarget) 
{
  foreach (var middleClass in startingClass.MiddleClasses)
  {
    foreach (var entryClass in middleClass.EntryClasses)
    {
      if (entryClass.Name == nameTarget)
        return entryClass;
    }
  }

  // we have iterated over every possible EntryClass and none had the "nameTarget"
  return null;
}

public EntryClass FindTarget(StartingClass startingClass, string nameTarget) 
{
  foreach (var middleClass in startingClass.MiddleClasses)
  {
    foreach (var entryClass in middleClass.EntryClasses)
    {
      if (entryClass.Name == nameTarget)
        return entryClass;
    }
  }

  // we have iterated over every possible EntryClass and none had the "nameTarget"
  return null;
}

If the nesting of your classes is more "deep" you would just add more for loops.

❔ Singleton Pattern StackOverflowException

Your Instance property checks if Instance (itself) is null, but that only calls the Instance getter which you are already in

Declare a private _instance field and have your Instance getter and setter get/set the field instead of getting and setting itself.
