在struct中声明整数

Question

My code is a service that needs to output different status codes as follows:

if(something is valid)
{
  if(this is found)
    return "200";
  else
    return 300;
}
else
   return "100";

There are many such status codes and also occur at various places in the application. So, I would like to declare them as constants at one place and use them, so as not to hard code the strings.

something like

public struct StatusCodes
{
  public static string 100 = "100";
  public static string 200 = "200";
}

and be able to use it as

else return StatusCodes.100

Is there a standard practice or a good way to do so.

Answer 1

I suggest using a enum :

  public enum Status {
    One = 100,
    Another = 200
  }

....

  if (some condition)
    return Status.One;
  else
    return Status.Another;

Answer 2

How about this:

public static class StatusCodes
{
  public const string Code100 = "100";
  public const string Code200 = "200";
}

and you can use it as:

return StatusCodes.Code100

Answer 3

It is better in your case( if you really have a lot of statuses) to create a static class with public fields as:

public const string myStatus= "100";

So your statuses will be stored in one place. And there you can write MyClass.myStatus
