Question

Can I do something like this:

Configs.Environment.Development;

I'm currently doing something like this:

Configs.Environment == "DEV";

I don't particularly care for the strings, but I don't know how to set "specific" properties or if it's possible.

Answer 1

Are you talking about enums?

public enum Environment
{
    Development,
    Test,
    Live
}


Configs.Environment = Environment.Development;

Answer 2

This sounds like the sort of thing that's better handled by a preprocessor directive:

#if debug
/* etc */
#elseif production
/* etc */
#endif

Answer 3

您可以通过使Environment成为枚举或使Development成为静态只读字符串来实现。

Answer 4

Yes.

 public static class Configs{
         public static class Environment{
              public static readonly string Development="DEV";
          }

  }

But you probably want ENUMS, and use a factory to set your constants.

Answer 5

Do you want the setting to take effect at compile time only or at runtime? Do you want your user to be able to select different settings after deployment?

If you want a compile time only setting, then a pre-processor directive is what you want.

If you want runtime settings, .NET has direct support for .config files and you can access the values in your code (and set them too) via the Settings.Default constructs.

VisualStudio has support for easily creating and maintaining these config files.
