GameFramework摘录

访问器模式
Version、Logger等基础模块，功能相对固定但拥有几套不同的行为（如开发版本和正式版本不同），采用访问器模式，便于调整功能或复用

public static class Version
{
	public interface IVersionHelper
	{
		string GameVersion { get; }
	}
	
	private static IVersionHelper s_VersionHelper = null;
	
	public static string GameVersion {
		get
		{
			if (s_VersionHelper == null)
			{
				return string.Empty;
			}
			
			return s_VersionHelper.GameVersion;
		}
	}
	
	public static void SetVersionHelper(IVersionHelper versionHelper)
	{
		s_VersionHelper = versionHelper;
	}
}

Version类的公共属性都通过访问器进行访问，访问器可自定义

class MyVersionHelper : Version.IVersionHelper
{
	public string GameVersion
	{
		get
		{
			return "test gameversion!";
		}
	}
}

static void Test()
{
	Version.SetVersionHelper(new MyVersionHelper());
	Console.WriteLine(Version.GameVersion);	// test gameversion!
}
