C#/.NET 泛型+索引器搭建通用字典Dictionary

	public enum Types
	{
		X,
		Y,
		Z,
		W
	}
	public class DemoInfoMap<T>
	{
		private Dictionary<Types, T> demoMap = new Dictionary<Types, T>();

		public DemoInfoMap()
		{
			this.demoMap.Add(Types.X, default(T));
			this.demoMap.Add(Types.Y, default(T));
			this.demoMap.Add(Types.Z, default(T));
			this.demoMap.Add(Types.W, default(T));
		}

		//索引器参数需跟字典的key一样
		public T this[Types axis]
		{
			get
			{
				return this.demoMap[axis];
			}
			set
			{
				this.demoMap[axis] = value;
			}
		}
		public DemoInfoMap<UInt32> DemoInfo
		{
			get
			{
				var demoInfo = new DemoInfoMap<UInt32>();
				demoInfo[Types.X] = 2;
				return demoInfo;
			}
		}
	}

调用

	public DemoInfoMap<UInt32> DemoStatusInfo
	{
		get
		{
			var statusInfo = new DemoInfoMap<UInt32>();
			statusInfo[Types.X] = 2;
			return statusInfo;
		}
	}
	public void DemoControl()
	{
		var index = DemoStatusInfo[Types.X];
	}
