从表添加和检索键值对

Question

I have a (read only) table containing some config info, for example:

Red  -  1,
Green - 2,
Orange - 3.

What is the easiest way to load this into some collection, so that I can write, for example:

byte x = MyColl.Red;

Answer 1

One option would be to use an enum

The enum keyword is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list.

The problem with this is that it needs to be hard coded at compile time, so reading it from a table will not make sense.

The other option would be tio use Dictionary Class

Represents a collection of keys and values.

where you could look at

Dictionary<string, byte>

So as to use it such that

byte x = MyCollDictionary["Red"];
