只需检查多个语句C# [英] Simply check for multiple statements C#

问题描述

目前正在开发一款小型主机游戏，想知道是否有人有一种简单的方法来缩短此类内容:

Currently working on a small console game and was wondering if anyone has a simple way to shorten something like this:

if (map[playerX - 1, playerY] == "R1"
 || map[playerX - 1, playerY] == "R2"
 || map[playerX - 1, playerY] == "R3"
 || map[playerX - 1, playerY] == "Z1" 
 || map[playerX - 1, playerY] == "Z2" 
 || map[playerX - 1, playerY] == "Z3"
 || map[playerX - 1, playerY] == "S1 " 
 || map[playerX - 1, playerY] == "S2" 
 || map[playerX - 1, playerY] == "S3")

制作一个列表或某物，并检查map[playerX-1, playerY]是否等于其中的任何对象或物.

making a list or something and checking if map[playerX-1, playerY] is equal to any of the objects in it or something.

非常感谢您的帮助. 卢卡斯·莱德(Lukas Leder)

推荐答案

您感兴趣的特定匹配值(R1，Z1等)应填充到HashSet中.

The particular matching values you are interested in (R1, Z1 etc) should be populated into a HashSet.

HashSet hashSet = new HashSet<string>
{
    "R1",
    "R2",
    "R3",
    "Z1",
    "Z2",
    "Z3",
    "S1 ", // I am unclear whether you want this space or not
    "S2",
    "S3"
};

然后使用:

if (hashSet.Contains(map[playerX - 1, playerY])

HashSet具有始终如一的快速

HashSet has a consistently fast Contains function (shown above) which will suit your purposes. As @FilipCordas mentions below, you should consider declaring this HashSet as a static readonly field to ensure you only need to initialise it once.
