使用IndexOf切换的最佳方法 [英] Best way to use switch with IndexOf

问题描述

大家好，



我正在寻找关于使用带有一些字符串的switch语句的一些信息，我不知道是否可能或最好的方式我正在寻找一些建议。我将发布一个片段，以便每个人都能得到这个想法。



感谢帮助。

Hi Everyone,

I am looking for some info on using a switch statement with some strings, I don't know if it's possible or the best way as I am looking for some advice at the moment. I am going to post a snippet so everyone will get the idea.

Appreciate the help.

string testing "This is a local state Florida";
string state = string.Empty;

switch(testing)
{
case "Louisiana":
if(testing.IndexOf("Louisiana") > -1)
 state = "Louisiana";
 break;

case "California":
if(testing.IndexOf("California") > -1)
 state = "California";
 break;

case "Florida";
if(testing.IndexOf("Florida") > -1)
 state = "Florida";
 break;

default:
  state = "";
}

推荐答案

您的代码无法运行，因为testing的值不能满足您的任何需求案例陈述

Your code isn't going to work as the value of "testing" does not satisfy any of your case statements

string testing = "This is a local state Florida";

List<string> states = new List<string>{"Louisiana", "California", "Florida"};

string state = states.FirstOrDefault(s => testing.IndexOf(s) != -1);
