英文:
StartsWith() with an array of strings
问题
让我们假设我有一个字符串数组：
string[] greeting = new string[] {"hey", "hello", "hi"};
如果用户输入是以下任何一个词语："hey"、"hello"、"hi"，那么我希望控制台输出 "hey there"。这是我做的：
string userInput = Console.ReadLine();
bool result_a = greeting.Contains(userInput);
if (result_a) { Console.WriteLine("hey there"); }
但似乎不起作用。
英文:
Let's say I have an array of strings:
string[] greeting = new string[] {"hey", "hello", "hi"};
if the user input is any of the following words: "hey" "hello" "hi" then I want the console to print "hey there". This is what I did:
string userInput = Console.ReadLine();
bool result_a = userInput.StartsWith(greeting);
if(result_a) { Console.WriteLine("hey there"); }
but that doesn't seem to be working.

以下是翻译好的内容：
如果您想要的是，每当用户以以下任何一种方式开始时：
using System;
using System.Linq;
...
string[] greeting = new string[] {"hey", "hello", "hi"};
string userInput = Console.ReadLine();
bool result_a = greeting.Any(a => userInput.Trim().StartsWith(a));
if(result_a) { Console.WriteLine("hey there"); }
示例：“hi 我的名字是 Ali”
现在，如果您希望大写字母也能正常工作，您需要更改以下行：
示例：“Hi 我的名字是 Ali”
bool result_a = greeting.Any(a => userInput.Trim().ToLower().StartsWith(a));
如果您想要的是，每当用户输入包含以下内容时：
using System;
using System.Linq;
...
string[] greeting = new string[] {"hey", "hello", "hi"};
string userInput = Console.ReadLine();
bool result_a = greeting.Any(a => userInput.Trim().Contains(a));
if(result_a) { Console.WriteLine("hey there"); }
示例：“早上好！hello”
现在，如果您希望大写字母也能正常工作，您需要更改以下行：
示例：“早上好！Hello”
bool result_a = greeting.Any(a => userInput.Trim().ToLower().Contains(a));
英文:
If what you want is, whenever the user starts with any of the 3
using System;
using System.Linq;
...
string[] greeting = new string[] {"hey", "hello", "hi"};
string userInput = Console.ReadLine();
bool result_a = greeting.Any(a => userInput.Trim().StartsWith(a));
if(result_a) { Console.WriteLine("hey there"); }
Example: "hi my name is Ali"
Now if you want capital letters to work as well you need to change the line to:
Example: "Hi my name is Ali"
bool result_a = greeting.Any(a => userInput.Trim().ToLower().StartsWith(a));
If what you want is, whenever the user input contains then:
using System;
using System.Linq;
...
string[] greeting = new string[] {"hey", "hello", "hi"};
string userInput = Console.ReadLine();
bool result_a = greeting.Any(a => userInput.Trim().Contains(a));
if(result_a) { Console.WriteLine("hey there"); }
Example: "Good morning! hello"
Now if you want capital letters to work as well you need to change the line to:
Example: "Good morning! Hello"
bool result_a = greeting.Any(a => userInput.Trim().ToLower().Contains(a));

string[] greeting = new string[] { "hey", "hello", "hi" };
string userInput = Console.ReadLine();
bool result_a = greeting.Any(x => x.StartsWith(userInput));
if (result_a) { Console.WriteLine("hey there"); }
if (result_a) { Console.WriteLine($"{greeting.FirstOrDefault(x => x.StartsWith(userInput))} there"); }
英文:
string[] greeting = new string[] { "hey", "hello", "hi" };
string userInput = Console.ReadLine();
bool result_a = greeting.Any(x=>x.StartsWith(userInput));
if (result_a) { Console.WriteLine("hey there"); }
if (result_a) { Console.WriteLine($"{greeting.FirstOrDefault(x => x.StartsWith(userInput))} there"); }

尝试这个，兄弟
List<string> greeting = new List<string>();
greeting.Add("hey");
greeting.Add("hello");
greeting.Add("hi");
string userInput = Console.ReadLine();
if (greeting.Contains(userInput.Trim()))
{
Console.WriteLine("hey there");
}
英文:
try this,bro
List<string> greeting = new List<string>();
greeting.Add("hey");
greeting.Add("hello");
greeting.Add("hi");
string userInput = Console.ReadLine();
if (greeting.Contains(userInput.Trim()))
{
Console.WriteLine("hey there");
}
