如何检查输入是否等于字符串

Question

I am trying to make a friendly ai, but I need to be able to detect if the input is equal to a string. I tried a lot of things, but none of them worked.

Here is my code so far... ;)

namespace Game
{
    public static class Program
    {
        public static string name;
        public static string enteredCommand;
        public static int commanddomath = 1;
        static void Main()
        {
            Console.Title = "Phil";
            Console.ForegroundColor = ConsoleColor.Green;

            Console.WriteLine("                           ");
            Console.WriteLine("             / /        / /");
            Console.WriteLine("             |@|        |@|");
            Console.WriteLine("                --_____--  ");
            Console.WriteLine("                 //////    ");
            Console.WriteLine("                           ");
            

            Console.WriteLine("Hello, my name is Phil");

            Console.WriteLine("What is your name");

            name = Console.ReadLine();
            Console.WriteLine("Hello, " + name);
           //  Console.WriteLine("What do you want me to do?");
           //  enteredCommand = Console.ReadLine();

           // if (enteredCommand = 1)
           // {

           // }

            Console.ReadKey();
        }
    }
}

Thanks for any help :)

Answer 1

if(enteredCommand == "1")

由于Console.ReadLine返回一个字符串，您还需要将其与字符串进行比较，而不是整数

Answer 2

I suggest you to stick to

string.Equals(string1, string2);

for comparing strings in the future, since it is less type strict . (ie you can compare object obj = "string" and string str = "string" using .Equals and you will get true , while using "==" the result will be false .

PS. Don't use it when type safety is necessary.

It also accepts

System.StringComparison.OrdinalIgnoreCase

Which ignores casing for strings/objects.

if (string.Equals(enteredCommand, "1")) 
{
  //do something
}
