This is my first question here!
I'm working on a C# coding assignment for college where the player inputs different actions and results of their actions are displayed in the console. Until now, I have simply been saying
(if firstInput == "Action" || firstInput == "action")
I have heard that I could simplify this using string.ToLower(), but I cannot seem to figure out how to.
Any help on this would be appreciated, and my apologies if it's pretty obvious, I'm a C# noob :p
Thanks!
If it really matters if the user wrote the first letter in capital letter or not, you might need to compare the strings specifying not to ignore cases.
So, since "Action" != "action", give a try to String.Equals
bool isEqual = String.Equals(x, y, StringComparison.Ordinal);
So then, I would perform a .ToLower() from the user's input and then compare it with the original input.
The idea is to convert the input to all lower case, so that you can always compare against a lower case string constant no matter what the user entered
if (firstInput.ToLower() == "action") {
...
}
Examples:
"ACTION".ToLower() ===> "action"
"Action".ToLower() ===> "action"
"action".ToLower() ===> "action"
string.ToLower() returns a new string containing all lowercase characters. So your code should read like this:
if (firstInput.ToLower() == "action"){
{
The .ToLower() transforms firstInput into an all-lowercase string. When you compare that with an all lowercase string literal for "action", the compare will succeed if firstInput contains "action" in any upper or lower case form (Action, action, aCtIoN, etc).
It's worth noting that the Microsoft .Net documentation tells you how to use string.ToLower(). As part of learning how to program in C#, you should get used to checking the Microsoft .Net documentation to learn how to use functionality provided by the framework. The string.ToLower() article provides a complete code sample:
using System;
public class ToLowerTest {
public static void Main() {
string [] info = {"Name", "Title", "Age", "Location", "Gender"};
Console.WriteLine("The initial values in the array are:");
foreach (string s in info)
Console.WriteLine(s);
Console.WriteLine("{0}The lowercase of these values is:", Environment.NewLine);
foreach (string s in info)
Console.WriteLine(s.ToLower());
}
}
// The example displays the following output:
// The initial values in the array are:
// Name
// Title
// Age
// Location
// Gender
//
// The lowercase of these values is:
// name
// title
// age
// location
// gender
if (firstInput.ToLower() == "action")? I mean it appears a super simple and duplicate question from what you post, and code examples are always goodStringComparison.InvariantCultureIgnoreCase.
