Can someone tell me how can I know the numbers of characters in a string entered by the user in C# code?Like if i take a string from the user and he writes "CODE" so it has 4 characters. So how can i know ?

What I have tried:

I just google because I don't know anything about it as I was dealing strings with arrays and there only codes are available for strings not taken by the user.

Use the Length property of the string class:

A string is a string, is a string: it doesn't matter where is came from - the user via a Console.ReadLine, a textbox.Text property, a Combobox.Value, or a static constant you typed before your app compiled.
In you app it's an instance of a string, that's all - so all the string properties and methods are available to you: String Class (System) | Microsoft Docs[^]
That includes the string.Length property:

C#

string read = Console.ReadLine();
string typed = MyTextBox.Text;
string compiled = "CODE";
Console.WriteLine($"{read.Length}:{typed.Length}:{compiled.Length}");
