C#: How to use return from a different class

Question

Since I'm a total beginner I don't know much about C# yet.
I want to use the returned string from Method 1 in my main method.
Shouldn't I be able to use it since Method1 is public?

public string Method1() { Console.Write("Vorname: "); string vorname = Convert.ToString(Console.ReadLine()); Console.Write("Nachname: "); string nachname = Convert.ToString(Console.ReadLine()); Console.Write("Adresse: "); string adresse = Convert.ToString(Console.ReadLine()); string info = vorname + nachname + adresse; return (info); } static void Main(string[] args) { string dateipfad = @"C:\Users\kaihe\Documents\persönliche_informationen.txt"; AllMethods txtfileabfrage = new AllMethods(); txtfileabfrage.Method2(); AllMethods input = new AllMethods(); Console.WriteLine(info); File.WriteAllText(dateipfad, info); Console.ReadKey(); }

Method1 needs to be static if you want to call it from a static method. And the Convert.ToString is unnecessary because Console.ReadLine returns a string already. — ArgusMagnus

Method1 should also be static since you are calling from Main which is static.

If you add the static keyword to Method1() you will be able to call Method1() from the main method.

 static void Main(string[] args) { String returnedValue = Method1(); } public static string Method1() { Console.Write("Vorname: "); string vorname = Convert.ToString(Console.ReadLine()); Console.Write("Nachname: "); string nachname = Convert.ToString(Console.ReadLine()); Console.Write("Adresse: "); string adresse = Convert.ToString(Console.ReadLine()); string info = vorname + nachname + adresse; return (info); }

You need to save the returned value to a variable otherwise it cannot be used.
Well actually there is no need to store the returned value. You could use it like so: Console.WriteLine(Method1());
If you look at OP's original code - you will see that "info" (presumably the expected returned value) is used twice - so storing in a variable IS required (calling method1 twice would result in requiring the data to be input twice).
Yes I agree that OP wants to store the output of his method however it is still untrue that "You need to save the returned value to a variable otherwise it cannot be used".
