How can I display the value of a variable on the screen within a text in c#? [duplicate]

  • 772

I am making a desktop application and I want to display the value of a variable on the screen inside the quotes this is my code

 static void Main(string[] args)
    {

        int casa = 16;


        Console.WriteLine("variable {{casa}}");
        Console.ReadKey();
    }

It prints casano 16, it can be done by adding and the name of the variable but I want it inside the quotes, could it be done???

c#

    There are two ways to display the value of the variable:

    Placing the variable after the operator +, outside the""

    1) Console.WriteLine("variable" + casa);

    Or this second option is only available for C# >= 6.0 . Placing the symbol $after the start parenthesis and placing the variable name {}inside the "":

    two Console.WriteLine($"variable {casa}");

    All the best.

  2. Having several options, the two most common, would be,

    Concatenate

     static void Main(string[] args)
    {

        int casa = 16;
        Console.WriteLine("variable "+ casa);
        //Mostraría variable 16
        Console.ReadKey();
    }

    Or also, you could build a string with String.Format , but it would apply, perhaps, to more particular situations

     static void Main(string[] args)
    {

        int casa = 16;
        String texto = String.Format("La variable es {0}.",
                     casa);
        Console.WriteLine(s);
        //Mostraría La variable es 16
        Console.ReadKey();
    }

    As I said before, you have an infinite number of ways to do what you are looking for, it would be a matter of finding which one is the most comfortable for you.

    Cheers
