How can i write a variabile in the Function Console.Write in this case?

I am learning c# for fun! I have experience with the c coding and I have a really stupid question, in my console application, I want to show a variable called "x" using Console.Write but I want to show it with also a text line in the same function. If you don't understand I attach here the code that i did.

  using System;

namespace Media_Random
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            Console.Write ("This program makes an avarage of 3 numbers chosen randomly\n");
            int a = 1;
            int b = 10;
            Random random = new Random();
            int x=random.Next(a,b);
            Console.Write ("the first value is\n",x); //i want to in write in the console the value x there but it doesn't work 
        }
    }

}

I hope that showing the code it will be more simple to understand the problem.

One more thing. If you are using VS 2015 you can change string.Format with $ like this:

Console.WriteLine($"the first value is {x}");

Adding $ in front of the open quotes allows you to put the variables inside the placeholders directly. From my point of view this syntax is much more easier and more readable.

Try this:

 Console.Write("the first value is {0}\n", x);

Please, notice that the overloaded Console.Write you've used wants format string with placeholder for x: {0} in the context.

Further suggestion: Console has as special method WriteLine that's why you, probably, don't want put

 Console.Write("...\n");

instead of

 Console.WriteLine("...");

If you want to do this to display it in this format :

the first value is
X

Then use this method :

Console.Write(string.Format("the first value is\n{0}", x));

But if you prefer to display int in this format :

the first value is X
<newlinehere>

Then use this method :

Console.WriteLine(string.Format("the first value is {0}\n', x));

You should read this if you want to format it in the different way.
