Understand the {0}

Question

static void Main(string[] args)
{
string yourName;
Console.WriteLine("What is your name?");

yourName = Console.ReadLine();

Console.WriteLine("Hello {0}", yourName);
}

I was trying to understand this code but I can’t understand what the {0} mean? The rest of the code I think I understand.

Answer 1

It substitutes a value in its place. The 0, 1 etc. inside the curly braces refer to which string should be substituted where

Here is an example:

Console.WriteLine("{0} {1} {0}", "l", "o");

This outputs "lol"
