its like a varuable statement that will change depend on what the list is one example: int age = 18; Console.WriteLine("Your age is{0}", age); the output is Your age is 18 see the "age" word beside {0}? it means the {0} is the variable that outdepend on the indentifer so the age is inputed to {0} example int age = 18; string name = Console.ReadLine(); Console.WriteLine("Age is {0} and your name is {1}", age, name); now theres 2 {} and 2 identifer beside {1}, its "age" and "name", the "age" its inputed to {0} because its in the front, and the "name" is inputed to {1} because its in backward of the "age"

The name given to {0} is called "placeholder". It tells the argument of ReadLine() in this case that there is a variable whose value is going to get inserted or placed at the position of {0} in the string. The "0" means its the first variable, so the second will be {1} and so on.

{0} is a placeholder for your variable. eg: a = 1 console.writeline("{0}",a); if there is another variable the '0' increaments to '1' that is {1}. eg: a=1 & b=2 console.writeline("a is {0} ] and b is {1}", a, b);

in c# 6 you can use now string interpolation where if you have a name variable you can format something like below. using static System.Console; /* Static name space declaration to use the static method of the class directly with no class name*/ var name= "Asish"; var lastName="Mohapatra"; var data=
quot;hi ! my name is {name} and my last name is {lastName}; Writeline(data); Output hi ! my name is Asish and my last name is Mohapatra. Explanation Here we have used $ to indicate that we are using string interpolation. instead of using {0} or {1} now we are using exact variable. This is available only on C# 6 !!!!!
