$ sign in c#

Question

Console.WriteLine(

Answer 1

It's the new feature in C# 6 it is called Interpolated Strings.

The dollar tells the compiler. This string contains placeholders so instead of writing

Console.WriteLine("\n\tYour result is {0}.", result);

You can write now the variable is inline and the code it better readable.

Console.WriteLine(quot;\n\tYour result is {result}.");

Answer 2

now ı know we don not use special place holders but use it directly like
string str ="name";

Console.WriteLine(quot;hello! ,{str}");
in curly braces inside the string

I extended my place holder experiment.

Console.WriteLine(String.Format("counting from 1 to 5 {0}{1}{2}{3}{4}", a,b,c,d,e));
Console.WriteLine(String.Format(quot;counting from 1 to 5 {a}{b}{c}{d}{e}"));

are the same.
