String Interpolation(字串內插)

Q:What is string interpolation?
A:string interpolation is a way that replaces the value with variable into string. So the string is not always same. the variable can determine it.

Q:What is the form of string interpolation?
A:dollar sign before quotation.

use dollar sign  with curly bracket. Compiler will replace it with variable.
syntax:
such as the following code.
//C#
int age=20;
string name="Jay";
//Compiler will replace {name} into variable name as Jay.
Console.WriteLine($"my name is {name}, I am {age} years old.");
/*
output:
my name is Jay, I am 20 years old."
*/

NOTE:

Please pay a lot of attention on the notice.
version which is under C# 6.0  will NOT support this way.
