string interpolation

Embeds expressions directly in string literals using the $ prefix. Cleaner alternative to string.Format().

Syntax

csharp

$"text {expression} text"

Example

csharp

string name = "Alice";
int age = 28;
string msg = $"Hello, {name}! You are {age} years old.";

double price = 9.99;
string formatted = $"Price: {price:C2}"; // "$9.99"

string multi = $"Full name: {user.FirstName} {user.LastName}";
