C# Formatted String

In C#, formatted strings can be created using the String.Format method or interpolated strings. Here are examples of both approaches:

Using `String.Format` Method

string name = "John";
int age = 30;
string formattedString = string.Format("The person's name is {0} and their age is {1}.", name, age);
Console.WriteLine(formattedString);

In the above example, {0} and {1} are placeholders for the name and age variables respectively.

Interpolated Strings

string name = "Emily";
int age = 25;
string interpolatedString = $"The person's name is {name} and their age is {age}.";
Console.WriteLine(interpolatedString);

In the interpolated string, the variables name and age are directly embedded within the string using the $ symbol.

using System;

class Program
{
    static void Main()
    {
        // Using interpolated strings
        string name = "Jane";
        string dayOfWeek = DateTime.Now.DayOfWeek.ToString();

        string formattedString = $"Hello, {name}! Today is {dayOfWeek}.";

        Console.WriteLine(formattedString);
    }
}
