Format dates in strings C# with Example

var date = new DateTime(2015, 11, 11); 
var str = $"It's {date:MMMM d, yyyy}, make a wish!"; 
System.Console.WriteLine(str); 
You can also use the DateTime.ToString method to format the DateTime object. This will produce the same output 
as the code above. 
var date = new DateTime(2015, 11, 11); 
var str = date.ToString("MMMM d, yyyy"); 
str = "It's " + str + ", make a wish!"; 
Console.WriteLine(str); 
Output: 
It's November 11, 2015, make a wish!
