In this post we will learn about “String Interpolation in C#”. It is a technique of combining, formatting, and manipulating strings. This functionality was introduced in C# 6 version. By employing string interpolation, we can incorporate objects and expressions into the string interpolation process.
Important point is format of string interpolation begins with a ‘$’ symbol and expressions or string variables are enclosed within a brace {} using the subsequent format.
Syntax
{<interpolatedExpression>[,<alignment>][:<formatString>]}Details of above Syntax
- InterpolatedExpression: It is the expression that produces a formatted result.
- Alignment: This value defines the minimum number of characters in the string representation of the result. If it is positive, then string representation is right-aligned and if negative, it will be left-aligned.
- FormatString: It is a format string that is supported by the type of the expression result.
Interpolation Sample Code
static void Main(string[] args)
{
string name = "Code config";
string finalValue = $"Welcome to {name} !";
Console.WriteLine(finalValue);
Console.ReadLine();
}Output
One more example of Interpolation is given below.
static void Main(string[] args)
{
string name = "Mukesh Kumar";
string expertise = "Asp.net Core";
int year = 2023;
string hello = $"Name of student is {name}. \n" +
$"His is expert in {expertise } & current year is {year}. ";
Console.WriteLine(hello);
Console.ReadLine();
}Output:
String Interpolation in C# with “FormatString“
static void Main(string[] args)
{
DateTime date = new DateTime();
date = DateTime.Now;
Console.WriteLine($"Today's date is {date:dddd, MMMM dd, yyyy} ");
Console.ReadLine();
}
