String

A string is a sequence of characters. Strings are used for storing textual data.

main


              1234567891011121314
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			string text = "Hello, World!";
			Console.WriteLine(text); // Output: Hello, World!
        }
    }
}

String data (text) is always enclosed in double quotation marks (").

We of course cannot perform arithmetic operations on strings however we can use the plus (+) operator to join two strings. The process of joining strings using the plus operator is called string concatenation.

main


              123456789101112131415
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			string partOne = "The first sentence. ";
			string partTwo = "The second sentence.";
			string combined = partOne + partTwo;
			Console.WriteLine(combined); // Output: The first sentence. The second sentence.
        }
    }
}

We can use the new line character (\n) to represent a new line in string data.

For-example:

main


              12345678910111213
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			string text = "The first line.\nThe second line.";
			Console.WriteLine(text);
        }
    }
}

When the \n character is encountered, the text automatically shifts to a new line. We can use multiple newline characters to skip multiple lines:

main


              12345678910111213
            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			string text = "The first line.\n\n\nThe second line.\nThe third line.";
			Console.WriteLine(text);
        }
    }
}

Tudo estava claro?
