C# Strings

To represent a sequence of characters, strings are used in C#. It is an object of System.String class. Several operations like concatenation, comparison, getting substring, search, trim, replacement etc, can be performed on C# strings.

Comparison between string and String:

The string is an alias for System.String class. It is a keyword in C# which is equivalent to String. Any naming convention can thus be used for a string in C#.

Example: To create a string using the string keyword:

string s1 = "keyword";

Example: To create a string using the String class:

String s2 = "class";

Example:

using System;  
public class Example  
{  
    public static void Main(string[] args)  
    {  
        string str1 = "String1";  
 
        char[] ch1 = { 'S', 't', 'r', 'i', 'n', 'g', '2' };  
        string str2 = new string(ch1);  
 
        Console.WriteLine(str1);  
        Console.WriteLine(str2);  
    }  
}

Explanation:

In the above example, we are creating two strings in C# using the string keyword. Both the strings will be displayed on the console screen as output.
