There are Several Methods Present in the C# String Class. In This Tutorial, We Will Discuss Some of The Most Commonly Used String Methods in C#:<\/strong><\/p>\n

In C#, the string is represented as a sequence of characters. It is an object of System.String class. C# allows the users to perform different operations on a string such as a substring, trim, concatenate, etc.<\/p>\n

The string can be declared by using the keyword string<\/strong> which is an alias for the System.String object.<\/p>\n

Difference Between String And string?<\/h2>\n

This question has been revolving around in the minds of many beginners. In C# the \u201cstring\u201d keyword is a reference to System.String class. This makes both string and String equal. Hence, you are free to use any naming convention you prefer.<\/p>\n

string a = \u201chello\u201d; \/\/ defining the variable using \u201cstring\u201d keyword\r\nString b = \u201cWorld\u201d; \/\/defining the variable using \u201cString\u201d class\r\nConsole.WriteLine(a+ \u201c \u201c+b);<\/pre>\n
The output will be:<\/strong><\/p>\n
hello World<\/p>\n
C# String Methods<\/h2>\n
There are several methods present in the String class. These methods help in working with different string objects. In this tutorial, we will be discussing some of the most commonly used methods.<\/p>\n
#1) Clone( )<\/span><\/h3>\n
The clone method in C# is used to duplicate a string type object. It returns a clone of the same data as the object type.<\/p>\n
Parameter and Return Type<\/strong><\/p>\n
The clone method does not accept any parameters but returns an object.<\/p>\n
Clone method example<\/strong><\/span><\/p>\n
String a = \"hello\";\r\nString b = (String)a.Clone();\r\nConsole.WriteLine(b);<\/pre>\n
Output<\/strong><\/p>\n
hello<\/p>\n
Explanation<\/strong><\/p>\n
We used the Clone method to create a clone of the first string. But the clone method returns an object and an object cannot be implicitly converted into a string. Hence, we have used casting to handle this. Then we have stored it into another variable and printed it to the console.<\/p>\n
#2) Concat( )<\/span><\/h3>\n
A concat method in C# helps combine or concatenate several strings. It returns a combined string. There are several overload methods for Concat and one can use any of these based on the logical requirement.<\/p>\n
 Some of the commonly used overload methods include:<\/strong><\/p>\n
