C# String - PadRight() Method

The C# PadRight() method returns a new string that left-aligns the characters of the given string by padding them with spaces or Unicode character on the right, for a specified total length. However, if the parameter totalWidth is specified less than the number of characters in the string, the method returns the reference of the existing instance. If the totalWidth is equal to the number of characters in the string, the method returns a new string identical to the instance.

Note: This method can be overloaded by passing different type of arguments to it.

Syntax

public string PadRight (int totalWidth);
public string PadRight (int totalWidth, char paddingChar);

Parameters

Return Value

Exception

Throws ArgumentOutOfRangeException, if the totalWidth is less than zero.

class MyProgram {
  static void Main(string[] args) {
    string MyStr = "Hello World";

    Console.WriteLine(MyStr.PadRight(20));
    Console.WriteLine(MyStr.PadRight(20, '#')); 

    Console.WriteLine();
    Console.WriteLine(MyStr.PadRight(5));
    Console.WriteLine(MyStr.PadRight(5, '#')); 
  }
}
