UInt32.ToString Method in C# with Examples | Set – 2

UInt32.ToString Method is used to convert the numeric value of the current instance to its equivalent string representation. There are 4 methods in the overload list of this method as follows:

  1. ToString(IFormatProvider) Method
  2. ToString(String, IFormatProvider) Method
  3. ToString() Method
  4. ToString(String) Method

Here, we will discuss the last two methods.

ToString() Method

This method is used to convert the numeric value of the current instance to its equivalent string representation.

Syntax:

public override string ToString ();

Return Value: This method returns the string representation of the value of the current instance, consisting of a sequence of digits ranging from 0 to 9, without a sign or leading zeroes.

using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        Console.WriteLine("The String values are: ");
  
        // calling the method
        result(UInt32.MaxValue);
        result(UInt32.MinValue);
        result(155156);
        result(199947);
    }
  
    // result() method
    public static void result(uint p)
    {
  
        // using ToString() method
        string str = p.ToString();
  
        // Display the value
        Console.WriteLine("The Corresponding String "
                             + "Value is: {0}", str);
                            
    }
}

Output:

The String values are: 
The Corresponding String Value is: 4294967295
The Corresponding String Value is: 0
The Corresponding String Value is: 155156
The Corresponding String Value is: 199947

ToString(String) Method

        }
  
        catch (FormatException e) 
        {
            Console.WriteLine("Format is invalid.");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
