Int32.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:
- ToString(IFormatProvider) Method
- ToString(String, IFormatProvider) Method
- ToString() Method
- 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 minus sign if the value is negative, and a sequence of digits ranging from 0 to 9 with no leading zeroes.
Example:
// C# program to illustrate the // Int32.ToString() Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
Console.WriteLine( "The String values are: " );
// calling the method
result(Int32.MaxValue);
result(Int32.MinValue);
result(78006596);
result(86542626);
}
// result() method
public static void result( int p)
{
// using ToString() method
string str = p.ToString();
// Display the value
Console.WriteLine( "The Corresponding String " +
"Value is: {0}" , str);
}
} |
The String values are: The Corresponding String Value is: 2147483647 The Corresponding String Value is: -2147483648 The Corresponding String Value is: 78006596 The Corresponding String Value is: 86542626
ToString(String) Method
This method is used to convert the numeric value of the current instance to its equivalent string representation, using the specified format.
Syntax:
public string ToString (string format);
Parameters: This method takes standard or custom numeric format string.
Return Value: This method returns the string representation of the value of this instance as specified by format.
Example:
// C# program to demonstrate the // Int32.ToString(String) Method using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing value
int val = 214563;
// Declaring and initializing format
string format = "E2" ;
// using the method
string result = val.ToString(format);
// Display the result
Console.WriteLine( "The value of string is {0}" , result);
}
catch (FormatException e) {
Console.WriteLine( "Format is invalid." );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}

The value of string is 2.15E+005
