C# | Decimal.ToString Method | Set -1
Decimal.ToString() Method is used to convert the numeric value of the current instance to its equivalent string representation using the specified culture-specific format information. There are 4 methods in the overload list of this method as follows:
- ToString() Method
- ToString(IFormatProvider) Method
- ToString(String, IFormatProvider) Method
- ToString(String) Method
Here, we will discuss the first 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 a string which represents the value of the current instance.
Below programs illustrate the use of Decimal.ToString() Method:
Example 1:
// C# program to demonstrate the // Decimal.ToString() Method using System; class GFG { // Main Method public static void Main() { // Declaring and initializing value decimal value = 7922816251426433759354.39503305M; // using ToString() method string str = value.ToString(); // Display the value Console.WriteLine( "String value is {0}" , str); } } |
String value is 7922816251426433759354.3950330
Example 2:
// C# program to demonstrate the // Decimal.ToString() Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { // calling get() method Console.WriteLine( "Equivalent String values are:" ); get (20); get (30); get (40); get (4294967295); } // defining get() method public static void get ( decimal value) { // using ToString() method string str = value.ToString(); // Display the value Console.WriteLine( "String value is {0}" , str); } } |
Equivalent String values are: String value is 20 String value is 30 String value is 40 String value is 4294967295
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);
Here, it takes a standard or custom numeric format string.Return Value: This method returns the string representation of the value of the current instance as specified by format.
Exceptions: This method throws FormatException if format is invalid.
Example 1:
// C# program to demonstrate the // Decimal.ToString(String) Method using System; class GFG { // Main Method public static void Main() { try { // Declaring and initializing value decimal value = 16325.62m; // Declaring and initializing format string s = "E04" ; // using the method string str = value.ToString(s); // Display the value Console.WriteLine( "String value is {0}" , str); } catch (FormatException e) { Console.WriteLine( "Format is invalid." ); Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
String value is 1.6326E+004
Example 2: For FormatException
// C# program to demonstrate the // Decimal.ToString(String) Method using System; class GFG { // Main Method public static void Main() { try { // Declaring and initializing value decimal value = 16325.62m; // Declaring and initializing format string s = "a" ; // using the method string str = value.ToString(s); // Display the value Console.WriteLine( "String value is {0}" , str); } catch (FormatException e) { Console.WriteLine( "Format is invalid." ); Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
Format is invalid. Exception Thrown: System.FormatException
