csharp
- ToString(String) Method
- ToString() Method
- ToString(IFormatProvider) Method
- ToString(String, IFormatProvider) Method
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 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
// Single.ToString(String) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing value
float value = 565998.1564f;
// 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);
}
}
}
Output:
Example 2: For FormatException
String value is 5.6600E+005
// C# program to demonstrate the
// Single.ToString(String) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing value
float value = 1623325.62412f;
// 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);
}
}
}
Output:
Format is invalid. Exception Thrown: System.FormatException
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 this instance.Below programs illustrate the use of Single.ToString() Method: Example 1:
// C# program to demonstrate the
// Single.ToString() Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value
float value = 792759354.39503305f;
// using ToString() method
string res = value.ToString();
// Display the value
Console.WriteLine("String value is {0}", res);
}
}
Output:
Example 2:
String value is 7.927594E+08
// C# program to demonstrate the
// Single.ToString() Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// calling get() method
get(Single.MaxValue);
get(Single.MinValue);
get(40f);
get(424967295.5858f);
}
// defining get() method
public static void get(float value)
{
// using ToString() method
string res = value.ToString();
// Display the value
Console.WriteLine("String value is {0}", res);
}
}
Output:
Reference:
String value is 3.402823E+38 String value is -3.402823E+38 String value is 40 String value is 4.249673E+08
