Single.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(String) Method
- ToString() Method
- ToString(IFormatProvider) Method
- ToString(String, IFormatProvider) Method
Here, we will discuss the first two methods.
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:
using System;
class GFG {
public static void Main()
{
try {
float value = 565998.1564f;
string s = "E04" ;
string str = value.ToString(s);
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:
String value is 5.6600E+005
Example 2: For FormatException
using System;
class GFG {
public static void Main()
{
try {
float value = 1623325.62412f;
string s = "a" ;
string str = value.ToString(s);
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:
using System;
class GFG {
public static void Main()
{
float value = 792759354.39503305f;
string res = value.ToString();
Console.WriteLine( "String value is {0}" , res);
}
}
|
Output:
String value is 7.927594E+08
Example 2:
using System;
using System.Globalization;
class GFG {
public static void Main()
{
get (Single.MaxValue);
get (Single.MinValue);
get (40f);
get (424967295.5858f);
}
public static void get ( float value)
{
string res = value.ToString();
Console.WriteLine( "String value is {0}" , res);
}
}
|
Output:
String value is 3.402823E+38
String value is -3.402823E+38
String value is 40
String value is 4.249673E+08
