This method is used to convert the specified string representation of a number to an equivalent 8-bit signed integer, using the specified culture-specific formatting information.
Syntax:
public static sbyte ToSByte (string value, IFormatProvider provider);
Parameters:
- value: It is a string that contains the number to convert.
- provider: It is an object that supplies culture-specific formatting information.
Return Value: This method returns an 8-bit signed integer that is equivalent to value.
Exceptions:
- ArgumentNullException: If the value is null.
- FormatException: If the value does not consist of an optional sign followed by a sequence of digits (0 through 9).
- OverFlowException: If the value represents a number that is less than MinValue or greater than MaxValue.
Below programs illustrate the use of Convert.ToSByte(String, IFormatProvider) Method:
Example 1:
// C# program to demonstrate the // Convert.ToSByte() Method using System;
using System.Globalization;
class GFG {
// Main Method public static void Main()
{ try {
// creating object of CultureInfo
CultureInfo cultures = new CultureInfo( "en-US" );
// declaring and initializing String array
string [] values = { "123" , "+123" , "-123" };
// calling get() Method
Console.Write( "Converted sbyte value"
+ " from a specified string: " );
for ( int j = 0; j < values.Length; j++)
{
get (values[j], cultures);
}
}
catch (FormatException e)
{
Console.WriteLine( "\n" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (OverflowException e)
{
Console.WriteLine( "\n" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
} // Defining get() method public static void get ( string s,
CultureInfo cultures)
{ // converting string to specified sbyte
sbyte val = Convert.ToSByte(s, cultures);
// display the converted sbyte value
Console.Write( " {0}, " , val);
} } |
Output:
Converted sbyte value from a specified string: 123, 123, -123,
Example 2: For FormatException
// C# program to demonstrate the // Convert.ToSByte() Method using System;
using System.Globalization;
class GFG {
// Main Method public static void Main()
{ try {
// creating object of CultureInfo
CultureInfo cultures = new CultureInfo( "en-US" );
// declaring and initializing String array
string [] values = { "123" , "+123" , "-123" };
// calling get() Method
Console.Write( "Converted sbyte value"
+ " of specified strings: " );
for ( int j = 0; j < values.Length; j++)
{
get (values[j], cultures);
}
Console.WriteLine( "\n" );
string s = "123 456, 789" ;
Console.WriteLine( "format of s is invalid" );
// converting string to specified sbyte
sbyte val = Convert.ToSByte(s, cultures);
// display the converted ToSByte value
Console.Write( " {0}, " , val);
}
catch (FormatException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (OverflowException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
} // Defining get() method public static void get ( string s,
CultureInfo cultures)
{ // converting string to
// specified sbyte value
sbyte val = Convert.ToSByte(s, cultures);
// display the converted
// sbyte value
Console.Write( " {0}, " , val);
} } |
Output:
Converted sbyte value of specified strings: 123, 123, -123, format of s is invalid Exception Thrown: System.FormatException
Example 3: For OverflowException
// C# program to demonstrate the // Convert.ToSByte() Method using System;
using System.Globalization;
class GFG {
// Main Method public static void Main()
{ try {
// creating object of CultureInfo
CultureInfo cultures = new CultureInfo( "en-US" );
// declaring and initializing String array
string [] values = { "123" , "+123" , "-123" };
// calling get() Method
Console.Write( "Converted sbyte value "
+ "of specified strings: " );
for ( int j = 0; j < values.Length; j++)
{
get (values[j], cultures);
}
Console.WriteLine( "\n" );
string s = "-7922816251426433759354395033500000" ;
Console.WriteLine( "s is less than the MinValue" );
// converting string to specified sbyte
sbyte val = Convert.ToSByte(s, cultures);
// display the converted sbyte value
Console.Write( " {0}, " , val);
}
catch (FormatException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (OverflowException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
} // Defining get() method public static void get ( string s,
CultureInfo cultures)
{ // converting string to
// specified sbyte value
sbyte val = Convert.ToSByte(s, cultures);
// display the converted sbyte value
Console.Write( " {0}, " , val);
} } |
Output:
Converted sbyte value of specified strings: 123, 123, -123, s is less than the MinValue Exception Thrown: System.OverflowException
