This method is used to convert the specified string representation of a number to an equivalent 16-bit signed integer, using the specified culture-specific formatting information.
Syntax:
public static short ToInt16 (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 a decimal number which is equivalent to the number in value, or 0 (zero) if value is null.
Exceptions:
- 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.ToDecimal(String, IFormatProvider) Method:
Example 1:
// C# program to demonstrate the // Convert.ToInt16() 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 = { "12345" , "+12345" ,
"-12345" };
// calling get() Method
Console.Write( "Converted short 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: " );

}
} // Defining get() method public static void get ( string s,
CultureInfo cultures)
{ // converting string to specified short

} } |
Converted short value from a specified string 12345, 12345, -12345,
