Int16.Parse Method (String, IFormatProvider)

Converts the string representation of a number in a specified culture-specific format to its 16-bit signed integer equivalent.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Shared Function Parse ( _
	s As String, _
	provider As IFormatProvider _
) As Short

Parameters

s
Type: System.String

A string containing a number to convert.

provider
Type: System.IFormatProvider

An IFormatProvider that supplies culture-specific formatting information about s.

Return Value

Type: System.Int16
A 16-bit signed integer equivalent to the number specified in s.

ExceptionCondition
ArgumentNullException

s is Nothing.

FormatException

s is not in the correct format.

OverflowException

s represents a number less than MinValue or greater than MaxValue.

The s parameter contains a number of the form:

[ws][sign]digits[ws]

Elements in square brackets ([ and ]) are optional. The following table describes each element.

Element

Description

ws

An optional white space.

sign

An optional sign.

digits

A sequence of digits ranging from 0 to 9.

The s parameter is interpreted using the NumberStyles.Integer style. In addition to decimal digits, only leading and trailing spaces together with a leading sign are allowed in s. To explicitly define the style elements together with the culture-specific formatting information that can be present in s, use the Int16.Parse(String, NumberStyles, IFormatProvider) method.

The provider parameter is an IFormatProvider implementation that obtains a NumberFormatInfo object. The NumberFormatInfo provides culture-specific information about the format of s. If provider is Nothing, the NumberFormatInfo for the current culture is used.

The following example parses string representations of Int16 values with the Int16.Parse(String, IFormatProvider) method.

Dim stringToConvert As String 
Dim number As Short

stringToConvert = " 214 " 
Try
   number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture)
   Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, number)
Catch e As FormatException
   Console.WriteLine("Unable to parse '{0}'.", stringToConvert)
Catch e As OverflowException
   Console.WriteLine("'{0'} is out of range of the Int16 data type.", _
                     stringToConvert)
End Try

stringToConvert = " + 214"                                  
Try
   number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture)
   Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, number)
Catch e As FormatException
   Console.WriteLine("Unable to parse '{0}'.", stringToConvert)
Catch e As OverflowException
   Console.WriteLine("'{0'} is out of range of the Int16 data type.", _
                     stringToConvert)
End Try

stringToConvert = " +214 "  
Try
   number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture)
   Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, number)
Catch e As FormatException
   Console.WriteLine("Unable to parse '{0}'.", stringToConvert)
Catch e As OverflowException
   Console.WriteLine("'{0'} is out of range of the Int16 data type.", _
                     stringToConvert)
End Try 
' The example displays the following output to the console: 
'       Converted ' 214 ' to 214. 
'       Unable to parse ' + 214'. 
'       Converted ' +214 ' to 214.
