Int16.Parse Method (String)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts the string representation of a number to its 16-bit signed integer equivalent.

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

Syntax

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

public static short Parse(
    string s
)

Parameters

Return Value

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

Exceptions

Exception Condition
ArgumentNullException

s is nulla null reference (Nothing in Visual Basic).
FormatException

s is not in the correct format.
OverflowException

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

Remarks

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

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 the integer value's decimal digits, only leading and trailing spaces together with a leading sign are allowed. To explicitly define the style elements that can be present in s, use either the Int16.Parse(String, NumberStyles) or the Parse method.

The s parameter is parsed using the formatting information in a NumberFormatInfo object that is initialized for the current system culture. For more information, see CurrentInfo. To parse a string using the formatting information of some other culture, use the Int16.Parse(String, NumberStyles, IFormatProvider) method.

Examples

The following example demonstrates how to convert a string value into a 16-bit signed integer value using the Int16.Parse(String) method. The resulting integer value is then displayed to the console.

Dim value As String
Dim number As Short

value = " 12603 "
Try
   number = Short.Parse(value)
   outputBlock.Text += String.Format("Converted '{0}' to {1}.", value, number) & vbCrLf
Catch e As FormatException
   outputBlock.Text += String.Format("Unable to convert '{0}' to a 16-bit signed integer.", _
                     value) & vbCrLf
End Try

value = " 16,054"
Try
   number = Short.Parse(value)
   outputBlock.Text += String.Format("Converted '{0}' to {1}.", value, number) & vbCrLf
Catch e As FormatException
   outputBlock.Text += String.Format("Unable to convert '{0}' to a 16-bit signed integer.", _
                     value) & vbCrLf
End Try

value = " -17264"
Try
   number = Short.Parse(value)
   outputBlock.Text += String.Format("Converted '{0}' to {1}.", value, number) & vbCrLf
Catch e As FormatException
   outputBlock.Text += String.Format("Unable to convert '{0}' to a 16-bit signed integer.", _
                     value) & vbCrLf
End Try
' The example displays the following output:
'       Converted ' 12603 ' to 12603.

'       Converted ' -17264' to -17264.      

string value;
short number;

value = " 12603 ";
try
{
   number = Int16.Parse(value);
   outputBlock.Text += String.Format("Converted '{0}' to {1}.", value, number) + "\n";
}
catch (FormatException)
{
   outputBlock.Text += String.Format("Unable to convert '{0}' to a 16-bit signed integer.",
                     value) + "\n";
}

value = " 16,054";
try
{
   number = Int16.Parse(value);
   outputBlock.Text += String.Format("Converted '{0}' to {1}.", value, number) + "\n";
}
