Int16.Parse Method (String, IFormatProvider)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
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)
Syntax
'Declaration
Public Shared Function Parse ( _
s As String, _
provider As IFormatProvider _
) As Short
public static short Parse(
string s,
IFormatProvider provider
)
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.
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
This overload of the Parse(String, IFormatProvider) method is typically used to convert text that can be formatted in a variety of ways to an Int16 value.
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 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 nulla null reference (Nothing in Visual Basic), the NumberFormatInfo for the current culture is used.
Examples
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)
outputBlock.Text += String.Format("Converted '{0}' to {1}.", stringToConvert, number) + vbCrLf
Catch e As FormatException
outputBlock.Text += String.Format("Unable to parse '{0}'.", stringToConvert) + vbCrLf
Catch e As OverflowException
outputBlock.Text += String.Format("'{0'} is out of range of the Int16 data type.", _
stringToConvert) + vbCrLf
End Try
stringToConvert = " + 214"
Try
number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture)
outputBlock.Text += String.Format("Converted '{0}' to {1}.", stringToConvert, number) + vbCrLf
Catch e As FormatException
outputBlock.Text += String.Format("Unable to parse '{0}'.", stringToConvert) + vbCrLf
Catch e As OverflowException
outputBlock.Text += String.Format("'{0'} is out of range of the Int16 data type.", _
stringToConvert) + vbCrLf
End Try
stringToConvert = " +214 "
Try
number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture)
outputBlock.Text += String.Format("Converted '{0}' to {1}.", stringToConvert, number) + vbCrLf
Catch e As FormatException
outputBlock.Text += String.Format("Unable to parse '{0}'.", stringToConvert) + vbCrLf
Catch e As OverflowException
outputBlock.Text += String.Format("'{0'} is out of range of the Int16 data type.", _
stringToConvert) + vbCrLf
End Try
' The example displays the following output to the console:
' Converted ' 214 ' to 214.

string stringToConvert;
short number;
stringToConvert = " 214 ";
try
{
number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture);
outputBlock.Text += String.Format("Converted '{0}' to {1}.\n", stringToConvert, number);
}
catch (FormatException)
{
outputBlock.Text += String.Format("Unable to parse '{0}'.\n", stringToConvert);
}
catch (OverflowException)
{
outputBlock.Text += String.Format("'{0'} is out of range of the Int16 data type.\n",
stringToConvert);
}
stringToConvert = " + 214";
try
{
number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture);
outputBlock.Text += String.Format("Converted '{0}' to {1}.\n", stringToConvert, number);
}
catch (FormatException)
{
outputBlock.Text += String.Format("Unable to parse '{0}'.\n", stringToConvert);
}
catch (OverflowException)
{
outputBlock.Text += String.Format("'{0'} is out of range of the Int16 data type.\n",
stringToConvert);
}
stringToConvert = " +214 ";
try
{
number = Int16.Parse(stringToConvert, CultureInfo.InvariantCulture);
outputBlock.Text += String.Format("Converted '{0}' to {1}.\n", stringToConvert, number);
}
catch (FormatException)
{
outputBlock.Text += String.Format("Unable to parse '{0}'.\n", stringToConvert);
}
catch (OverflowException)
{
outputBlock.Text += String.Format("'{0'} is out of range of the Int16 data type.\n",
stringToConvert);
}
// The example displays the following output to the console:
// Converted ' 214 ' to 214.
// Unable to parse ' + 214'.
// Converted ' +214 ' to 214.
