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.
Assembly: mscorlib (in mscorlib.dll)
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.
| Exception | Condition |
|---|---|
| ArgumentNullException | s is nullptr. |
| 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 nullptr, the NumberFormatInfo for the current culture is used.
The following example parses string representations of Int16 values with the Int16::Parse(String, IFormatProvider) method.
String^ stringToConvert; Int16 number; stringToConvert = " 214 "; try { number = Int16::Parse(stringToConvert, CultureInfo::InvariantCulture); Console::WriteLine("Converted '{0}' to {1}.", stringToConvert, number); } catch (FormatException ^e) { Console::WriteLine("Unable to parse '{0}'.", stringToConvert); } catch (OverflowException ^e) { Console::WriteLine("'{0'} is out of range of the Int16 data type.", stringToConvert); } stringToConvert = " + 214"; try { number = Int16::Parse(stringToConvert, CultureInfo::InvariantCulture); Console::WriteLine("Converted '{0}' to {1}.", stringToConvert, number); } catch (FormatException ^e) { Console::WriteLine("Unable to parse '{0}'.", stringToConvert); } catch (OverflowException ^e) { Console::WriteLine("'{0'} is out of range of the Int16 data type.", stringToConvert); } stringToConvert = " +214 "; try { number = Int16::Parse(stringToConvert, CultureInfo::InvariantCulture); Console::WriteLine("Converted '{0}' to {1}.", stringToConvert, number); } catch (FormatException ^e) { Console::WriteLine("Unable to parse '{0}'.", stringToConvert); } catch (OverflowException ^e) { Console::WriteLine("'{0'} is out of range of the Int16 data type.", stringToConvert); } // The example displays the following output to the console: // Converted ' 214 ' to 214. // Unable to parse ' + 214'. // Converted ' +214 ' to 214.
