Byte::Parse Method (String^)
Converts the string representation of a number to its Byte equivalent.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- s
-
Type:
System::String^
A string that contains a number to convert. The string is interpreted using the Integer style.
| Exception | Condition |
|---|---|
| ArgumentNullException | s is null. |
| FormatException | s is not of the correct format. |
| OverflowException |
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 positive or negative 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 byte value's decimal digits, only leading and trailing spaces together with a leading sign are allowed. (If the sign is present, it must be a positive sign or the method throws an OverflowException.) To explicitly define the style elements that can be present in s, use either the Byte::Parse(String^, NumberStyles) or the Byte::Parse(String^, NumberStyles, IFormatProvider^) 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 Byte::Parse(String^, NumberStyles, IFormatProvider^) method.
The following example demonstrates how to convert a string value into a byte value using the Byte::Parse(String^) method. The resulting byte value is then displayed to the console.
String^ stringToConvert = " 162"; Byte byteValue; try { byteValue = Byte::Parse(stringToConvert); Console::WriteLine("Converted '{0}' to {1}.", stringToConvert, byteValue); } catch (FormatException^) { Console::WriteLine("Unable to parse '{0}'.", stringToConvert); } catch (OverflowException^) { Console::WriteLine("'{0}' is greater than {1} or less than {2}.", stringToConvert, Byte::MaxValue, Byte::MinValue); } // The example displays the following output to the console: // Converted ' 162' to 162.
