Converts the string representation of a number to its Byte equivalent.

This API is not CLS-compliant.

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

Syntax

'Declaration
<CLSCompliantAttribute(False)> _
Public Shared Function Parse ( _
    s As String _
) As Byte

[CLSCompliantAttribute(false)]
public static byte Parse(
    string s
)

[CLSCompliantAttribute(false)]
public:
static unsigned char Parse(
    String^ s
)

[<CLSCompliantAttribute(false)>]
static member Parse : 
        s:string -> byte

public static function Parse(
    s : String
) : byte

Parameters

s
Type: System. . :: . .String
A string that contains a number to convert. The string is interpreted using the Integer style.

Return Value

Type: System. . :: . .Byte
A byte value that is equivalent to the number contained in s.

Exceptions

Exception	Condition
ArgumentNullException	s is null Nothing nullptr unit a null reference (Nothing in Visual Basic) .
FormatException	s is not of 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 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.
