ToByte Method

2013-01-16

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Converts the specified string representation of a number to an equivalent 8-bit unsigned integer.

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

Syntax

'Declaration
Public Shared Function ToByte ( _
    value As String _
) As Byte

public static byte ToByte(
    string value
)

public:
static unsigned char ToByte(
    String^ value
)

static member ToByte : 
        value:string -> byte

public static function ToByte(
    value : String
) : byte

Parameters

value
Type: System. . :: . .String
A string that contains the number to convert.

Return Value

Type: System. . :: . .Byte
An 8-bit unsigned integer that is equivalent to value, or zero if value is nullNothingnullptrunita null reference (Nothing in Visual Basic).

Exceptions

Exception	Condition
FormatException	value does not consist of an optional sign followed by a sequence of digits (0 through 9).
OverflowException	value represents a number that is less than Byte..::..MinValue or greater than Byte..::..MaxValue.

Remarks

Using the ToByte(String) method is equivalent to passing value to the Byte..::..Parse(String) method. value is interpreted by using the formatting conventions of the current thread culture.

If you prefer not to handle an exception if the conversion fails, you can call the Byte.TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.
