public static byte ToByte(
	string 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).


value does not consist of an optional sign followed by a sequence of digits (0 through 9).


value represents a number that is less than Byte..::..MinValue or greater than Byte..::..MaxValue.

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.
