Byte.Parse Method (String, IFormatProvider)

Converts the string representation of a number in a specified culture-specific format to its Byte equivalent.

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

public static byte Parse(
	string s,
	IFormatProvider provider
)

Parameters

s
Type: System.String

A string that contains a number to convert. The string is interpreted using the Integer style.

provider
Type: System.IFormatProvider

An object that supplies culture-specific parsing information about s. If provider is null, the thread current culture is used.

Return Value

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

ExceptionCondition
ArgumentNullException

s is null.

FormatException

s is not of 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

Optional white space.

sign

An optional positive sign.

digits

A sequence of digits ranging from 0 to 9.

The s parameter is interpreted using the 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 together with the culture-specific formatting information that can be present in s, use the Byte.Parse(String, NumberStyles, IFormatProvider) method.

The s parameter is parsed using the formatting information in a NumberFormatInfo object supplied by provider. The provider parameter is an IFormatProvider implementation such as a NumberFormatInfo or CultureInfo object. The provider parameter supplies culture-specific information used in parsing. If provider is null, the thread current culture is used.

The following example parses string representations of Byte values with the Parse method.

string stringToConvert; 
byte byteValue;

stringToConvert = " 214 ";
try {
   byteValue = Byte.Parse(stringToConvert, CultureInfo.InvariantCulture);
   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); }

stringToConvert = " + 214 ";
try {
   byteValue = Byte.Parse(stringToConvert, CultureInfo.InvariantCulture);
   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); }

stringToConvert = " +214 ";
try {
   byteValue = Byte.Parse(stringToConvert, CultureInfo.InvariantCulture);
   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 ' 214 ' to 214. 
//       Unable to parse ' + 214 '. 
//       Converted ' +214 ' to 214.
