System.Byte.Parse Method

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

Syntax

public static byte Parse (string s)

Parameters

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

Returns

A byte value that is equivalent to the number contained in s.

Exceptions

TypeReason
ArgumentNullException s is a null reference.
FormatException s is not in the correct style.
OverflowException s represents a number greater than byte.MaxValue or less than byte.MinValue.

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.

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 System.Globalization.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, System.Globalization.NumberStyles) or the byte.Parse(string, System.Globalization.NumberStyles, IFormatProvider) method.

The s parameter is parsed using the formatting information in a System.Globalization.NumberFormatInfo object that is initialized for the current system culture. For more information, see System.Globalization.NumberFormatInfo.CurrentInfo. To parse a string using the formatting information of some other culture, use the byte.Parse(string, System.Globalization.NumberStyles, IFormatProvider) method.

Example

The following example demonstrates the byte.Parse(string) method.

C# Example

using System;
public class ByteParseClass {
public static void Main() {
   string str = "  100   ";
   Console.WriteLine("String: \"{0}\" <Byte> {1}",str,Byte.Parse(str));
}
}
   

The output is

String: " 100 " <Byte> 100
