Byte.Parse Method (String)
Converts the string representation of a number to its Byte equivalent.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- s
-
Type:
System.String
A string that contains a number to convert. The string is interpreted using the Integer style.
| Exception | Condition |
|---|---|
| ArgumentNullException | s is null. |
| FormatException | s is not of the correct format. |
| OverflowException |
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.
The following example demonstrates how to convert a string value into a byte value using the Byte.Parse(String) method. The resulting byte value is then displayed to the console.
Dim stringToConvert As String = " 162" Dim byteValue As Byte Try byteValue = Byte.Parse(stringToConvert) Console.WriteLine("Converted '{0}' to {1}.", stringToConvert, byteValue) Catch e As FormatException Console.WriteLine("Unable to parse '{0}'.", stringToConvert) Catch e As OverflowException Console.WriteLine("'{0}' is greater than {1} or less than {2}.", _ stringToConvert, Byte.MaxValue, Byte.MinValue) End Try ' The example displays the following output to the console: ' Converted ' 162' to 162.
