SByte.Parse Method (String)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Converts the string representation of a number to its 8-bit signed integer equivalent.

This API is not CLS-compliant. The CLS-compliant alternative is Parse(String).

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

Syntax

'Declaration
<CLSCompliantAttribute(False)> _
Public Shared Function Parse ( _
    s As String _
) As SByte

[CLSCompliantAttribute(false)]
public static sbyte Parse(
    string s
)

Parameters

Return Value

Type: System.SByte
An 8-bit signed integer that is equivalent to the number contained in the s parameter.

Exceptions

Exception Condition
ArgumentException

s is nulla null reference (Nothing in Visual Basic).
FormatException

s does not consist of an optional sign followed by a sequence of digits (zero through nine).
OverflowException

s represents a number less than MinValue or greater than MaxValue.

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.

Element

Description

ws

Optional white space.

sign

An optional 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 with a leading positive or negative sign are allowed. To explicitly define the style elements that can be present in s, use either the Parse(String, NumberStyles) or the Parse(String, NumberStyles, IFormatProvider) method.

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

Examples

The following example demonstrates how to convert a string value into a signed byte value using the Parse method. The resulting signed byte value is then displayed to the console.
