SByte.Parse Method (String, NumberStyles)

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

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

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

[CLSCompliantAttribute(false)] 
public static sbyte Parse (
	string s,
	NumberStyles style
)
/** @attribute CLSCompliantAttribute(false) */ 
public static SByte Parse (
	String s, 
	NumberStyles style
)
CLSCompliantAttribute(false) 
public static function Parse (
	s : String, 
	style : NumberStyles
) : sbyte
Not applicable.

Parameters

s

A string containing a number to convert.

style

A bitwise combination of NumberStyles values that indicates the permitted format of s. A typical value to specify is Integer.

Return Value

An 8-bit signed integer equivalent to the number specified in s.

Exception typeCondition

ArgumentNullException

s is a null reference (Nothing in Visual Basic).

FormatException

s is not in a format compliant with style.

OverflowException

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

ArgumentException

style is not a NumberStyles value.

-or-

style is not a combination of AllowHexSpecifier and HexNumber values.

The s parameter contains a number of the form:

[ws][sign]digits[ws]

Or, if style includes AllowHexSpecifier:

[ws]hexdigits[ws]

Items in square brackets ([ and ]) are optional, and other items are as follows.

ws

Optional white space if permitted by style.

sign

An optional sign.

digits

A sequence of digits from 0 through 9.

hexdigits

A sequence of hexadecimal digits from 0 through f, or 0 through F.

The following sample demonstrates the Parse method.

SByte val;
string input;

input = " 20";
val = SByte.Parse(input);
Console.WriteLine("{0} parsed as {1}", input, val);

input = " 20";
val = SByte.Parse(input, System.Globalization.NumberStyles.HexNumber);
Console.WriteLine("{0} parsed as {1}", input, val);

input = "-120";
val = SByte.Parse(input);
Console.WriteLine("{0} parsed as {1}", input, val);

SByte val;
String input;

input = " 20";
val = (SByte)SByte.Parse(input);
Console.WriteLine("{0} parsed as {1}", input, val);

input = " 20";
val = (SByte)SByte.Parse(input, 
    System.Globalization.NumberStyles.HexNumber);
Console.WriteLine("{0} parsed as {1}", input, val);

input = "-120";
val = (SByte)SByte.Parse(input);
Console.WriteLine("{0} parsed as {1}", input, val);

var val : SByte;
var input : String;

input = " 20";
val = SByte.Parse(input);
Console.WriteLine("{0} parsed as {1}", input, val);

input = " 20";
val = SByte.Parse(input, System.Globalization.NumberStyles.HexNumber);
Console.WriteLine("{0} parsed as {1}", input, val);

input = "-120";
val = SByte.Parse(input);
Console.WriteLine("{0} parsed as {1}", input, val);
