Returns the sort order of the current instance compared to the specified Object.

Parameters

obj

The Object to compare to the current instance.

Return Value

The return value is a negative number, zero, or a positive number reflecting the sort order of the current instance as compared to obj. For non-zero return values, the exact value returned by this method is unspecified. The following table defines the return value:

Return Value	Description
A negative number	Current instance < obj.
Zero	Current instance == obj.
A positive number	Current instance > obj, or obj is a null reference.

Exceptions

Exception Type	Condition
ArgumentException	obj is not a SByte and is not a null reference.

Description

[Note: This method is implemented to support the IComparable interface.]

System.SByte Structure, System Namespace

Returns the sort order of the current instance compared to the specified SByte.

Parameters

value

The SByte to compare to the current instance.

Return Value

The return value is a negative number, zero, or a positive number reflecting the sort order of the current instance as compared to value. For non-zero return values, the exact value returned by this method is unspecified. The following table defines the return value:

Return Value	Description
A negative number	Current instance < value.
Zero	Current instance == value.
A positive number	Current instance > value.

Description

[Note: This method is implemented to support the System.IComparable<SByte> interface.]

See Also

System.SByte Structure, System Namespace

Determines whether the current instance and the specified Object represent the same type and value.

Parameters

obj

The Object to compare to the current instance.

Return Value

true if obj represents the same type and value as the current instance. If obj is a null reference or is not an instance of SByte, returns false .

Description

[Note: This method overrides System.Object.Equals(System.Object).]

See Also

System.SByte Structure, System Namespace

Determines whether the current instance and the specified SByte represent the same value.

Parameters

obj

The SByte to compare to the current instance.

Return Value

true if obj represents the same value as the current instance; otherwise, false .

Description

[Note: This method is implemented to support the System.IEquatable<SByte> interface.]

See Also

System.SByte Structure, System Namespace

A Int32 containing the hash code for the current instance.

Description

The algorithm used to generate the hash code is unspecified.

[Note: This method overrides System.Object.GetHashCode.]

See Also

System.SByte Structure, System Namespace

Returns the specified String converted to a SByte value.

Parameters

s

A String containing the value to convert. The string is interpreted using the System.Globalization.NumberStyles.Integer style.

Return Value

The SByte value obtained from s.

Exceptions

Exception Type	Condition
ArgumentException	s is a null reference.
FormatException	s is not in the correct style.
OverflowException	s represents a number greater than System.SByte.MaxValue or less than System.SByte.MinValue.

Description

This version of System.SByte.Parse(System.String) is equivalent to System.SByte.Parse(System.String) (s, System.Globalization.NumberStyles.Integer, null ).

The string s is parsed using the formatting information in a NumberFormatInfo initialized for the current system culture. [Note: for more information, see System.Globalization.NumberFormatInfo.CurrentInfo.]

This method is not CLS-compliant. For a CLS-compliant alternative use System.Int16.Parse(System.String) (String).

Example

This example demonstrates the System.SByte.Parse(System.String)(String) method.

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

The output is

String: " 100 " <SByte> 100

Attributes

CLSCompliantAttribute(false)

Parameters

s

A String containing the value to convert. The string is interpreted using the style specified by style.

Exceptions

Exception Type	Condition
ArgumentNullException	s is a null reference.
FormatException	s is not in the correct style.
OverflowException	s represents a number greater than System.SByte.MaxValue or less than System.SByte.MinValue.

Description

This version of System.SByte.Parse(System.String) is equivalent to System.SByte.Parse(System.String) (s, style, null ).

The string s is parsed using the formatting information in a NumberFormatInfo initialized for the current system culture. [Note: For more information, see System.Globalization.NumberFormatInfo.CurrentInfo.]

This method is not CLS-compliant. For a CLS-compliant alternative use System.Int16.Parse(System.String)(String, NumberStyles).

Attributes

CLSCompliantAttribute(false)

System.SByte Structure, System Namespace

Returns the specified String converted to a SByte value.

Parameters

s

A String containing the value to convert. The string is interpreted using the System.Globalization.NumberStyles.Integer style.

Exceptions

Exception Type	Condition
ArgumentNullException	s is a null reference.
FormatException	s is not in the correct style.
OverflowException	s represents a number greater than System.SByte.MaxValue or less than System.SByte.MinValue.

Description

This version of System.SByte.Parse(System.String) is equivalent to System.SByte.Parse(System.String) (s, System.Globalization.NumberStyles.Integer, provider).

The string s is parsed using the culture-specific formatting information from the NumberFormatInfo instance supplied by provider. If provider is null or a NumberFormatInfo cannot be obtained from provider, the formatting information for the current system culture is used.
