Byte.CompareTo(byte) Method

public int CompareTo(byte value);

Summary

Returns the sort order of the current instance compared to the specified unsigned byte.

Parameters

value
The Byte 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 ValueDescription
A negative numberCurrent instance < value.
ZeroCurrent instance == value.
A positive numberCurrent instance > value.

Description

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

Byte.CompareTo(System.Object) Method

public int CompareTo(object value);

Summary

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

Parameters

value

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:

Summary

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

Parameters

obj
The Object to compare to the current instance.

Return Value

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

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 Byte, returns false .

Byte.Parse(System.String) Method

public static byte Parse(string s);

Summary

Returns the specified String converted to a Byte value.

Parameters

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

Return Value

The Byte value obtained from s.

Exceptions

Exception TypeCondition
ArgumentNullExceptions is a null reference.
FormatExceptions is not in the correct style.
OverflowExceptions represents a number greater than System.Byte.MaxValue or less than System.Byte.MinValue.

Description

This version of System.Byte.Parse(System.String) is equivalent to System.Byte.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.]

Example

The following example demonstrates the System.Byte.Parse(System.String) method.

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

Description

This version of System.Byte.Parse(System.String) is equivalent to System.Byte.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 .]

Parameters

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