C＃中的字节结构

在C＃中，字节结构用于表示8位无符号整数。 Byte是一个不可变的值类型，Byte的范围是0到255。此类允许您创建Byte数据类型，并且可以对其进行数学和按位运算，例如加法，减法，乘法，除法，XOR和AND等。

Field	Description
MaxValue	It is the largest possible value of a Byte. This field is constant.
MinValue	It is the smallest possible value of a Byte. This field is constant.

例子：

// C# program to illustrate the concept
// of MaxValue and MinValue fields in Byte
using System;
  
public class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Display the minimum and
        // the maximum value of Byte
        Console.WriteLine("The minimum value "+
                 "of Byte: {0}", Byte.MinValue);
  
        Console.WriteLine("The maximum value "+
                 "of Byte: {0}", Byte.MaxValue);
    }
}

输出：

The minimum value of Byte: 0
The maximum value of Byte: 255

方法

Method	Description
CompareTo(Object)	Compares the current instance to a specified object and returns a sign of their relative values.
CompareTo(Byte)	Compares this instance to a specified 8-bit unsigned integer and returns an indication of their relative values.
Equals(Object)	To get a value which indicates whether the current instance is equal to a specified object or not.
Equals(Byte)	Returns a value indicating whether this instance and a specified Byte object represent the same value.
GetHashCode()	Returns the hash code for this instance.
GetTypeCode()	Returns the TypeCode for value type Byte.
Parse()	Converts the string representation of a number to its Byte equivalent.
ToString()	Converts the value of the current Byte object to its equivalent string representation.
TryParse()	Tries to convert the string representation of a number to its Byte equivalent, and returns a value that indicates whether the conversion succeeded.

例子：

// C# program to illustrate the concept
// of CompareTo(Byte) method in Byte
using System;
  
public class GFG {
  
    // Main method
    static public void Main()
    {
  
        // val1, val2, and val3 are of byte type
        byte val1 = 32;
        byte val2 = 40;
        byte val3 = 10;
  
        // Display the comparison
        // Using CompareTo(Byte) method
        Console.WriteLine("Comparison 1: {0}",
                         val1.CompareTo(val2));
  
        Console.WriteLine("Comparison 2: {0}", 
                         val2.CompareTo(val3));
  
        Console.WriteLine("Comparison 3: {0}", 
                        val3.CompareTo(val3));
  
        Console.WriteLine("Comparison 4: {0}",
                         val1.CompareTo(val3));
    }
}

输出：

Comparison 1: -8
Comparison 2: 30
Comparison 3: 0
Comparison 4: 22
