C＃| Byte.CompareTo(Byte)方法

此方法用于将此实例与指定的8位无符号整数进行比较，并返回其相对值的指示。

句法：

public int CompareTo (byte value);

在此，该值是要比较的8位无符号整数。

返回值：该方法返回一个带符号的整数，该整数指示此实例和value的相对顺序。

• 小于零：此实例小于value 。
• 零：此实例等于value 。
• 大于零：此实例大于value 。

下面的程序说明了Byte.CompareTo(Byte)方法的用法：

范例1：

// C# program to demonstrate
// Byte.CompareTo(byte)
// Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring val1 and val2
        byte val1, val2;
  
        // intializing the val1, 
        // val2 and val3
        val1 = 12;
        val2 = 13;
  
        // getting compared constant
        // using CompareTo method
        int i = val2.CompareTo(val1);
  
        // checking the condition
        if (i > 0)
            Console.Write("val2 is greater than val1");
  
        else if (i < 0)
            Console.Write("val2 is less than val1");
  
        else
            Console.Write("val1 is equal to val1");
    }
}

输出：

val2 is greater than val1

范例2：

// C# program to demonstrate
// Byte.CompareTo(byte)
// Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // checking the condition
        // calling check() method
        check((byte)10, (byte)20);
        check((byte)30, (byte)20);
        check((byte)10, (byte)10);
        check((byte)5, (byte)7);
        check((byte)40, (byte)50);
        check((byte)1, (byte)2);
    }
  
    // Defining the check method
    public static void check(byte v1, byte v2)
    {
  
        // getting compared constant
        // using CompareTo() method
        int i = v1.CompareTo(v2);
  
        // checking the condition
        if (i > 0)
            Console.WriteLine(v1 + " is greater than " + v2);
  
        else if (i < 0)
            Console.WriteLine(v1 + " is less than " + v2);
  
        else
            Console.WriteLine(v1 + " is equal to " + v2);
    }
}

输出：

10 is less than 20
30 is greater than 20
10 is equal to 10
5 is less than 7
40 is less than 50
1 is less than 2
