C# Byte.CompareTo(Object)用法及代碼示例

此方法用於將當前實例與指定對象進行比較，並返回其相對值的符號。無論值如何，Byte的任何實例都將被視為大於null。

用法:

public int CompareTo (object value);

在這裏，它需要一個對象進行比較，或者為null。

返回值：它返回一個帶符號的整數，指示當前實例和value參數的相對順序，如下所示：

小於零：如果當前實例
零：如果當前實例=值
大於零：如果Current Instance> value或value為null。

異常：如果value不是Byte，則拋出ArgumentException。

以下示例程序旨在說明Byte.CompareTo(Object)方法的用法

示例1:

// C# program to demonstrate the 
// Byte.CompareTo(object) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            byte value1 = 10; 
  
            // Declaring and initializing value2 
            // converting to byte using explicit 
            // type casting 
            object value2 = (byte)87; 
  
            // using CompareTo() method 
            int status = value1.CompareTo(value2); 
  
            // checking the status 
            if (status > 0) 
                Console.WriteLine("{0} is greater than {1}", 
                                            value1, value2); 
  
            else if (status < 0) 
                Console.WriteLine("{0} is less than {1}", 
                                         value1, value2); 
            else
                Console.WriteLine("{0} is equal to {1}", 
                                        value1, value2); 
        } 
  
        catch (ArgumentException e)  
        { 
            Console.WriteLine("value2 must be Byte"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

10 is less than 87

示例2:對於ArgumentException

// C# program to demonstrate the 
// Byte.CompareTo(object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            byte value1 = 10; 
  
            // Declaring and initializing value2 
            object value2 = (long)569874514; 
  
            // using CompareTo() method 
            int status = value1.CompareTo(value2); 
  
            // checking the status 
            if (status > 0) 
                Console.WriteLine("{0} is greater than {1}", 
                                            value1, value2); 
  
            else if (status < 0) 
                Console.WriteLine("{0} is less than {1}", 
                                         value1, value2); 
            else
                Console.WriteLine("{0} is equal to {1}", 
                                        value1, value2); 
        } 
  
        catch (ArgumentException e)  
        { 
            Console.WriteLine("value2 must be Byte"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

value2 must be Byte
Exception Thrown: System.ArgumentException
