C# SByte.CompareTo()用法及代碼示例

SByte.CompareTo()方法用於將當前實例與指定的對象或SByte進行比較，並返回其相對值的指示。此方法的重載列表中有2種方法，如下所示：

CompareTo(SByte)方法
CompareTo(Object)方法

SByte.CompareTo(SByte) Method

此方法用於將當前實例與指定的8位帶符號整數進行比較，並返回其相對值的指示。

用法:

public int CompareTo (sbyte value);

在這裏，它需要一個8位有符號整數與當前實例進行比較。

返回值：它返回一個32位帶符號的數字，指示當前實例和value參數的相對值，如下所示：

小於零：如果當前實例
零：如果當前實例=值
大於零：如果當前實例>值

以下示例程序旨在說明SByte.CompareTo(SByte)方法的用法：

示例1:

// C# program to demonstrate the 
// SByte.CompareTo(SByte) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring and initializing value1 
        sbyte value1 = 10; 
  
        // Declaring and initializing value2 
        sbyte value2 = 20; 
  
        // compare both SByte value 
        // 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); 
    } 
}

輸出：

10 is less than 20

示例2:

// C# program to demonstrate the 
// SByte.CompareTo(SByte) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(5, 7); 
        get(30, 20); 
        get(10, 20); 
        get(7, -12); 
    } 
  
    // defining get() method 
    public static void get(sbyte value1, 
                           sbyte value2) 
    { 
  
        // 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); 
    } 
}

輸出：

5 is less than 7
30 is greater than 20
10 is less than 20
7 is greater than -12

SByte.CompareTo(Object) Method

此方法用於將當前實例與指定對象進行比較，並返回其相對值的比較。

用法:

public int CompareTo (object value);

在這裏，它需要對象與該實例進行比較，或者為null。

返回值：它返回一個32位帶符號的數字，指示當前實例和value參數的相對值，如下所示：

小於零：如果當前實例
零：如果當前實例=值
大於零：如果當前實例>值

異常：如果value不是SByte，則拋出ArgumentException。

下麵的程序說明Decimal.CompareTo(Object)方法的用法

示例1:

// C# program to demonstrate the 
// SByte.CompareTo(object) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            sbyte value1 = 10; 
  
            // Declaring and initializing value2 
            // explicit type casting the value 9 
            object value2 = (sbyte)9; 
  
            // compare both sbyte value 
            // 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 SByte"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

10 is greater than 9

示例2:對於ArgumentException

// C# program to demonstrate the 
// SByte.CompareTo(object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            sbyte value1 = 10; 
  
            // Declaring and initializing value2 
            object value2 = 1 / 3; 
  
            // 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 sbyte"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

value2 must be sbyte
Exception Thrown: System.ArgumentException
