C# UInt32.CompareTo()用法及代碼示例

UInt32.CompareTo方法用於將當前實例與指定對象或另一個UInt32實例進行比較。它返回一個整數，該整數顯示當前實例的值是小於，等於還是大於指定對象或另一個UInt32實例的值。此方法的重載列表中有2種方法，如下所示：

CompareTo(UInt32)方法
CompareTo(Object)方法

UInt32.CompareTo(UInt32)方法

此方法用於將當前實例與指定的32位無符號整數進行比較，並返回一個整數，該整數顯示當前實例的值是否小於，等於或大於指定的32位無符號整數的值。

用法:

public int CompareTo (uint value);

在這裏，它需要一個無符號整數進行比較。

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UInt32.CompareTo(UInt32)方法的用法

示例1:

// C# program to demonstrate the 
// UInt32.CompareTo(UInt32) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring and initializing value1 
        uint value1 = 1231; 
  
        // Declaring and initializing value2 
        uint value2 = 5123; 
  
        // 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：

1231 is less than 5123

示例2:

// C# program to demonstrate the 
// UInt32.CompareTo(UInt32) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(34425, 7343); 
        get(340, 67520); 
        get(7810, 2890); 
        get(700, 700); 
    } 
  
    // defining get() method 
    public static void get(uint value1, 
                           uint 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：

34425 is greater than 7343
340 is less than 67520
7810 is greater than 2890
700 is equal to 700

UInt32.CompareTo(Object)方法

此方法用於將當前實例與指定對象進行比較，並返回一個整數，該整數指示當前實例的值是小於，等於還是大於對象的值。

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：如果值不是UInt32，則拋出ArgumentException。

以下示例程序旨在說明UInt32.CompareTo(Object)方法的用法

示例1:

// C# program to demonstrate the 
// UInt32.CompareTo(Object) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            uint value1 = 11220; 
  
            // Declaring and initializing value2 
            object value2 = (uint)2347.84376; 
  
            // 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 null"+ 
                       " or an instance of UInt32"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

11220 is greater than 2347

示例2:對於ArgumentException

// C# program to demonstrate the 
// UInt32.CompareTo(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            uint value1 = 1790; 
  
            // Declaring and initializing value2 
            object value2 = 1 / 7; 
  
            // 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 null"+ 
                       " or an instance of UInt32"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

value2 must be null or an instance of UInt32
Exception Thrown: System.ArgumentException
