C# UInt16.CompareTo()用法及代码示例

UInt16.CompareTo方法用于将当前实例与指定对象或另一个UInt16实例进行比较。它返回一个整数，该整数显示当前实例的值是小于，等于还是大于指定对象或另一个UInt16实例的值。此方法的重载列表中有2种方法，如下所示：

CompareTo(UInt16)方法
CompareTo(Object)方法

UInt16.CompareTo(UInt16)方法

此方法用于将当前实例与指定的16位无符号整数进行比较，并返回一个整数，该整数显示当前实例的值是否小于，等于或大于指定的16位无符号整数的值。

用法:

public int CompareTo (ushort value);

在这里，它需要一个无符号整数进行比较。

返回值：它返回一个32位带符号的数字，指示当前实例和value参数的相对值，如下所示：

小于零：如果当前实例
零：如果当前实例=值
大于零：如果当前实例>值

以下示例程序旨在说明UInt16.CompareTo(UInt16)方法的用法

示例1:

// C# program to demonstrate the 
// UInt16.CompareTo(UInt16) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring and initializing value1 
        ushort value1 = 7; 
  
        // Declaring and initializing value2 
        ushort value2 = 98; 
  
        // 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); 
    } 
}

输出：

7 is less than 98

示例2:

// C# program to demonstrate the 
// UInt16.CompareTo(UInt16) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(54, 77); 
        get(70, 95); 
        get(10, 24); 
        get(45, 45); 
    } 
  
    // defining get() method 
    public static void get(ushort value1, 
                           ushort 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); 
    } 
}

输出：

54 is less than 77
70 is less than 95
10 is less than 24
45 is equal to 45

UInt16.CompareTo(Object)方法

此方法用于将当前实例与指定对象进行比较，并返回一个整数，该整数指示当前实例的值是小于，等于还是大于对象的值。

用法:

public int CompareTo (object value);

在这里，它需要对象与该实例进行比较，或者为null。

返回值：它返回一个32位带符号的数字，指示当前实例和value参数的相对值，如下所示：

小于零：如果当前实例
零：如果当前实例=值
大于零：如果当前实例>值

异常：如果值不是UInt16，则抛出ArgumentException。

以下示例程序旨在说明UInt16.CompareTo(Object)方法的用法

示例1:

// C# program to demonstrate the 
// UInt16.CompareTo(object) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            ushort value1 = 10; 
  
            // Declaring and initializing value2 
            object value2 = (ushort)56; 
  
            // 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 UInt16"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

输出：

10 is less than 56

示例2:对于ArgumentException

// C# program to demonstrate the 
// UInt16.CompareTo(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            ushort value1 = 150; 
  
            // Declaring and initializing value2 
            object value2 = 1 / 4; 
  
            // 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 UInt16"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

输出：

value2 must be null or an instance of UInt16
Exception Thrown: System.ArgumentException
