Int16.CompareTo方法用於將當前實例與指定的對象或另一個Int16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否小於，等於或大於指定對象或其他Int16實例的值。此方法的重載列表中有2種方法，如下所示：
- CompareTo(Int16)方法
- CompareTo(Object)方法
Int16.CompareTo(Int16)方法
此方法用於將當前實例與指定的16位帶符號整數進行比較，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16位帶符號整數的值。
用法:
public int CompareTo (short value);
在這裏，它需要一個整數來進行比較。
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Int16.CompareTo(Int16)方法的使用
示例1:
// C# program to demonstrate the
// Int16.CompareTo(Double) Method
using System;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing value1
short value1 = 1;
// Declaring and initializing value2
short value2 = 5;
// 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：
1 is less than 5
示例2:
// C# program to demonstrate the
// Int16.CompareTo(Double) 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(short value1,
short 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
Int16.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value不為null，則拋出ArgumentException。
下麵的程序演示了Int16.CompareTo(Object)方法的使用
示例1:
// C# program to demonstrate the
// Int16.CompareTo(object) Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing value1
short value1 = 10;
// Declaring and initializing value2
object value2 = (short)9.8765400;
// 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 short");
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
// Int16.CompareTo(object) Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing value1
short 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 short");
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
輸出：
value2 must be short Exception Thrown: System.ArgumentException
