Int16.CompareTo方法用于将当前实例与指定的对象或另一个Int16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否小于，等于或大于指定对象或其他Int16实例的值。此方法的重载列表中有2种方法，如下所示：
- CompareTo(Int16)方法
- CompareTo(Object)方法
Int16.CompareTo(Int16)方法
此方法用于将当前实例与指定的16位带符号整数进行比较，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位带符号整数的值。
用法:
public int CompareTo (short value);
在这里，它需要一个整数来进行比较。
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);
}
}
输出：
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);
}
}
输出：
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value不为null，则抛出ArgumentException。
下面的程序演示了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);
}
}
}
输出：
10 is greater than 9
示例2:对于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);
}
}
}
输出：
value2 must be short Exception Thrown: System.ArgumentException
