Int16。C# 中的 CompareTo()方法
原文:https://www . geesforgeks . org/int 16-compare to-method-in-c-sharp/
Int16。比较方法用于将当前实例与指定对象或另一个 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小于、等于还是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:

比较(Int16)方法 *CompareTo(Object) Method
Int16。比较(Int16)方法
此方法用于将当前实例与指定的 16 位有符号整数进行比较,并返回一个整数,该整数显示当前实例的值是小于、等于还是大于指定的 16 位有符号整数的值。
语法:
cs public int CompareTo (short value);
这里,需要一个整数来比较。
返回值:返回一个 32 位有符号数,表示当前实例和值参数的相对值,如下所示:
- 小于零:如果当前实例<值
- 如果当前实例=值,则为零:
- 大于零:如果当前实例>值
以下程序说明了 Int16 的使用。比较(Int16) 方法
例 1:
```cs // 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); } } ```
Output:
```cs 1 is less than 5
```
例 2:
```cs // 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); } } ```
Output:
```cs 5 is less than 7 30 is greater than 20 10 is less than 20 7 is greater than -12
```
Int16。比较对象方法
此方法用于将当前实例与指定的对象进行比较,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。
语法:
cs public int CompareTo (object value);
这里,它将对象与这个实例进行比较,或者为 null。
返回值:返回一个 32 位有符号数,表示当前实例和值参数的相对值,如下所示:
- 小于零:如果当前实例<值
- 如果当前实例=值,则为零:
- 大于零:如果当前实例>值
异常:如果值不为空,则抛出参数异常。
以下程序说明了 Int16 的使用。比较(对象)方法
例 1:
```cs // 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); } } } ```
Output:
```cs 10 is greater than 9
```
示例 2: 适用于参数异常
```cs // 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); } } } ```
Output:
```cs value2 must be short Exception Thrown: System.ArgumentException
```
