SByte。将 C# 中的()方法与示例进行比较
原文:https://www . geesforgeks . org/sbyte-compare to-method-in-c-sharp-with-examples/
SByte。方法用于将当前实例与指定的对象或字节进行比较，并返回它们相对值的指示。此方法的重载列表中有 2 种方法，如下所示:
-
比较法 *CompareTo(Object) Method
SByte。比较法
此方法用于将当前实例与指定的 8 位有符号整数进行比较，并返回其相对值的指示。
语法:
cs public int CompareTo (sbyte value);这里，它使用 8 位有符号整数与当前实例进行比较。
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
下面的程序说明了 SByte 的使用。方法:
例 1:
```cs // C# program to demonstrate the // SByte.CompareTo(SByte) Method using System;
class GFG {
// Main Method public static void Main() {
// Declaring and initializing value1 sbyte value1 = 10;
// Declaring and initializing value2 sbyte value2 = 20;
// compare both SByte value // 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 10 is less than 20
```
例 2:
```cs // C# program to demonstrate the // SByte.CompareTo(SByte) 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(sbyte value1, sbyte 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
```
SByte。比较对象方法
此方法用于将当前实例与指定对象进行比较，并返回它们相对值的比较结果。
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:如果值不是字节，则抛出参数异常。
下面的程序说明了小数的使用。比较(对象)方法
例 1:
```cs // C# program to demonstrate the // SByte.CompareTo(object) Method using System;
class GFG {
// Main Method public static void Main() { try {
// Declaring and initializing value1 sbyte value1 = 10;
// Declaring and initializing value2 // explicit type casting the value 9 object value2 = (sbyte)9;
// compare both sbyte value // 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 SByte"); 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 // SByte.CompareTo(object) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { try {
// Declaring and initializing value1 sbyte 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 sbyte"); Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } ```
Output:
```cs value2 must be sbyte Exception Thrown: System.ArgumentException
```
