单身。C# 中的 Equals()方法及示例
原文:https://www . geesforgeks . org/single-equals-method-in-c-sharp-with-examples/
单身。Equals()方法用于获取一个值，该值指示 Single 的两个实例是否代表相同的值。此方法的重载列表中有 2 种方法，如下所示:
-
相等(单一)方法 *Equals(Object) Method
单身。相等(单一)方法
此方法用于返回一个值，该值指示此实例和指定的 Single 对象是否表示相同的值。
语法:public bool Equals(float obj)； 在这里，它需要一个单一的对象来比较这个实例。
返回值:如果 obj 等于该实例，则该方法返回真，否则返回假。
以下程序说明了 Single 的使用。Equals() 方法:
例 1:
```cs // C# program to demonstrate the // Single.Equals(Single) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { // Declaring and initializing value1 float value1 = 10.5f;
// Declaring and initializing value2 float value2 = 20.6f;
// using Equals(Single) method bool status = value1.Equals(value2);
// checking the status if (status) Console.WriteLine("{0} is equal to {1}", value1, value2); else Console.WriteLine("{0} is not equal to {1}", value1, value2); } } ```
Output:
```cs 10.5 is not equal to 20.6
```
例 2:
```cs // C# program to demonstrate the // Single.Equals(Single) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() {
// calling get() method get(5f, 5f); get(5.5f, 4.5f); get(10f, 10f); get(7.5f, 19.5f); }
// defining get() method public static void get(float value1, float value2) {
// using Equals(Single) method bool status = value1.Equals(value2);
// checking the status if (status) Console.WriteLine("{0} is equal to {1}", value1, value2); else Console.WriteLine("{0} is not equal to {1}", value1, value2); } } ```
Output:
```cs 5 is equal to 5 5.5 is not equal to 4.5 10 is equal to 10 7.5 is not equal to 19.5
```
单身。等于(对象)方法
此方法用于返回一个值，该值指示此实例是否等于指定的对象。
语法:公共覆盖 bool Equals(对象 obj)； 在这里，需要一个对象来与这个实例进行比较。
返回值:如果对象是 Single 的实例，并且等于该实例的值，则该方法返回 true ，否则返回 false。
以下程序说明了上述方法的使用:
例 1:
```cs // C# program to demonstrate the // Single.Equals(Single) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { // Declaring and initializing value1 float value1 = 10.5f;
// Declaring and initializing value2 object value2 = 3 / 36;
// using Equals(object) method bool status = value1.Equals(value2);
// checking the status if (status) Console.WriteLine("{0} is equal to {1}", value1, value2); else Console.WriteLine("{0} is not equal to {1}", value1, value2); } } ```
Output:
```cs 10.5 is not equal to 0
```
例 2:
```cs // C# program to demonstrate the // Single.Equals(object) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { // calling get() method get(5f, new Object()); get(5.5f, (float)5.5); get(10f, 10); get(7.5f, 2 / 5); }
// defining get() method public static void get(float value1, object value2) {
// compare both float value // using Equals(object) method bool status = value1.Equals(value2);
// checking the status if (status) Console.WriteLine("{0} is equal to {1}", value1, value2); else Console.WriteLine("{0} is not equal to {1}", value1, value2); } } ```
Output:
```cs 5 is not equal to System.Object 5.5 is equal to 5.5 10 is not equal to 10 7.5 is not equal to 0
```
