Int64。C# 中的 Equals 方法及示例
原文:https://www . geesforgeks . org/int 64-equals-method-in-c-sharp-with-examples/
Int64。Equals()方法用于获取一个值，该值显示当前实例是否等于指定对象或 Int64。此方法的重载列表中有 2 种方法，如下所示:
-
等于(Int64)方法 *Equals(Object) Method
Int64。等于(Int64)
此方法用于返回一个值，该值指示当前实例是否等于指定的 Int64 值。
语法:public bool Equals(long obj)； 这里，需要一个 Int64 值来与这个实例进行比较。
返回值:如果对象与该实例具有相同的值，则该方法返回真，否则返回假。
以下程序说明了 Int64 的使用。Equals(Int64) 方法:
例 1:
```cs // C# program to demonstrate the // Int64.Equals(Int64) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { // Declaring and initializing value1 long value1 = 45643242;
// Declaring and initializing value2 long value2 = 2564233;
// using Equals(Int64) 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 45643242 is not equal to 2564233
```
例 2:
```cs // C# program to demonstrate the // Int64.Equals(Int64) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() {
// calling get() method get(44355, 578); get(423445, 423445); get(12560, 28960); get(778, 798); }
// defining get() method public static void get(long value1, long value2) {
// using Equals(Int64) 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 44355 is not equal to 578 423445 is equal to 423445 12560 is not equal to 28960 778 is not equal to 798
```
Int64。等于(对象)方法
此方法用于返回一个值，该值指示当前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 Int64 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 // Int64.Equals(Object) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { // Declaring and initializing value1 long value1 = 1879650;
// Declaring and initializing value2 object value2 = 1/45;
// 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 1879650 is not equal to 0
```
例 2:
```cs // C# program to demonstrate the // Int64.Equals(Object) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { // calling get() method get(54547, 54585); get(555, 489); get(10450, 10450); get(745, 745); }
// defining get() method public static void get(long value1, object value2) {
// 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 54547 is not equal to 54585 555 is not equal to 489 10450 is not equal to 10450 745 is equal to 745
```
