C# DateTimeOffset.GetHashCode()用法及代碼示例

C# 中的 DateTimeOffset.GetHashCode 方法用於返回當前 DateTimeOffset 對象的哈希碼。此方法返回一個 32 位有符號整數哈希碼。

用法

以下是語法 -

public override int GetHashCode ();

示例

現在讓我們看一個實現 DateTimeOffset.GetHashCode() 方法的例子 -

using System;
public class Demo {
   public static void Main() {
      DateTimeOffset dateTimeOffset1 = new DateTimeOffset(2019, 09, 10, 6, 20, 10, new TimeSpan(-5, 0, 0));
      DateTimeOffset dateTimeOffset2 = new DateTimeOffset(2019, 11, 12, 8, 20, 10, new TimeSpan(-5, 0, 0));
      Console.WriteLine("DateTimeOffset1 = {0}", dateTimeOffset1);
      int hash1 = dateTimeOffset1.GetHashCode();
      Console.WriteLine("DateTimeOffset1 HashCode = {0}", hash1);
      int hash2 = dateTimeOffset2.GetHashCode();
      Console.WriteLine("DateTimeOffset2 HashCode = {0}", hash2);
      Console.WriteLine("DateTimeOffset2 = {0}", dateTimeOffset2);
      int res = DateTimeOffset.Compare(dateTimeOffset1, dateTimeOffset2);
      // returns <0 since DateTimeOffset1 is earlier than DateTimeOffset2 Console.WriteLine(res);
   }
}

輸出

這將產生以下輸出 -

DateTimeOffset1 = 9/10/2019 6:20:10 AM -05:00
DateTimeOffset1 HashCode = -543087392
DateTimeOffset2 HashCode = 64112243
DateTimeOffset2 = 11/12/2019 8:20:10 AM -05:00

示例

現在讓我們看另一個例子來實現 DateTimeOffset.GetHashCode() 方法 -

using System;
public class Demo {
   public static void Main() {
      DateTimeOffset dateTimeOffset1 = new DateTimeOffset(2019, 11, 10, 6, 20, 10, new TimeSpan(-5, 0, 0));
      Console.WriteLine("DateTimeOffset = {0}", dateTimeOffset1);
      int hash = dateTimeOffset1.GetHashCode();
      Console.WriteLine("DateTimeOffset HashCode = {0}", hash);
   }
}

輸出

這將產生以下輸出 -

DateTimeOffset = 11/10/2019 6:20:10 AM -05:00
DateTimeOffset HashCode = -92293937
