int? num1 = 5; int? num2 = null; bool result = num1.Equals(num2); // returns false
decimal? amount1 = null; decimal? amount2 = null; bool result = amount1.Equals(amount2); // returns trueIn this example, we have two nullable decimal types with null values. The Nullable Equals method returns true because both are null. The Nullable.Equals method is part of the C# language and is included in the System namespace, which is part of the .NET Framework. Therefore, no additional package or library is required.
