Nov 4, 2008 · There is a solution. Consider the following: public sealed class AccountStatus { public static readonly AccountStatus Open = new AccountStatus(1); public static readonly AccountStatus Closed = new AccountStatus(2); public static readonly SortedList<byte, AccountStatus> Values = new SortedList<byte, AccountStatus>(); private readonly byte Value; private AccountStatus(byte value) { this.Value ...
You cannot define casts or operator overloading on interfaces. Since an interface is a contract that describes the members which will always be available (either as an explicit cast to that interface or as public members) and nothing more you cannot rely on interfaces to contain any sort of built in logic such as how to cast or how operators will perform with that interface.
As others have pointed out, there is no way to do implicit conversion in F#. However, you could always create your own operator to make it a bit easier to explicitly convert things (and to reuse any op_Implicit definitions that existing classes have defined): let inline (!>) (x:^a) : ^b = ((^a or ^b) : (static member op_Implicit : ^a -> ^b) x)
Apr 22, 2013 · In C#, you can use the implicit keyword to define an implicit user-defined type conversion operator. In VB.NET, you can define a CType conversion operator that will explicitly convert a user-defined type into another type. Is there a way to declare an implicit conversion operator in VB.NET? I can't seem to find any information on this....
Apr 1, 2017 · The C# specification is clear, your implicit operator must convert either to or from the type in which it's declared. It has to be an exact conversion, and since the declaring type is exactly MyClass<T>, the conversion has to be either to or from that. See e.g. Can i use a generic implicit or explicit operator? C# and C# Implicit operator with ...
Apr 2, 2011 · No, you can't. The implicit operator has to be defined as a member of one of the classes. However, you can define an extension method (your example didn't work as extension methods have to be in a public static class). public static class ConverterExtensions { public static Vector ToVector (this Vector3 input) { //convert } }
Aug 18, 2021 · implicit def ParseSeq[T](implicit p: StrParser[T]): StrParser[Seq[T]] = new StrParser[Seq[T]]{ def parse(s: String) = s.split(',').toSeq.map(p.parse) } Also note that the book defines ParseSeq as a generic method with parameter name T , which is better generic parameter name than one mathcing existing type (i.e. Int ):
Jul 2, 2011 · @Anton: That is possible, but would complicate the language and possibly hiding the side effects. And after all, how'd you feel if a working code suddenly breaks when you define a new implicit operator on a class :) It's just simpler to force the explicit type declaration everywhere. –
Jun 13, 2022 · public interface IUnit { static abstract double ToScaled(double v); static abstract double ToSI(double v); } // these interfaces exist so you can box the struct or use them as a generic constraint public interface IScalableNumber { double SI { get; set; } double Scaled { get; set; } } public interface IScalableNumber<TSelf> : IScalableNumber, IAdditionOperators<TSelf, double, TSelf> // more I ...
Jul 23, 2013 · The conversion operator you provided is already implicit.The problem you face is that the compiler is seeing two different conversion sequences from B to const A&, the derived-to-base reference and your user provided conversion.
