Nov 4, 2008 · You cannot declare implicit conversions on enum types, because they can't define methods. The C# implicit keyword compiles into a method starting with 'op_', and it wouldn't work in this case. answered Nov 4, 2008 at 12:16. Igal Tabachnik.
TargetType ToTargetType(); Then in an abstract base class you can define an implicit/explicit cast and have the cast operator just call the interface method in which you define your actual cast logic e.g. public TargetType ToTargetType() // Actual cast logic goes here. return (TargetType)this;
Apr 22, 2013 · In VB.NET, use the Widening CType operator to create an implicit conversion: Public Shared Widening Operator CType(ByVal p1 As C1) As C2. End Operator. The opposite, an explicit conversion, can be done by swapping Narrowing for Widening in the above definition. Maybe I don't understand the difference between Widening and Narrowing.
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 } }
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) Then you can use it like this: type A() = class end.
Aug 18, 2021 · The section explains how to write a parser from multiple data types. It gives the example below. trait StrParser[T]{ def parse(s: String): T } object StrParser{. implicit object ParseInt extends StrParser[Int]{. def parse(s: String) = s.toInt. } implicit object ParseBoolean extends StrParser[Boolean]{. def parse(s: String) = s.toBoolean.
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.
Jul 2, 2011 · 16. This is not specific to extension methods. C# won't implicitly cast an object to another type unless there is a clue about the target type. Assume the following: public static implicit operator B(A obj) { ... public static implicit operator C(A obj) { ... public void Foo() { ... public void Foo() { ... Which method would you expect to be ...
Mar 7, 2014 · type TMyRec1 = record Field1 : Integer; end; TMyRec2 = record Field2: Integer; class operator Implicit(a: TMyRec2): TMyRec1; class operator Implicit(a: TMyRec1): TMyRec2; end; Quoting from the help: Implicit conversions should be provided only where absolutely necessary, and reflexivity should be avoided. It is best to let type B implicitly ...
