RSCG – dunet
Add union types to C# – similar with F#/TS discriminated unions
Check his examples- awesome
This is how you can use dunet .
The code that you start with is
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net7.0</TargetFramework>
<ImplicitUsings>enable</ImplicitUsings>
<Nullable>enable</Nullable>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Dunet" Version="1.8.0">
<PrivateAssets>all</PrivateAssets>
<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>
</ItemGroup>
<PropertyGroup>
<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
</PropertyGroup>
</Project>
The code that you will use is
// See https://github.com/domn1995/dunet for more examples
using duneDemo;
Console.WriteLine(WhatIsTheString.FromString("1"));
Console.WriteLine(WhatIsTheString.FromString("Andrei"));
Console.WriteLine(WhatIsTheString.FromString("1970-04-16"));
Console.WriteLine("Enter something - 1, 1970-04-16 or Andrei !");
var readLine = Console.ReadLine();
var opt= WhatIsTheString.FromString(readLine);
Console.WriteLine(opt);
//if if it long
opt.MatchIsLong(
l => Console.WriteLine("is long " + l.value),
() => Console.WriteLine("is not long")
) ;
//C# switch
var x=opt switch
{
WhatIsTheString.IsLong l => "is long " +l.value,
WhatIsTheString.IsDate d=> "is date "+ d.value,
WhatIsTheString.IsString s=>"is string "+ s.value,
WhatIsTheString.IsNullWhiteSpace w=>"no data",
_ => throw new NotImplementedException()
};
Console.WriteLine(x);
using Dunet;
namespace duneDemo;
[Union]
partial record WhatIsTheString
{
partial record IsString(string value);
partial record IsLong(long value);
partial record IsDate(DateTime value);
partial record IsNullWhiteSpace();
public static WhatIsTheString FromString(string? value)
{
if (string.IsNullOrWhiteSpace(value))
return new IsNullWhiteSpace();

{
return new IsLong(longValue);
}
if(DateTime.TryParse(value, out var dateTimeValue))
{
return new IsDate(dateTimeValue);
}
return new IsString(value);
}
}
The code that is generated is
