RSCG – PartiallyApplied
 
 

If you need to curry functions,you can use this package

This is how you can use PartiallyApplied .

The code that you start with is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
  </PropertyGroup>
	<PropertyGroup>
		<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
		<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
	</PropertyGroup>

	<ItemGroup>
    <PackageReference Include="PartiallyApplied" Version="1.3.0" />
  </ItemGroup>

</Project>

The code that you will use is

using System;

namespace PartFunc;
class Program
{
    static void Main(string[] args)
    {
        
        var disc10Percent = Partially.Apply(Accounting.Discount,1/10f);
        Console.WriteLine(disc10Percent(disc10Percent(100)));
        
    }
}

namespace PartFunc;

public class Accounting
{
    public static float Discount( float discount,float price)
    {
        var val= price * (1- discount);
        return val;
    }
}

The code that is generated is

using System;

#nullable enable
public static partial class Partially
{
	public static Func<float,float> Apply(Func<float,float,float> method,float discount) =>
		new((price) => method(discount,price));
}
