Elfo.ExtensionMethods

How to add an extension method

• Every extended type has it's own project

  i.e:

  • string -> Elfo.ExtensionMethods.String

  • Boolean -> Elfo.ExtensionMethods.Boolean

• If the project related to your type doesn't exist, then create it (type is .NET Standard Library)

  

  and replace the content of the .csproj with this:

  <Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
      <TargetFrameworks>net40;net452;net471;netstandard2.0</TargetFrameworks>
      <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    </PropertyGroup>
    <PropertyGroup Condition=" '$(TargetFramework)' == 'net40' ">
      <DefineConstants>NET40</DefineConstants>
    </PropertyGroup>
    <PropertyGroup Condition=" '$(TargetFramework)' == 'net452' ">
      <DefineConstants>NET452</DefineConstants>
    </PropertyGroup>
    <PropertyGroup Condition=" '$(TargetFramework)' == 'net471' ">
      <DefineConstants>NET471</DefineConstants>
    </PropertyGroup>
    <PropertyGroup Condition=" '$(TargetFramework)' == 'netstandard2.0' ">
      <DefineConstants>NETSTD20</DefineConstants>
    </PropertyGroup>
  </Project>

  • Add a new partial static class with this naming convention: *Extended type*ExtensionMethods

    i.e: String -> StringExtensionMethods

  • Add a new folder at the same level and with the same name of the class created above

  • Inside the folder, create one .cs file for each extension method you want to add.

    Name it like the method you want to create, inside the .cs file extend the partial class created in the step above.

    Inside the class add as many overloads as you want.
