Original Readme​

note

EmbedResourceCSharp

This is a C# Source Generator. This let you embed files in your application. You do not need to use Assembly.GetManifestResourceStream anymore.

How to use

Install​

dotnet add package EmbedResourceCSharp

Add only 1 package to your C# project.

Embedding file​

Provide that there are some files like below.

  • projectFolder/
    • Example.csproj
    • ExampleProgram.cs
    • resourceFileA.txt
namespace Example
{
    // partial methods require partial class/struct!
    public partial class ExampleClass
    {
        /*
            The relative file path from C# project folder should be specified.
            The return value type must be System.ReadOnlySpan<byte>.
            No parameter must exist.
            The method must be static and partial.
            The accessibility of the method does not matter.
        */
        [EmbedResourceCSharp.FileEmbed("resourceFileA.txt")]
        private static partial System.ReadOnlySpan<byte> GetFileContentA();
    }
}

You can get file content byte sequence with static partial method System.ReadOnlySpan<byte> GetFileContentA.

Embedding files under specific folder​

Provide that there are some files like below.

  • projectFolder/
    • Example2.csproj
    • ExampleProgram.cs
  • folderB/
    • resourceA.txt
    • resourceB.txt
    • folderB_C/
      • resourceC.txt
    • resourceD.csv
namespace Example2
{
    // partial methods require partial class/struct!
    public partial class ExampleClass
    {
        /*
            The relative folder path from C# project folder should be specified. The folder path should end with slash or backslash.
            The return value type must be System.ReadOnlySpan<byte>.
            One parameter must exist and its type must be System.ReadOnlySpan<char>. The parameter name does not matter.
            The method must be static and partial.
            The accessibility of the method does not matter.
        */
        [EmbedResourceCSharp.FolderEmbed("../folderB/", "*.txt")]
        private static partial System.ReadOnlySpan<byte> GetResouceFileContent(System.ReadOnlySpan<char> path);

        public static void Main()
        {
            // Specify relative path from the folder.
            var aContent = GetResouceFileContent("resourceA.txt");
            var bContent = GetResouceFileContent("resourceB.txt");
            var cContent = GetResouceFileContent("folderB_C/resourceC.txt");
            // var dContent = GetResouceFileContent("resourceD.csv");
            // Above method call throws an FileNotFoundException!
        }
    }
}

You can include all files under the target folder recursively. You can filter file with search pattern.

How to use​

Example ( source csproj, source files )​

This is the CSharp Project that references EmbedResourceCSharp

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
    <PropertyGroup>
        <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
        <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)\GX</CompilerGeneratedFilesOutputPath>
    </PropertyGroup>
  <ItemGroup>
    <None Remove="createDB.txt" />
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Include="createDB.txt" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="EmbedResourceCSharp" Version="1.1.3">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

</Project>

Generated Files​

Those are taken from $(BaseIntermediateOutputPath)\GX

namespace EmbedResourceCSharp
{
    internal enum PathSeparator
    {
        AsIs,
        Slash,
        BackSlash,
    }

    [global::System.AttributeUsage(global::System.AttributeTargets.Method, AllowMultiple = false)]
    internal sealed class FileEmbedAttribute : global::System.Attribute
    {
        public string Path { get; }

        public FileEmbedAttribute(string path)
        {
            Path = path;
        }
    }

    [global::System.AttributeUsage(global::System.AttributeTargets.Method, AllowMultiple = false)]
    internal sealed class FolderEmbedAttribute : global::System.Attribute
    {
        public string Path { get; private set; }
        public string Filter { get; private set; }
        public global::System.IO.SearchOption Option { get; private set; }
        public PathSeparator Separator { get; private set; }

        public FolderEmbedAttribute(string path, string filter = "*", global::System.IO.SearchOption option = global::System.IO.SearchOption.AllDirectories, PathSeparator separator = PathSeparator.Slash)
        {
            Path = path;
            Filter = filter;
            Option = option;
            Separator = separator;
        }
    }
}
