我一直在关注关于嵌入式资源的THIS小教程。它是由Derek Comartin编写的，它处理了将嵌入式资源添加到.csproj文件中的简单操作。

很好。按照他的指示去做了，但是我在resourceStream中得到了null。有几个问题没有将你的资源设置为属性中的“嵌入式资源”，但我做了所有的事情。

以下是资源属性：

我的解决方案有相当多的项目组成，包括一个主项目或启动项目。我想要用作嵌入式资源的资源或JSON文件在初始化项目中，该项目是一个DotNet核心库项目，而不是启动项目。

我遵循了关于查找名称等的建议，使用：

var resourceNames = assembly.GetManifestResourceNames();

这表明它甚至不可用，因此我得到了资源流的"null“。

下面是我访问嵌入式资源的代码。

    public void CATALOGInitialiseSuburbs(CATALOGContext context)
    {
        var assembly = Assembly.GetEntryAssembly();

        var resourceNames = assembly.GetManifestResourceNames();

        var resourceStream = assembly.GetManifestResourceStream("EmbeddedResource.SUBURB.Initialisations.SuburbJSON.australianSuburbs.json");


        using (var reader = new StreamReader(resourceStream, Encoding.UTF8))
        {
            var list = reader.ReadToEndAsync();
        }
    }

下面是我的csproj文件，用于包含嵌入式资源的项目。

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

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <ApplicationIcon />
    <Win32Resource />
  </PropertyGroup>

  <ItemGroup>
    <None Remove="SUBURB.Initialisations\SuburbJSON\australianSuburbs2019-08.json" />
    <None Remove="SUBURB.Initialisations\SuburbJSON\australian_postcodes 2019.csv" />
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Include="SUBURB.Initialisations\SuburbJSON\australianSuburbs2019-08.json" />
    <EmbeddedResource Include="SUBURB.Initialisations\SuburbJSON\australian_postcodes 2019.csv" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\JobsLedger.AUTHORISATION\JobsLedger.AUTHORISATION.csproj" />
    <ProjectReference Include="..\JobsLedger.CATALOG.ENTITIES\JobsLedger.CATALOG.ENTITIES.csproj" />
    <ProjectReference Include="..\JobsLedger.CATALOG\JobsLedger.CATALOG.csproj" />
    <ProjectReference Include="..\JobsLedger.DATA\JobsLedger.DATA.csproj" />
  </ItemGroup>

</Project>

这是我的主项目的csproj文件...

        <ItemGroup>

        </ItemGroup>
    </Target>

</Project>

我非常确定，如果它在主项目中，它会显示出来，但它不在那个项目中。

如何访问子项目(dotnet核心库)中的嵌入式资源？

visual-studio

.net-core

我发现了这个问题，它表明我可以使用类所在的程序集，然后找到该类中资源的名称。

string[] resourceNames = this.GetType().Assembly.GetManifestResourceNames();
foreach(string resourceName in resourceNames)
{
    Console.WriteLine(resourceName);
}

在这一点上，看看它捕获了什么，首先给了我访问这个类所在的程序集的知识，更重要的是，它还列出了我在那里拥有的embeddedResource。

所以，这就是我访问资源的方法。

    var resourceStream = this.GetType().Assembly.GetManifestResourceStream("JobsLedger.INITIALISATION.SUBURB.Initialisations.SuburbJSON.australianSuburbs.json");


    using (var reader = new StreamReader(resourceStream, Encoding.UTF8))
    {
        var list = reader.ReadToEndAsync();
    }
