Dotnet CORE 3.1 - 访问关联项目库中的嵌入式资源（文件）

Question

我一直在关注这个关于嵌入式资源的小教程。它由 Derek Comartin 编写，处理将嵌入资源添加到 .csproj 文件的简单操作。

美好的。按照他的指示做了，但是我在资源流中得到了空值。有几个问题没有在属性等中将您的资源设置为“嵌入资源”，但我做到了所有这些。

以下是资源属性：

我的解决方案有很多项目组成，包括主项目或启动项目。我想用作嵌入式资源的资源或 JSON 文件位于 Initialisation 项目中，该项目是一个 DotNet Core 库项目，而不是启动项目。

我遵循有关使用以下方法查找名称等的建议：

var resourceNames = assembly.GetManifestResourceNames();

这表明它甚至不可用，因此我得到了资源流的“空”。

这是我访问嵌入资源的代码。

    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();
        }
    }

这是具有嵌入资源的项目的 csproj 文件。

我很确定它会出现在主项目中，但它不在那个项目中。

如何访问作为子项目（dotnet 核心库）中的嵌入资源的嵌入资源？

Answer 1

我发现这个问题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);
}

在这一点上进行并查看它捕获的内容首先让我知道我正在访问这个类所在的程序集，更重要的是它还列出了我在那里拥有的内嵌资源。

所以，这就是我访问资源时所做的。

    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();
    }

请注意，第一次尝试为我提供了嵌入资源所在的完整路径。我用它来创建位置，正确的组装使我找到了资源。
