基本上，您使用System.Reflection获取对当前程序集的引用。然后，使用GetManifestResourceStream（）。

例如，从我发布的页面：

注：需要添加使用System.Reflection；让它发挥作用

   Assembly _assembly;
   StreamReader _textStreamReader;

   try
   {
      _assembly = Assembly.GetExecutingAssembly();
      _textStreamReader = new StreamReader(_assembly.GetManifestResourceStream("MyNamespace.MyTextFile.txt"));
   }
   catch
   {
      MessageBox.Show("Error accessing resources!");
   }

通过您的所有能力，我使用这个助手类以通用方式从任何程序集和任何命名空间读取资源。

public class ResourceReader
{
    public static IEnumerable<string> FindEmbededResources<TAssembly>(Func<string, bool> predicate)
    {
        if (predicate == null) throw new ArgumentNullException(nameof(predicate));

        return
            GetEmbededResourceNames<TAssembly>()
                .Where(predicate)
                .Select(name => ReadEmbededResource(typeof(TAssembly), name))
                .Where(x => !string.IsNullOrEmpty(x));
    }

    public static IEnumerable<string> GetEmbededResourceNames<TAssembly>()
    {
        var assembly = Assembly.GetAssembly(typeof(TAssembly));
        return assembly.GetManifestResourceNames();
    }

    public static string ReadEmbededResource<TAssembly, TNamespace>(string name)
    {
        if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));
        return ReadEmbededResource(typeof(TAssembly), typeof(TNamespace), name);
    }

    public static string ReadEmbededResource(Type assemblyType, Type namespaceType, string name)
    {
        if (assemblyType == null) throw new ArgumentNullException(nameof(assemblyType));
        if (namespaceType == null) throw new ArgumentNullException(nameof(namespaceType));
        if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));

        return ReadEmbededResource(assemblyType, $"{namespaceType.Namespace}.{name}");
    }

    public static string ReadEmbededResource(Type assemblyType, string name)
    {
        if (assemblyType == null) throw new ArgumentNullException(nameof(assemblyType));
        if (string.IsNullOrEmpty(name)) throw new ArgumentNullException(nameof(name));

        var assembly = Assembly.GetAssembly(assemblyType);
        using (var resourceStream = assembly.GetManifestResourceStream(name))
        {
            if (resourceStream == null) return null;
            using (var streamReader = new StreamReader(resourceStream))
            {
                return streamReader.ReadToEnd();
            }
        }
    }
}

当您将文件添加到资源中时，您应该将其“访问修改器”选择为“公共”，然后再进行如下操作。

byte[] clistAsByteArray = Properties.Resources.CLIST01;

CLIST01是嵌入文件的名称。

实际上，您可以访问resources.Designer.cs，查看getter的名称。

可以使用Assembly.GetManifestResourceStream方法：

添加以下用法使用System.IO；使用System.Reflection；设置相关文件的属性：具有值Embedded Resource的参数生成操作使用以下代码var assembly=assembly.GetExecutingAssembly（）；var resourceName=“MyCompany.MyProduct.MyFile.txt”；使用（流流=程序集.GetManifestResourceStream（resourceName））使用（StreamReader读取器=新StreamReader（流））{string result=reader.ReadToEnd（）；}resourceName是程序集中嵌入的资源之一的名称。例如，如果嵌入了一个名为“MyFile.txt”的文本文件，该文件位于默认名称为“MyCompany.MyProduct”的项目根目录中，则resourceName为“MyCompany.MyProduct.MyFile.txt”。可以使用assembly.GetManifestResourceNames方法获取程序集中所有资源的列表。

只从文件名中获取resourceName（通过传递名称空间）是一个非常明智的做法：

string resourceName = assembly.GetManifestResourceNames()
  .Single(str => str.EndsWith("YourFileName.txt"));

完整示例：

public string ReadResource(string name)
{
    // Determine path
    var assembly = Assembly.GetExecutingAssembly();
    string resourcePath = name;
    // Format: "{Namespace}.{Folder}.{filename}.{Extension}"
    if (!name.StartsWith(nameof(SignificantDrawerCompiler)))
    {
        resourcePath = assembly.GetManifestResourceNames()
            .Single(str => str.EndsWith(name));
    }

    using (Stream stream = assembly.GetManifestResourceStream(resourcePath))
    using (StreamReader reader = new StreamReader(stream))
    {
        return reader.ReadToEnd();
    }
}

或作为异步扩展方法：

internal static class AssemblyExtensions
{
    public static async Task<string> ReadResourceAsync(this Assembly assembly, string name)
    {
        // Determine path
        string resourcePath = name;
        // Format: "{Namespace}.{Folder}.{filename}.{Extension}"
        if (!name.StartsWith(nameof(SignificantDrawerCompiler)))
        {
            resourcePath = assembly.GetManifestResourceNames()
                .Single(str => str.EndsWith(name));
        }

        using Stream stream = assembly.GetManifestResourceStream(resourcePath)!;
        using StreamReader reader = new(stream);
        return await reader.ReadToEndAsync();
    }
}

// Usage
string resourceText = await Assembly.GetExecutingAssembly().ReadResourceAsync("myResourceName");

我想将嵌入式资源作为字节数组读取（不考虑任何特定编码），最后我使用了MemoryStream，这使得它非常简单：

using var resStream = assembly.GetManifestResourceStream(GetType(), "file.txt");
var ms = new MemoryStream();
await resStream .CopyToAsync(ms);
var bytes = ms.ToArray();

如SonarCloud所示，更好的做法是：

public class Example
{
    public static void Main()
    { 
        // Compliant: type of the current class
        Assembly assembly = typeof(Example).Assembly; 
        Console.WriteLine("Assembly name: {0}", assem.FullName);

        // Non-compliant
        Assembly assembly = Assembly.GetExecutingAssembly();
        Console.WriteLine("Assembly name: {0}", assem.FullName);
    }
}
