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。

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!");
   }

我很恼火，你必须在字符串中始终包含名称空间和文件夹。我想简化对嵌入式资源的访问。这就是我写这个小课堂的原因。欢迎使用和改进！

用法：

using(Stream stream = EmbeddedResources.ExecutingResources.GetStream("filename.txt"))
{
 //...
}

类别：

public class EmbeddedResources
{
    private static readonly Lazy<EmbeddedResources> _callingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetCallingAssembly()));

    private static readonly Lazy<EmbeddedResources> _entryResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetEntryAssembly()));

    private static readonly Lazy<EmbeddedResources> _executingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetExecutingAssembly()));

    private readonly Assembly _assembly;

    private readonly string[] _resources;

    public EmbeddedResources(Assembly assembly)
    {
        _assembly = assembly;
        _resources = assembly.GetManifestResourceNames();
    }

    public static EmbeddedResources CallingResources => _callingResources.Value;

    public static EmbeddedResources EntryResources => _entryResources.Value;

    public static EmbeddedResources ExecutingResources => _executingResources.Value;

    public Stream GetStream(string resName) => _assembly.GetManifestResourceStream(_resources.Single(s => s.Contains(resName)));

}

阅读了这里张贴的所有解决方案后。我就是这样解决的：

// How to embedded a "Text file" inside of a C# project
//   and read it as a resource from c# code:
//
// (1) Add Text File to Project.  example: 'myfile.txt'
//
// (2) Change Text File Properties:
//      Build-action: EmbeddedResource
//      Logical-name: myfile.txt      
//          (note only 1 dot permitted in filename)
//
// (3) from c# get the string for the entire embedded file as follows:
//
//     string myfile = GetEmbeddedResourceFile("myfile.txt");

public static string GetEmbeddedResourceFile(string filename) {
    var a = System.Reflection.Assembly.GetExecutingAssembly();
    using (var s = a.GetManifestResourceStream(filename))
    using (var r = new System.IO.StreamReader(s))
    {
        string result = r.ReadToEnd();
        return result;
    }
    return "";      
}

这是一个类，您可能会发现从当前程序集读取嵌入式资源文件非常方便：

using System.IO;
using System.Linq;
using System.Text;
using System.Reflection;

public static class EmbeddedResourceUtils
{
    public static string ReadFromResourceFile(string endingFileName)
    {
        var assembly = Assembly.GetExecutingAssembly();
        var manifestResourceNames = assembly.GetManifestResourceNames();

        foreach (var resourceName in manifestResourceNames)
        {
            var fileNameFromResourceName = _GetFileNameFromResourceName(resourceName);
            if (!fileNameFromResourceName.EndsWith(endingFileName))
            {
                continue;
            }

            using (var manifestResourceStream = assembly.GetManifestResourceStream(resourceName))
            {
                if (manifestResourceStream == null)
                {
                    continue;
                }

                using (var streamReader = new StreamReader(manifestResourceStream))
                {
                    return streamReader.ReadToEnd();
                }
            }
        }

        return null;
    }
    
    // https://stackoverflow.com/a/32176198/3764804
    private static string _GetFileNameFromResourceName(string resourceName)
    {
        var stringBuilder = new StringBuilder();
        var escapeDot = false;
        var haveExtension = false;

        for (var resourceNameIndex = resourceName.Length - 1;
            resourceNameIndex >= 0;
            resourceNameIndex--)
        {
            if (resourceName[resourceNameIndex] == '_')
            {
                escapeDot = true;
                continue;
            }

            if (resourceName[resourceNameIndex] == '.')
            {
                if (!escapeDot)
                {
                    if (haveExtension)
                    {
                        stringBuilder.Append('\\');
                        continue;
                    }

                    haveExtension = true;
                }
            }
            else
            {
                escapeDot = false;
            }

            stringBuilder.Append(resourceName[resourceNameIndex]);
        }

        var fileName = Path.GetDirectoryName(stringBuilder.ToString());
        return fileName == null ? null : new string(fileName.Reverse().ToArray());
    }
}
