在我的应用程序中，我使用 CodeDom.Compiler 从 source.cs 文件编译另一个程序，并在编译时使用以下方法嵌入一些资源（exe 和 dll 文件）：

 // .... rest of code

if (provider.Supports(GeneratorSupport.Resources))
{
    cp.EmbeddedResources.Add("MyFile.exe");
}
if (provider.Supports(GeneratorSupport.Resources))
{
    cp.EmbeddedResources.Add("New.dll");
}
// ....rest of code

在编译的文件中，我需要将嵌入的资源读取为字节数组。现在我通过使用下面的函数和使用将资源提取到磁盘来做到这一点 

File.ReadAllBytes("extractedfile.exe");
File.ReadAllBytes("extracteddll.dll");

我使用此功能将两个文件提取到磁盘后执行此操作：

public static void ExtractSaveResource(String filename, String location)
{
    //  Assembly assembly = Assembly.GetExecutingAssembly();
    System.Reflection.Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
    // Stream stream = assembly.GetManifestResourceStream("Installer.Properties.mydll.dll"); // or whatever 
    // string my_namespace = a.GetName().Name.ToString();
    Stream resFilestream = a.GetManifestResourceStream(filename);
    if (resFilestream != null)
    {
        BinaryReader br = new BinaryReader(resFilestream);
        FileStream fs = new FileStream(location, FileMode.Create); // say 
        BinaryWriter bw = new BinaryWriter(fs);
        byte[] ba = new byte[resFilestream.Length];
        resFilestream.Read(ba, 0, ba.Length);
        bw.Write(ba);
        br.Close();
        bw.Close();
        resFilestream.Close();
    }
    // this.Close(); 
}

我怎样才能做同样的事情（将嵌入式资源作为字节数组获取）但不向硬盘写入任何内容？

您实际上已经将流读取到字节数组，为什么不停在那里呢？

public static byte[] ExtractResource(String filename)
{
    System.Reflection.Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
    using (Stream resFilestream = a.GetManifestResourceStream(filename))
    {
        if (resFilestream == null) return null;
        byte[] ba = new byte[resFilestream.Length];
        resFilestream.Read(ba, 0, ba.Length);
        return ba;
    }
}

使用 a 的简单替代方法MemoryStream：

var ms = new MemoryStream();
await resFilestream.CopyToAsync(ms);
var bytes = ms.ToArray();

请记住，嵌入式资源文件名 = Assemblyname.fileName

string fileName = "test.pdf";
System.Reflection.Assembly a = System.Reflection.Assembly.GetExecutingAssembly();
string fileName = a.GetName().Name + "." + "test.pdf";

using (Stream resFilestream = a.GetManifestResourceStream(fileName))
{
    if (resFilestream == null) return null;
    byte[] ba = new byte[resFilestream.Length];
    resFilestream.Read(ba, 0, ba.Length);
    var byteArray = ba;
}

如果您正在阅读嵌入式资源，这是一种简单的方法。

string resourcePath = "pack://application:,,,/resource/location/S_2/{0}";
        StreamResourceInfo resInfo = Application.GetResourceStream(new Uri(resourcePath));

        if (resInfo == null)
        {
            throw new Exception("Resource not found: " + resourcePath);
        }

        var ms = new System.IO.MemoryStream();
        await resInfo.Stream.CopyToAsync(ms);
        byte[] bytes = ms.ToArray();

File.WriteAllBytes(@"C:\Users\admin\Desktop\MyFile.exe", Resources.BinFile); // binary file
File.WriteAllText(@"C:\Users\admin\Desktop\text.txt", Resources.TextFile); // text file
