Question

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命令嵌入一些资源（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

在编译文件中，我需要将嵌入资源作为字节数组读取。现在我通过使用下面的函数和使用

将资源提取到磁盘来实现这一点

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

我使用此函数将两个文件解压缩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（将嵌入资源作为字节数组获取）但不向硬盘写任何内容？

Answer 1

您实际上已经将流读取到字节数组，为什么不停在那里？

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MemoryStream的简单替代方法：

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

Answer 3

 Keep in mind that Embedded resource filename = 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;
        }`

Answer 4

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

如何将嵌入式资源作为字节数组读取而不将其写入磁盘？
