使用Native Dll将C#解决方案部署到单个EXE中

Question

我有AC#Vi​​sual Studio 2012解决方案,它依赖于我使用PInvoke访问的本机DLL.部署应用程序时,我必须确保此Dll位于app文件夹中.

无论如何我可以将这个Dll合并到可执行文件中吗？

也许作为一种资源？

我听说过ILMerge,但我被告知它无法应对本机代码.

任何帮助,将不胜感激.

您可以使用Visual Studio 创建一个安装程序包项目,将所有文件部署到正确的位置或使用其他第三方打包软件(如完整的InstallShield或替代品)

但是,您的问题提醒我在Open Hardware Monitor项目中,它们将驱动程序包含为嵌入式资源,并在用户启动应用程序时将其解压缩.它的工作原理是这样的:他们已经加入WinRing0.sys,并WinRing0x64.sys到项目并设置其生成操作,以嵌入的资源,那么他们必须提取从资源驱动器的方法:

private static bool ExtractDriver(string fileName) {
  string resourceName = "OpenHardwareMonitor.Hardware." +
    (OperatingSystem.Is64BitOperatingSystem() ? "WinRing0x64.sys" : 
    "WinRing0.sys");

  string[] names =
    Assembly.GetExecutingAssembly().GetManifestResourceNames();
  byte[] buffer = null;
  for (int i = 0; i < names.Length; i++) {
    if (names[i].Replace('\\', '.') == resourceName) {
      using (Stream stream = Assembly.GetExecutingAssembly().
        GetManifestResourceStream(names[i])) 
      {
          buffer = new byte[stream.Length];
          stream.Read(buffer, 0, buffer.Length);
      }
    }
  }

  if (buffer == null)
    return false;

  try {
    using (FileStream target = new FileStream(fileName, FileMode.Create)) {
      target.Write(buffer, 0, buffer.Length);
      target.Flush();
    }
  } catch (IOException) { 
    // for example there is not enough space on the disk
    return false; 
  }

  // make sure the file is actually writen to the file system
  for (int i = 0; i < 20; i++) {
    try {
      if (File.Exists(fileName) &&
        new FileInfo(fileName).Length == buffer.Length) 
      {
        return true;
      }
      Thread.Sleep(100);
    } catch (IOException) {
      Thread.Sleep(10);
    }
  }

  // file still has not the right size, something is wrong
  return false;
}

他们将资源读入缓冲区,将该缓冲区写入磁盘并等待文件刷新到磁盘.
