Run Exe file as an Embedded Resource in C#

1. First add the embeded executable file as resource file to your existing resource file, if you dont have one, then you need to [add existing item to your project, and select resource file]
2. When you add the executable file in resource editor page, select type as [Files], then find your embeded excutable file and add it. For example the file named as "subexe.exe", then the resource design cs file will have following code added:
   

   internal static byte[] SubExe {
           get {
               object obj = ResourceManager.GetObject("SubExe", resourceCulture);
               return ((byte[])(obj));
           }
       }
   

3. add a method to access to your resource, which is also very simple, just add following code to your resource designer cs file

   
   public static byte[] GetSubExe()
       {
           return SubExe;
       }
   

4. In your main executable source code, add following to read resource and write it to a new file

   
   string tempExeName = Path.Combine(Directory.GetCurrentDirectory(), "A3E5.exe");
   
       using(FileStream fsDst = new FileStream(tempExeName,FileMode.CreateNew,FileAccess.Write))
       {
           byte[] bytes = Resource1.GetSubExe();
   
           fsDst.Write(bytes, 0, bytes.Length);
       }    
   
   
   

5. Use process to run the new executable file

One could write a simpler

private void ExtractResource(string resName, string fName)
 {
      object ob = Properties.Resources.ResourceManager.GetObject(resName, originalCulture);
      byte[] myResBytes = (byte[])ob;
      using (FileStream fsDst = new FileStream(fName, FileMode.CreateNew, FileAccess.Write))
      {
         byte[] bytes = myResBytes;
         fsDst.Write(bytes, 0, bytes.Length);
         fsDst.Close();
         fsDst.Dispose();
      }
}
