C#3.5

I have a Project in C# 2015 Community edition, I have enbedded a dll as an embedded resource, I copy it into disk and after to memory stream how can I Access it from memory as a file and delete it from disk so the user cannot open or move it (while in memory and not on disk)

private void button5_Click(object sender, EventArgs e)
        {
        
            CopyResource("injector.Aimware.dll", "Aimware4.dll");
            string path = "Aimware4.dll";
            //system.MemStream.Read()
            File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden);
            using (FileStream fileStream = File.OpenRead(path))
            {
                MemoryStream memStream = new MemoryStream();
                memStream.SetLength(fileStream.Length);
                fileStream.Read(memStream.GetBuffer(), 0, (int)fileStream.Length);
            }
            Process proc1 = Process.GetProcessesByName("csgo")[0];
              
                    HVInjector.inject(@"c:\Aimware4.dll", proc1);
             

            
        }

Sorry little NEW to memory coding

What I have tried:

Works from embedded resource to Copy to disk with this function
private void CopyResource(string resourceName, string file)
{
using (Stream resource = GetType().Assembly.GetManifestResourceStream(resourceName))
{
if (resource == null)
{
throw new ArgumentException("No such resource", "resourceName");
}
using (Stream output = File.OpenWrite(file))
{
resource.CopyTo(output);
}
}
}
