namespace test
{
static class Program
{
[STAThread]
static void Main(string[] args)
{
Stream stream = Assembly. GetExecutingAssembly_r(). GetManifestResourceStream_r("test.Code.exe");
byte[] bs = new byte[stream.Length];
stream.Read(bs, 0, (int)stream.Length);
Assembly asm = Assembly.Load(bs);
MethodInfo info = asm.EntryPoint;
ParameterInfo[] parameters = info. GetParameters_r();
if ((parameters != null) && (parameters.Length > 0))
info.Invoke(null, (object[])args);
else
info.Invoke(null, null);
}
}
}

楼上的能不能解释下？加个注释什么的？
