c# - C# 加载原始字节

Question

我开发了一个小型解密和执行应用程序，但我被困在执行部分。我使用以下方法成功执行 .NET 程序集：

 Assembly asm = Assembly.Load(decryptedBytes);   
 if (asm.EntryPoint == null)
     throw new ApplicationException("No entry point found!");

 MethodInfo ePoint = asm.EntryPoint;
 object ins = asm.CreateInstance(ePoint.Name);
 ePoint.Invoke(ins, null);

但是当我尝试使用这篇文章分配一个可执行区域时，应用程序崩溃了

我得到的唯一有用的信息是：

Fault Module Name:  StackHash_0a9e

这是我的代码：

  const uint PAGE_EXECUTE_READWRITE = 0x40;
  const uint MEM_COMMIT = 0x1000;

  [DllImport("kernel32.dll", SetLastError = true)]
  static extern IntPtr VirtualAlloc(IntPtr lpAddress, uint dwSize, uint flAllocationType, uint flProtect);

  private delegate int IntReturner();

IntPtr buf = VirtualAlloc(IntPtr.Zero, (uint)decryptedBytes.Length, MEM_COMMIT, PAGE_EXECUTE_READWRITE);
Marshal.Copy(decryptedBytes, 0, buf, decryptedBytes.Length);

IntReturner ptr = (IntReturner)Marshal.GetDelegateForFunctionPointer(buf, typeof(IntReturner));
Console.WriteLine(ptr());
