尝试读取或写入受保护的内存。这通常指示其他内存已损坏。

Question

        private EventHandler EventAnimator
        {
            get
            {
                if (_eventAnimator == null)
                    _eventAnimator = delegate(object sender, EventArgs e)
                    {
                      Invalidate(ImageRectangle);  //尝试读取或写入受保护的内存。这通常指示其他内存已损坏。
                    };
                return _eventAnimator;
            }
        }
求高人指点迷津。

Answer 1

        public void InsertControl(Control control)
        {
            if (control != null)
            {
                ILockBytes bytes;
                IStorage storage;
                IOleClientSite site;
                Guid guid = Marshal.GenerateGuidForType(control.GetType());
                NativeMethods.CreateILockBytesOnHGlobal(IntPtr.Zero, true, out bytes);
                NativeMethods.StgCreateDocfileOnILockBytes(bytes, 0x1012, 0, out storage);
                IRichEditOle.GetClientSite(out site);//问题所在
                REOBJECT lpreobject = new REOBJECT();
                lpreobject.cp = _richEdit.TextLength;
                lpreobject.clsid = guid;
                lpreobject.pstg = storage;
                lpreobject.poleobj = Marshal.GetIUnknownForObject(control);
                lpreobject.polesite = site;
                lpreobject.dvAspect = 1;
                lpreobject.dwFlags = 2;
                lpreobject.dwUser = 1;
                IRichEditOle.InsertObject(lpreobject);
                Marshal.ReleaseComObject(bytes);
                Marshal.ReleaseComObject(site);
                Marshal.ReleaseComObject(storage);
            }
        }
求高人赐教是不是invalidate()方法读取byte越界了

Answer 2

Guid guid = Marshal.GenerateGuidForType(control.GetType());
  NativeMethods.CreateILockBytesOnHGlobal(IntPtr.Zero, true, out bytes);
  NativeMethods.StgCreateDocfileOnILockBytes(bytes, 0x1012, 0, out storage);
问题都基本存在,
1.重新编译一下试试,
2.用了线程,lock公用的变量
3.外部资源有否正确释放,如:网络,IO ,  要close
4.注意static变量使用
