内存不足的问题

Question

        #region 重绘

        protected override void OnPaint(PaintEventArgs e)
        {
            // try
            {

                Bitmap memBmp = new Bitmap(pCanvas.Width, pCanvas.Height);

                using (Graphics gMem = Graphics.FromImage(memBmp))
                {
                    //  
                    pCanvas.Image = memBmp;
                    WSnap _wSnap = new WSnap(this);
                    Color canvasColor = Color.FromArgb(0xE5, 0xE5, 0xE5);

                    gMem.Clear(canvasColor);

                    Canvas.InitCanvas(gMem, _canvas, pCanvas, _zoom);

                    gMem.DrawImage(memBmp, pCanvas.ClientRectangle.X, pCanvas.ClientRectangle.Y);

                    // 高清,平滑 
                    gMem.SmoothingMode = SmoothingMode.HighQuality;
                    gMem.InterpolationMode = InterpolationMode.HighQualityBicubic;
                    gMem.CompositingQuality = CompositingQuality.HighSpeed;

      

                    _wCmd._wGLine.Draw(gMem, _canvas, this, _wCmd, _drawContainer, this.Font, _zoom);

                    if (IsDrawing)
                    {
                        _wGraph.DrawOnMouse(gMem, _canvas, pCanvas, _wCmd, _drawContainer._dcMouseMovePoint, _zoom);
                    }

                    if (GeneralCmd._gcNewDraw == false)
                    {
                        _wGraph.DrawClickPoint(gMem, _canvas, _wCmd, _drawContainer, _zoom);
                    }

                    if (_lockSnap)
                    {
                        _wSnap.DrawSnap(gMem, _zoom);
                    }

                    using (Graphics gg = pCanvas.CreateGraphics())
                    {
                        gg.DrawImage(memBmp, pCanvas.ClientRectangle.X, pCanvas.ClientRectangle.Y);
                    }
                }
            }
            //catch
            {
            }
        }
        #endregion

我在重绘的地方 就写这些。。里面的实现无关紧要。 我的pCanvas是个画布控件,Bitmap我也尝试过using来释放，可是一释放就出错。。不知道怎么办。。

我在画图的时候就会报内存不足有的时候 又不会报内存不足 不知道为什么。。
