悬赏园豆:10 [待解决问题]

求大神指导,小弟菜鸟一只,我最近写了段代码,通过动态链接库的类中的方法读取两组数据,每组的长度为2048,使用委托刷新窗体控件,结果界面非常卡,求大神指点代码:

 #region 建立委托

        public delegate void SetTchartValue(AxTeeChart.AxTChart chart, double[] wavelength, double[] spectraData);

            tooltxtIntergrationTime.Text = (SpectraSuitInfo.spectraSuitInfoInstance.intergrationTime/1000 ).ToString();
            setTchartValue = new SetTchartValue(SetTchartValues);
            SpectraDataInvokeDelegate = new InvokeDelegate(GetSpecstra);
        }

问题补充:

经过测试是这段代码的问题

SpectraSuitInfo.spectraSuitInfoInstance.spectraData = (double[])Wrapper.getSpectrum(0);
    if (SpectraSuitInfo.spectraSuitInfoInstance.waveLength == null)
  {
SpectraSuitInfo.spectraSuitInfoInstance.waveLength = (double[])                   Wrapper.getWavelengths(0);
   }

Wrapper是外部的动态链接库其中一个类的实例化。不是自己写的,用的别人的。没有源代码。

注意代码排版,这样看着很晕啊~

能留下个您的邮箱吗?我可以把源代码给您发过去

尽量写成后台进程,可THREAD 和 backgroudworker都行 你可以看看

繁花秋水 | 园豆:202 (菜鸟二级) | 2013-07-08 16:28

已经写到后台了

 _thread = new Thread(new ThreadStart(GetSpecstra));
            SpectraSuitInfo.spectraSuitInfoInstance.isForm = true;
            _thread.Start();
            _thread.IsBackground = true;   

请问您看这样写对吗?

GetSpecstra与 ui赋值 在后台进程中调用就可以了

@大笨鹰: 是的 如果还慢的话就在backgroundwork中调用这个线程 UI上基本感觉不到计算的延时

敢问楼主使用的正版还是破解的,还是侦办的好用,厂商有个年末优惠
