怎么使用c进行实时电流测量

在过去，我创建并使用了一个简单的labview VI（后来内置于exe中），它连续采石并在图表上绘制了我用HP66312A电源供电的设备所消耗的电流消耗。
在解决开机故障等问题时，此工具可用于识别问题。附件1是我的Labview程序框图的屏幕截图。
当我运行它时，输出看起来像附加2.我试图将此应用程序转换为纯C＃应用程序。
我能够使用安捷伦命令专家来构建我需要的命令并最终得到这个代码:(不是最优雅的代码，但请耐心等待，因为这是写入/读取电源的第一步）private void button1_Click
（object sender，EventArgs e）{foreach（chart1.Series中的var系列）{series.Points.Clear（）;
双重IMeasure;
int Sample = 0;
int Voltage = Convert.ToInt16（NVoltage.Value）;
int Current = Convert.ToInt16（NCurrent.Value）;
string GPIO = Convert.ToString（NGPIO.Value）;
Ag66xx v6612C =新Ag66xx（“GPIB0 ::”+ GPIO +“:: INSTR”）;
v6612C.SCPI.SOURce.CURRent.LEVel.IMMediate.AMPLitude.Command（Current，“A”）;
v6612C.SCPI.SOURce.VOLTage.LEVel.IMMediate.AMPLitude.Command（Voltage，“V”）;
v6612C.SCPI.OUTPut.STATe.Command（真）;
Ag66xxx v66312A =新Ag66xxx（“GPIB0 :: 1 :: INSTR”）;
Sample = Convert.ToInt16（NSpan.Value）;
for（int i = 1; i {v66312A.SCPI.MEASure.SCALar.CURRent.DC.Query（out IMeasure）; chart1.Series [“Current”]。Points.AddXY（i，IMeasure）;}}它使用了
给定时间由NSpan设置挖掘总线并将其存储在一个数组中然后将结果解析为图形。附件3是我的输出的样子。这很适合记录触发式样分析，但我希望能够做到
这个实时问题。我遇到的问题是我不知道如何使用C＃连续采集电流并按照我使用Labview的方式实时绘制图表。每次我尝试使用while或do循环时
阅读当前，我的程序挂起。任何帮助将不胜感激。谢谢，attach2.png17.0 KBattached3.png49.2 KB

  In the past, I have created and used a simple Labview VI (later built in to an exe) that continuously quarry and chart on a graph the current consumption used by devices I power with my HP66312A power supply.
This tool is useful in identifying an issue when troubleshooting power-on failures etc.  attached1 is a screen shot of the Block diagram of my Labview program. When I run it, the output looks like attached 2.
  
I am trying to convert this application to a pure C# application. I was able to use the Agilent Command Expert to build the commands I needed and ended up with this code:
(not the most elegant code, but bear with me since this is a first pass at writing/reading the power supply)

private void button1_Click(object sender, EventArgs e)
        {
            foreach (var series in chart1.Series)
            {
                series.Points.Clear();
            }
            double IMeasure;
            int Sample = 0;                 
            int Voltage = Convert.ToInt16(NVoltage.Value);
            int Current = Convert.ToInt16(NCurrent.Value);
            string GPIO = Convert.ToString(NGPIO.Value);
            Ag66xx v6612C = new Ag66xx("GPIB0::"+ GPIO +"::INSTR");
            v6612C.SCPI.SOURce.CURRent.LEVel.IMMediate.AMPLitude.Command(Current, "A");
            v6612C.SCPI.SOURce.VOLTage.LEVel.IMMediate.AMPLitude.Command(Voltage, "V");
            v6612C.SCPI.OUTPut.STATe.Command(true);               
            Ag66xxx v66312A = new Ag66xxx("GPIB0::1::INSTR");
            Sample = Convert.ToInt16(NSpan.Value);     
            for (int i = 1; i < Sample; i++)
                {
                    v66312A.SCPI.MEASure.SCALar.CURRent.DC.Query(out IMeasure);
                    chart1.Series["Current"].Points.AddXY(i, IMeasure);
                }
        }

It uses a given time set by NSpan to quarry the bus and store it in an array then it pars the results onto a graph. attached3 is what my output looks like. This works well to record a triggered style analysis, but I want to be able to do this in real time.
  
The problem I have is that I don’t know how to use C# to continuously quarry the current and chart it in real time the way I do using Labview. every time I try to use a while or a do loop to read current, my program hangs.

Any help will be much appreciated.
Thanks,
