访问类值并在Form1.cs中使用它

Question

我试图从类中访问一个值，并在form1.cs文件的循环中使用该值，但是每次运行程序时，该值似乎都不会传递。我连接了需要一定电压的硬件DAC，并且试图将其返回到一个叫做CountValue的变量中。但是，当我设置while循环只是为了测试并查看该值是否实际传递时，该循环将不起作用。这是我尝试过的：

//Form1.cs code
private void AdjustLaser()
        {


            double intensity;

            while (labjackT4.CountValue < 2000)

            labjackT4.ConvertFromDAC();
            if (labjackT4.CountValue > 500)
            {
                intensity = 0.3;
                laser.setLdCurrSetpoint(intensity);
            }
            else
            {
                //intensity = 0.2;
                //laser.setLdCurrSetpoint(intensity);
            }
        }

//labjackT4.cs class code
public LabJackT4()
        {
            //Set Default Value
            this.CountValue = 0;
        }
