在课堂内我有这个方法/功能:

public static void gpuView

在这种方法中,我想要调用此行:

this.Invoke(new Action(() => myData.Add("Gpu Temeprature --- " + sensor.Value.ToString())));

但就此而言,我收到了错误:

  

错误1关键字'this'在静态属性static中无效   方法或静态字段初始化程序

如果我删除静态只使该函数公开然后我在Invoke上获取错误:

  

错误1'HardwareMonitoring.Hardware'不包含定义   对于'调用'而没有扩展方法'调用'接受第一个   可以找到“HardwareMonitoring.Hardware”类型的参数(是吗?   缺少using指令或程序集引用?)

  

错误2非静态字段需要对象引用,   方法或属性'HardwareMonitoring.Hardware.gpuView(bool,   System.Collections.Generic.List,System.Windows.Forms.ListBox,   System.Windows.Forms.Button,float?,System.Windows.Forms.Label)'

DoWork活动:

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            BackgroundWorker worker = sender as BackgroundWorker;
            while (true)
            {
                if ((worker.CancellationPending == true))
                {
                    e.Cancel = true;
                    break;
                }
                else
                {
                    if (tempCpuValue >= (float?)nud1.Value || tempGpuValue >= (float?)nud1.Value)
                    {
                        soundPlay = true;
                        blinking_label();
                        NudgeMe();
                    }
                    else
                    {
                        soundPlay = false;
                        stop_alarm = true;

                    }
                    data = new List<string>();
                    Hardware.cpuView(pauseContinueDoWork, data, listBox1, button1, tempCpuValue);
                    Hardware.gpuView(pauseContinueDoWork, data, listBox1, button1, tempGpuValue, label4);
                    listBox1.DataSource = data;
                    listBox1.Invalidate();

                }

            }
        }

And the two listBox events:

    private void listBox1_MeasureItem(object sender, MeasureItemEventArgs e)
            {
                e.ItemHeight = 21;
            }

            private void listBox1_DrawItem(object sender, DrawItemEventArgs e)

                }
                else
                {

                    ColorText.ColorListBox(data, e);

                }
            }

And the ColorText class:


    using System;

                box.SelectionLength = 0;

                box.SelectionColor = color;
                box.AppendText(text);
                box.SelectionColor = box.ForeColor;
            }

            public static void ColorListBox(List<string> data, DrawItemEventArgs e)
            {
                string strLeft = null;
                string strMid = "---";
                string strRight = null;

                    strLeft = data[e.Index].Substring(0, index);
                    strRight = data[e.Index].Substring(index + strMid.Length);
                }

                using (Font f = new Font(FontFamily.GenericSansSerif, 16, FontStyle.Regular))
                {
                    float startPos;
                    e.Graphics.DrawString(strLeft, f, Brushes.Red, e.Bounds.X, e.Bounds.Y);
                    startPos = e.Graphics.MeasureString(strLeft, f).Width;
                    e.Graphics.DrawString(strMid, f, Brushes.Black, e.Bounds.X + startPos, e.Bounds.Y);
                    startPos = e.Graphics.MeasureString(strLeft + strMid, f).Width;
                    e.Graphics.DrawString(strRight, f, Brushes.Green, e.Bounds.X + startPos, e.Bounds.Y);
                }
            }
        }
    }

在Form1加载事件中我做了:

h = new Hardware(this);
backgroundWorker1.RunWorkerAsync();
