类的，我有这个方法/函数内部：
公共静态无效gpuView
而且在这个方法中，我有这行至极我想要调用：
this.Invoke(new Action(() => myData.Add("Gpu Temeprature --- " + sensor.Value.ToString())));
但在这个即时得到错误：
Error 1 Keyword 'this' is not valid in a static property, static method, or static field initializer
如果我删除静态只能使则函数公共IM才能上调用错误：
Error 1 'HardwareMonitoring.Hardware' does not contain a definition for 'Invoke' and no extension method 'Invoke' accepting a first argument of type 'HardwareMonitoring.Hardware' could be found (are you missing a using directive or an assembly reference?)
而且
Error 2 An object reference is required for the non-static field, method, or property 'HardwareMonitoring.Hardware.gpuView(bool, System.Collections.Generic.List, System.Windows.Forms.ListBox, System.Windows.Forms.Button, float?, System.Windows.Forms.Label)'
DoWork的事件：
私人无效backgroundWorker1_DoWork（对象发送者，DoWorkEventArgs e） {BackgroundWorker worker = sender作为BackgroundWorker; （（worker.CancellationPending == true）） while（true） { e.Cancel = true; 休息; } 别的 { 如果（tempCpuValue> =（浮动）nud1.Value || tempGpuValue> =（浮动）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();
}
}
}
而且，这两个列表框事件：
private void listBox1_MeasureItem(object sender, MeasureItemEventArgs e)
{
e.ItemHeight = 21;
}
private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
if (e.Index == -1)
{
}
else
{
ColorText.ColorListBox(data, e);
}
}
而且ColorText类：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.Windows.Forms;
namespace GatherLinks
{
class ColorText
{
public static void Texts(RichTextBox box, string text, Color color)
{
box.SelectionStart = box.TextLength;
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;
if (data[e.Index].Contains(strMid))
{
int index = data[e.Index].IndexOf(strMid);
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);
}
}
}
}
而且在Form1的加载事件我所做的：
h = new Hardware(this);
backgroundWorker1.RunWorkerAsync();
你打算调用什么'Invoke（）'函数？ – bmm6o 2013-03-09 20:00:26
'this.Invoke'看起来像用于切换到UI线程的winforms-API;你想做什么？为什么你需要切换到UI线程？由于你有一些控制实例，你可以使用它们...'lb1.Invoke（...）' – 2013-03-09 20:01:09
我试图更新Form1中的listBox1。 https://www.dropbox.com/s/dtdqnpemwistz5n/HardwareMonitoring.rar这是我的项目，也许有人可以看看我在Form1中的背景工作的一部分，我尝试了很多次，不能使它工作。我在Form1中使用backgroundworker，并在这里调用这个类的函数来更新Form1中的listBox1，我想每秒更新一次listBox。但我无法弄清楚如何使用MSDN文档中的示例尝试使用backgroundworker到目前为止没有什么效果。 – user2065612 2013-03-09 20:03:52
