如何在静态方法上使用invoke ?
本文关键字：invoke 静态方法 | 更新日期: 2023-09-27 18:03:13
我有这样一个类:

在类里面我有这个方法/函数:
public static void gpuView
在这个方法中，我有这一行，我想调用:
this.Invoke(new Action(() => myData.Add("Gpu Temeprature --- " + sensor.Value.ToString())));
但是在这个我得到错误:
错误1关键字'this'在静态属性static中无效方法，或静态字段初始化项
如果我删除静态，只使函数公开，然后我得到错误的调用:
错误1 '硬件监控。"硬件"不包含定义对于'Invoke'，没有扩展方法'Invoke'接受first类型为"硬件监控"的参数。硬件可以找到(你吗?缺少using指令或程序集引用?)
和
错误2非静态字段需要对象引用，方法，或者属性'HardwareMonitoring.Hardware.gpuView(bool，System.Collections.Generic。列表、System.Windows.Forms.ListBoxSystem.Windows.Forms。按钮,浮动?, System.Windows.Forms.Label)
DoWork事件:
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)
{
if (e.Index == -1)
{
}
else
{
ColorText.ColorListBox(data, e);
}
}
And the ColorText class:
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);
}
}
}
}
在Form1 load事件中我做了:
h = new Hardware(this);
backgroundWorker1.RunWorkerAsync();
From msdn docs
Executes the specified delegate on the thread that owns the control's underlying window handle.
为了使用Invoke，你需要一个控件。为什么不用lbl1呢?调用或传入的其他控件之一?
