我制作的ac＃项目列出了ListViews中的某些内容，但是ListViews有点烦人，他们每次都不工作，有时候输入是正确的，可以显示在MessageBox或ListBox，但尝试将其添加到ListBox时没有任何反应，这是我的代码，按下按钮时没有任何反应。
private async void button2_Click(object sender, EventArgs e)
{
if(shouldirefresh == true)
{
button2.Enabled = false;
checkBox1.Enabled = false;
checkBox2.Enabled = false;
checkBox3.Enabled = false;
checkBox4.Enabled = false;
checkBox5.Enabled = false;
checkBox6.Enabled = false;
pictureBox1.Visible = true;
webBrowser1.Refresh();
await td(3500);
}
checkBox1.Text = "Highlight -50%";
checkBox2.Text = "Highlight 100%";
checkBox3.Text = "Highlight 50%";
pictureBox1.Visible = true;
min50 = 0;
max100 = 0;
eq50 = 0;
listView1.Items.Clear();
listBox1.Items.Clear(); listBox2.Items.Clear(); listBox3.Items.Clear(); listBox4.Items.Clear();
lsttit.Clear(); lstpoint.Clear(); lstmaxwosl.Clear(); lstmax.Clear();
HtmlDocument doc = this.webBrowser1.Document;
doc = webBrowser1.Document;
var links = PulseVar.myrodoc.GetElementsByTagName("td");
foreach (HtmlElement link in links)
{
if (link.GetAttribute("className") == "title")
{
lsttit.Add(link.InnerText);
}
else if (link.GetAttribute("className") == "point" || link.GetAttribute("className") == "point tekort")
{
lstpoint.Add(link.InnerText);
}
else if (link.GetAttribute("className") == "max" || link.GetAttribute("className") == "max tekort")
{
string RM = link.InnerText.Remove(0, 1);
lstmax.Add(RM);
}
else if (link.GetAttribute("className") == "date")
{
datez.Add(link.InnerText);
}
else if(link.GetAttribute("className") == "average")
{
lstav.Add(link.InnerText);
}
else if(link.GetAttribute("className") == "comment")
{
if(link.InnerText == " ")
{
lstcomment.Add(" ");
}
else
{
lstcomment.Add(link.InnerText);
}
}
else if(link.GetAttribute("className") == "TeacherTitle")
{
this.Text = "Myro ~ " + link.InnerText;
}
}
for (int i = 0; i <= lsttit.Count - 1; i++)
{
ListViewItem d = new ListViewItem(lsttit[i]);
try
{
if (decimal.Parse(lstpoint[i]) < (decimal.Parse(lstmax[i]) / 2))
{
min50++;
d.SubItems.Add(lstpoint[i] + "/" + lstmax[i]);
if (checkBox1.Checked == true)
{
d.ForeColor = Color.Red;
}
}
else if (decimal.Parse(lstpoint[i]) == (decimal.Parse(lstmax[i])))
{
//listView2.Items.Add(lstpoint[i] + "/" + lstmax[i]);
d.SubItems.Add(lstpoint[i] + "/" + lstmax[i]);
if (checkBox2.Checked == true)
{
d.ForeColor = Color.Green;
}
max100++;
}
else if (decimal.Parse(lstpoint[i]) == (decimal.Parse(lstmax[i]) / 2))
{
//listView2.Items.Add(lstpoint[i] + "/" + lstmax[i]);
d.SubItems.Add(lstpoint[i] + "/" + lstmax[i]);
if (checkBox3.Checked == true)
{
d.ForeColor = Color.Yellow;
}
eq50++;
}
else
{
d.SubItems.Add(lstpoint[i] + "/" + lstmax[i]);
//listView2.Items.Add(lstpoint[i] + "/" + lstmax[i]);
}
}
catch (Exception)
{
//listView2.Items.Add(lstpoint[i] + "/" + lstmax[i]);
d.SubItems.Add(lstpoint[i] + "/" + lstmax[i]);
}
d.SubItems.Add(datez[i]);
d.SubItems.Add(lstav[i] + "/" + lstmax[i]);
d.SubItems.Add(lstcomment[i]);
listView1.Items.Add(d);
}
checkBox1.Text += "(" + min50.ToString() + ")";
checkBox2.Text += "(" + max100.ToString() + ")";
checkBox3.Text += "(" + eq50.ToString() + ")";
pictureBox1.Visible = false;
//groupBox1.Location = new Point(12, 12);
checkBox5.Checked = false;
button2.Enabled = true;
checkBox1.Enabled = true;
checkBox2.Enabled = true;
checkBox3.Enabled = true;
checkBox4.Enabled = true;
checkBox5.Enabled = true;
checkBox6.Enabled = true;
shouldirefresh = true;
label3.Text = DateTime.Now.ToString("dd/MM/yyyy hh:mm");
}
如果我MessageBox.Show(lsttit[i]);它每次都显示正确的数据，我的ListView会有正确的列，并设置为详细信息，但根本没有任何事情发生....
这里有什么问题？
