我们知道在c#里添加图标最常用的方法是使用ImageList，但要读取的程序图标是动态的，那么就需要动态的获得文件的图标
在网上找了找，发现有一个类，直接使用就可以了
贴出来和大家共享，本人在写一个类似于360safe的东西，不过软件增加了更多的个人色彩，希望大家能多多交流！

使用：
把它添加到ListView中
1private void btnRunSearch_Click(object sender, EventArgs e)
2 {
3 try
4 {
5 ListViewItem lvi;
6 ListViewItem.ListViewSubItem lvsi;
7 showSystemIcon showIcon = new showSystemIcon();
8
9 this.lvStartupFileList.Items.Clear();
10 lvStartupFileList.BeginUpdate();
11 foreach (string str in RegistryOperate.strRunRegistry())
12 {
13 string str1 = RegistryOperate.returnRun().GetValue(str).ToString();
14 showIcon.ListViewSysImages(lvStartupFileList);
15 lvi = new ListViewItem();
16 lvi.Text = str;
17 lvi.ImageIndex = showIcon.FileIconIndex(str1);
18 lvsi = new ListViewItem.ListViewSubItem();
19 lvsi.Text = str1;
20 lvi.SubItems.Add(lvsi);
21 lvStartupFileList.Items.Add(lvi);
22 }
23 lvStartupFileList.EndUpdate();
24 }
25 catch
26 {
27 MessageBox.Show(e.ToString());
28 }
