实现效果：
知识运用
ListView控件的GridLines //设置是否在ListView控件中显示网格线
public bool GridLines{get;set}
和CheckBoxes属性 //设置listView控件中各数据项是否显示复选框
public bool CheckBoxes{get;set}
以及ListViewItem数据项的Checked属性 //判断是否选中此数据项中的复选框
public bool Checked{get;set}
实现代码：
private void Form1_Load(object sender, EventArgs e)
{
listView1.CheckBoxes = true;
listView1.GridLines = true;
listView1.View = View.Details;
listView1.Columns.Add("文件名称",180,HorizontalAlignment.Left);
listView1.Columns.Add("修改日期",217,HorizontalAlignment.Left);
foreach (string fileName in Directory.GetFiles("C:\\windows\\")) {
FileInfo file = new FileInfo(fileName);
ListViewItem OptionItem = new ListViewItem(file.Name);
OptionItem.SubItems.Add(file.LastWriteTime.ToString());
listView1.Items.Add(OptionItem);
}
}
private void button1_Click(object sender, EventArgs e)
{
foreach (ListViewItem lvi in listView1.Items) {
if(lvi.Checked==false)
lvi.Checked = true;
else
lvi.Checked = false;
}
}
private void button2_Click(object sender, EventArgs e)
{
listView1.Items.Clear();
}
