C# 组件的使用方法示例详解

Stopwatch sw = new Stopwatch();
sw.Start();
// 要执行的代码块
Thread.Sleep(2000);
sw.ElapsedMilliseconds // 消耗时间
Console.WriteLine(sw.ElapsedMilliseconds);

string[] list2 = { "1", "3.14", "OK" };
ListViewItem lt = new ListViewItem(list2[0]);
lt.SubItems.Add(list2[1]);
lt.SubItems.Add(list2[2]);
listView1.BeginInvoke(new Action(() =>
{
    listView1.Items.Add(lt);
    // 显示最下方
    listView1.Items[listView1.Items.Count - 1].EnsureVisible();
}));
