c# winform 显示一个 tip
public void showTip(string text, int duration = 2000) { var form = new Form { Size = new Size(1, 1), StartPosition = FormStartPosition.CenterScreen }; var tooltip = new System.Windows.Forms.ToolTip(); form.Opacity = 0; form.TopMost = true; form.Show(); tooltip.Show(text, form, new Point(0, 0)); Task.Factory.StartNew(() => { System.Threading.Thread.Sleep(duration); form.Invoke(new MethodInvoker(delegate () { form.Close(); })); }); }
桂棹兮兰桨，击空明兮溯流光。
