准备工作
这个窗体继承子基类窗体FrmBase，如果你对FrmBase还不了解，请移步 （十七）c#Winform自定义控件-基类窗体 查看
气泡需要支持多个位置显示，也就是说四面八方都可以显示，并且支持样式，自定义大小，另外具有内置的4中模式（成功，错误，警告，正常）
开始
定义一些枚举
1 public enum TipsSizeMode 2 { 3 Small, 4 Medium, 5 Large, 6 None 7 } 8 public enum TipsState 9 { 10 Default = -1, 11 Success = -6566849, 12 Info = -12477983, 13 Warning = -357816, 14 Error = -1097849 15 }
添加Form，命名FrmTips，继承自FrmBase
属性
1 private ContentAlignment m_showAlign = ContentAlignment.BottomLeft; 2 3 /// <summary> 4 /// 显示位置 5 /// </summary> 6 public ContentAlignment ShowAlign 7 { 8 get { return m_showAlign; } 9 set { m_showAlign = value; } 10 } 11 12 private static List<FrmTips> m_lstTips = new List<FrmTips>(); 13 14 private int m_CloseTime = 0; 15 16 public int CloseTime 17 { 18 get { return m_CloseTime; } 19 set 20 { 21 m_CloseTime = value; 22 if (value > 0) 23 timer1.Interval = value; 24 } 25 }
提供一些公共函数
1 #region 清理提示框 2 /// <summary> 3 /// 功能描述:清理提示框 4 /// 作 者:HZH 5 /// 创建日期:2019-02-28 15:11:03 6 /// 任务编号:POS 7 /// </summary> 8 public static void ClearTips() 9 { 10 for (int i = m_lstTips.Count - 1; i >= 0; i--) 11 { 12 FrmTips current = m_lstTips[i]; 13 if (!current.IsDisposed) 14 { 15 current.Close(); 16 current.Dispose(); 17 } 18 } 19 m_lstTips.Clear(); 20 } 21 #endregion 22 23 /// <summary> 24 /// 重置倒计时 25 /// </summary> 26 public void ResetTimer() 27 { 28 if (m_CloseTime > 0) 29 { 30 timer1.Enabled = false; 31 timer1.Enabled = true; 32 } 33 }

用处及效果
用处：向用户提示一些信息，但是这些信息又不是非常重要，不需要用户确定的时候可以用到这个东西
效果：
调用示例
1 FrmTips.ShowTipsError(this, "Error提示信息"); 2 FrmTips.ShowTipsInfo(this, "Info提示信息"); 3 FrmTips.ShowTipsSuccess(this, "Success提示信息"); 4 FrmTips.ShowTipsWarning(this, "Warning提示信息");
