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 = -,
  11.          Success = -,
  12.          Info = -,
  13.          Warning = -,
  14.          Error = -
  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 = ;
  15.  
  16.          public int CloseTime
  17.          {
  18.              get { return m_CloseTime; }
  19.              set
  20.              {
  21.                  m_CloseTime = value;
  22.                  if (value > )
  23.                      timer1.Interval = value;
  24.              }
  25.          }

提供一些公共函数

  7.          /// </summary>
  8.          public static void ClearTips()
  9.          {
  10.              for (int i = m_lstTips.Count - ; i >= ; 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

  26.          public void ResetTimer()
  27.          {

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");
