准备工作
这是一个提示消息的窗体，他继承自基类窗体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
提示消息窗体支持有确定取消按钮及单取消按钮，更多操作按钮暂没有增加
开始
添加一个Form命名为FrmDialog ，继承FrmBase
私有的构造函数
1 private FrmDialog( 2 string strMessage, 3 string strTitle, 4 bool blnShowCancel = false, 5 bool blnShowClose = false, 6 bool blnisEnterClose = true) 7 { 8 InitializeComponent(); 9 if (!string.IsNullOrWhiteSpace(strTitle)) 10 lblTitle.Text = strTitle; 11 lblMsg.Text = strMessage; 12 if (blnShowCancel) 13 { 14 this.tableLayoutPanel1.ColumnStyles[1].Width = 1; 15 this.tableLayoutPanel1.ColumnStyles[2].Width = 50; 16 } 17 else 18 { 19 this.tableLayoutPanel1.ColumnStyles[1].Width = 0; 20 this.tableLayoutPanel1.ColumnStyles[2].Width = 0; 21 } 22 btnClose.Visible = blnShowClose; 23 blnEnterClose = blnisEnterClose; 24 }
搭配一个静态的公共函数

FormStartPosition.CenterParent : FormStartPosition.CenterScreen, 44 IsShowMaskDialog = isShowMaskDialog, 45 TopMost = true 46 }.ShowDialog(owner); 47 } 48 return result; 49 } 50 #endregion
一些小事件

用处及效果
用处：一般用在一个需要用户确定的提示上
效果：
调用示例
1 if (FrmDialog.ShowDialog(this, "是否再显示一个没有取消按钮的提示框？", "模式窗体测试", true) == System.Windows.Forms.DialogResult.OK) 2 { 3 FrmDialog.ShowDialog(this, "这是一个没有取消按钮的提示框", "模式窗体测试"); 4 }
