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

 1    #region 显示一个模式信息框

48             return result;

50         #endregion

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             }
