17、EventArgs e)this.lstResults.Items.Clear( );例5-10：源代码：private void btnMsgBox_Click(object sender, EventArgs e)MessageBox.Show(“这是第一个消息框，只有确认按钮“); /显示最简单的MessageBoxMessageBox.Show(“这是二个消息框，有标题，只有确认按钮“, “第二个消息框“); /显示有文本和标题的MessageBox/显示具有文本、标题、确定和取消按钮的MessageBoxMessageBox.Show(“这是第三个消息框，有标题，只有确认和取消按钮“

18、, “第三个消息框“, MessageBoxButtons.OKCancel); /显示具有文本、标题、确定和取消按钮、告警图标的MessageBoxMessageBox.Show(“这是第四个消息框，有标题，只有确认和取消按钮，告警图标“, “第四个消息框“, MessageBoxButtons.OKCancel，MessageBoxIcon.Warning);例5-11：源代码：private void btnOpenFile_Click(object sender, EventArgs e)OpenFileDialog ofdlg = new OpenFileDialog( ); /创建

19、OpenFileDialog对象ofdlg.Filter = “文本文件(*.txt)|*.TXT|Word文件(*.doc)|*.DOC“; /只选择TXT和DOC扩展名文件ofdlg.Title = “选择文本文件或Word文件“; /设置对话框的标题if(ofdlg.ShowDialog() = DialogResult.OK) /显示对话框，并等待返回this.tbOpenFileName.Text = ofdlg.FileName; /如果用户选择了文件则显示到界面elsethis.tbOpenFileName.Text = “还没有选择要打开的文件“; /没有选择文件，则显示默认提

20、示例5-12：源代码：private void btnSetColor_Click(object sender, EventArgs e)ColorDialog cdlg = new ColorDialog( ); /创建ColorDialog对象cdlg.Color = btnSetColor.ForeColor; /设置默认颜色为btnSetColor当前前景色if (cdlg.ShowDialog( ) = DialogResult.OK) /显示对话框，并等待返回this.btnSetColor.ForeColor = cdlg.Color; /选择了新的颜色，则更新btnSetCol

21、or前景色例5-13：源代码：private void btnSetFont_Click(object sender, EventArgs e)FontDialog fdlg = new FontDialog( ); /创建FontDialog对象fdlg.Font = btnSetFont.Font; /设置默认字体为btnSetFont当前字体if (fdlg.ShowDialog( ) = DialogResult.OK) /显示对话框，并等待返回this.btnSetFont.Font = fdlg.Font; /选择了新的字体，则更新btnSetFont的字体四、实验总结通过此次实验，我学会了在 Visual Studio 2010 中创建和运行窗体程序；也掌握了 Windows 窗体的基本操作；学习使用了常用的Windows 控件；同时学会了使用菜单和工具栏以及通用对话框。
