10、c partial class FrmMain : Form private int childFormNumber = 0; public FrmMain( ) InitializeComponent( ); private void ShowNewForm(object sender, EventArgs e) Form childForm = new Form( ); childForm.MdiParent = this; childForm.Text = 窗口 + childFormNumber+; childForm.Show( ); private void OpenFile(ob

11、ject sender, EventArgs e) OpenFileDialog ofdlg = new OpenFileDialog( ); /创建OpenFileDialog对象ofdlg /设置打开文件对话框的默认路径为“我的文档” ofdlg.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Personal); ofdlg.Filter = 文本文件(*.txt)|*.txt; /设置只接受txt为扩展名的文件 if (ofdlg.ShowDialog(this) = DialogResult

12、.OK) /显示打开文件对话框 string fileName = ofdlg.FileName; /获取要打开的文件名 FrmReader frm = new FrmReader(fileName); /创建查看文件的子窗体frm frm.MdiParent = this; /设置子窗体frm的父窗体为当前窗体 frm.Show( ); /显示子窗体 private void SaveAsToolStripMenuItem_Click(object sender, EventArgs e) SaveFileDialog saveFileDialog = new SaveFileDialog(

19、ngDlg dlg = new SettingDlg(this._ViewBackColor, /用当前阅读参数创建SettingDlg对象dlg this._ViewForeColor, this._ViewFont); if (dlg.ShowDialog(this) = DialogResult.OK) /显示参数设置对话框，并等待用户设置 this._ViewBackColor = dlg.GetBackColor( ); /获取用户最新的阅读参数 this._ViewFont = dlg.GetFont( ); this._ViewForeColor = dlg.GetForeCol

20、or( ); foreach (Form frm in this.MdiChildren) /遍历所有子窗体 FrmReader frmRd = frm as FrmReader; /如果子窗体是FrmReader类型 if (frmRd != null) /则更新最新参数到子窗体 frmRd.SetViewSettings(this._ViewBackColor, this._ViewForeColor, this._ViewFont); （2）源代码：namespace MultiTextReader partial class AboutBox : Form public AboutBo

21、x( ) InitializeComponent( ); this.Text = String.Format(关于 0 0, AssemblyTitle); this.labelProductName.Text = AssemblyProduct; this.labelVersion.Text = String.Format(版本 0 0, AssemblyVersion); this.labelCopyright.Text = AssemblyCopyright; this.labelCompanyName.Text = AssemblyCompany; this.textBoxDescription.Text = AssemblyDescription; 四、实验总结通过此次实验，我学会了在Visual Studio 2010中创建多文档应用程序；也基本掌握了在多文档窗体添加子窗体到父窗体的具体方法；对于操作、排列子窗体进行了相应的练习。实验比较顺利，并没有出现什么技术问题。
