C#小程序—帶歷史的菜單

 前幾天寫了個帶歷史菜單功能的程序，寫的不是很好，太過於復雜。昨天我發現一種新方法，於是從寫一遍。動態添加菜單的代碼如下：
[csharp] 
//Menu.ini 是配置文件，來存儲歷史。 
if (File.Exists("Menu.ini")) 
{ 
    StreamReader sr = new StreamReader("Menu.ini"); 
    int i = this.文件ToolStripMenuItem.DropDownItems.Count - 2; 
    while (sr.Peek() > 0) 
    { 
        ToolStripMenuItem tlomenu = new ToolStripMenuItem(sr.ReadLine()); 
        this.文件ToolStripMenuItem.DropDownItems.Insert(i, tlomenu); 
        i++; 
    } 
    sr.Close(); 
} 

              我還把程序的流程用Visio簡單的畫了一下。

        
         下面是幫助窗口的代碼：
        
[csharp] 
/調用API函數 
        [DllImport("user32")] 
        private static extern long FlashWindow(IntPtr handle, bool bInvert); 
 
        private void btnClose_Click(object sender, EventArgs e) 
        { 
            this.Close(); 
        } 
 
        private void timer1_Tick(object sender, EventArgs e) 
        { 
            FlashWindow(this.Handle, true); 
        } 
        
          選擇字體窗口代碼:
   
[csharp]
public FrmFont(Frm frm) 
        { 
            InitializeComponent(); 
            mianFrm = frm; 
        } 
 
        Frm mianFrm = new Frm(); 
        //定義中間變量. 
        public Font newFont; 
        public bool getBlod; 
        public bool getItalic; 
 
         
        //向程序中添加字體和大小. 
        private void FrmFont_Load(object sender, EventArgs e) 
        { 
            InstalledFontCollection iof = new InstalledFontCollection(); 
            foreach (FontFamily font in iof.Families) 
            { 
                cboFont.Items.Add(font.Name); 
            } 
            for (int i = 1; i < 100; i++) 
                cboSize.Items.Add(i); 
        } 
 
        public void UpdateFrmMain() 
        { 
            if (cboFont.SelectedIndex > 0) 
            { 
                try 
                { 
                    newFont = new Font(cboFont.SelectedItem.ToString(), newFont.Size); 
                } 
                catch 
                { } 
            } 
            if (cboSize.SelectedIndex > 0) 
            { 
                newFont = new Font(newFont.FontFamily, float.Parse(cboSize.SelectedItem.ToString())); 
            } 
            mianFrm.rtbNotePad.Font = newFont; 
        } 
        //字體選擇變化 
        private void cboFont_SelectedIndexChanged(object sender, EventArgs e) 
        { 
            UpdateFrmMain(); 
        } 
        //字體大小下拉欄變化 
        private void cboSize_SelectedIndexChanged(object sender, EventArgs e) 
        { 
            UpdateFrmMain(); 
        } 
 
           程序運行的圖片如下：

         
  主窗體代碼如下：
[csharp] 
//定義變量 
        StreamWriter str=null; 
        string strTemp; 
        string path = System.IO.Directory.GetCurrentDirectory(); 
 
        private void 幫助ToolStripMenuItem_Click(object sender, EventArgs e) 
        { 
            //調用幫助窗體 
            FrmHelp help = new FrmHelp(); 
            help.ShowDialog(); 
        } 
         
        //打開文件 
        private void 打開ToolStripMenuItem_Click(object sender, EventArgs e) 
        { 
            OpenFileDialog ofd = new OpenFileDialog(); 
            if (ofd.ShowDialog() == DialogResult.OK) 
            { 
                this.rtbNotePad.Text+=ofd.FileName; 
                this.rtbNotePad.LoadFile(ofd.FileName,RichTextBoxStreamType.PlainText); 
                string ShortFileName = ofd.FileName.Substring(ofd.FileName.LastIndexOf("\\") + 1); 
                this.Text = ShortFileName; 
 
                ToolStripMenuItem tlomenu = new ToolStripMenuItem(ofd.FileName); 
                int i = this.文件ToolStripMenuItem.DropDownItems.Count - 2; 
                this.文件ToolStripMenuItem.DropDownItems.Insert(i, tlomenu); 
                tlomenu.Click += new EventHandler(ToolStripMenuItem_Click); 
            } 
        } 
 
        private void 新建ToolStripMenuItem_Click(object sender, EventArgs e) 
        { 
            SaveFileDialog ofd = new SaveFileDialog (); 
            if(ofd.ShowDialog()==DialogResult.OK) 
            {

            } 
        }
