1.窗体页面按键判断  
   （1）单键判断  
      if (e.KeyCode == Keys.Delete)  
       \{  
         //处理逻辑  
       \}   
   （2）组合建判断：    
      if (e.Modifiers.CompareTo(Keys.Control) == 0 && e.KeyCode == Keys.Delete)  
      \{  
       //处理逻辑  
      \}

2.C\#WinForm的密码输入框禁止粘贴和右键  
       private void LoginForm\_Load(object sender, EventArgs e)  
        \{  
            txtPassword.ContextMenu = new ContextMenu();  
            txtPassword.KeyPress += new KeyPressEventHandler(txtPassword\_KeyPress);  
        \}

void txtPassword\_KeyPress(object sender, KeyPressEventArgs e)  
        \{  
            if ((int)e.KeyChar == 22)  
            \{  
                e.Handled = true;  
            \}  
        \}

3.    拷贝文件夹(递归)

//要拷贝的文件路径  
          string dataFileName="";  
        //指定文件路径的目录信息  
          DirectoryInfo source = new DirectoryInfo(Path.GetDirectoryName(dataFileName));  
        //本地文件路径  
         string localFilePath = "C:\\\\temp\\\\";  
        //本地文件目录  
        DirectoryInfo localDirectory = new DirectoryInfo(localFilePath);  
       
         /// <summary>  
        /// 拷贝文件夹()  
        /// </summary>  
        /// <param name="source">要拷贝指定文件目录信息</param>  
        /// <param name="destination">本地文件目录信息</param>  
        private void CopyDirectory(DirectoryInfo source, DirectoryInfo destination)  
        \{              
            if (!destination.Exists) \{  
                destination.Create();  
            \}  
            FileInfo\[\] files = source.GetFiles();  
            foreach (FileInfo file in files)  
            \{  
                file.CopyTo(Path.Combine(destination.FullName, file.Name));  
            \}  
            DirectoryInfo\[\] dirs = source.GetDirectories();  
            foreach (DirectoryInfo dir in dirs)  
            \{                             
                string destinationDir = Path.Combine(destination.FullName, dir.Name);                           
                CopyDirectory(dir, new DirectoryInfo(destinationDir));  
            \}  
        \}

4. 获取资源文件（Xml）--要在同一命名空间下获取  
     XmlDocument myXml = new XmlDocument();             
     string fileName = "AdminClient.Resources.bpmsCodes.xml";  
     Assembly asm = Assembly.GetExecutingAssembly();//读取嵌入式资源  
     Stream strm = asm.GetManifestResourceStream(fileName);  
     myXml.Load(strm);//读取指定的XML文档

5.设置窗体的初始位置  
      this.StartPosition = FormStartPosition.Manual; //必须先设置这个属性  
      this.Location = = new Point(this.pointX, this.pointY + this.InputControl.Height + 30);
