简介：

正文

1. IntPtr转换成byte[]

         public byte [] ConvertToBytes(IntPtr dataBuf, int length)
        {
             byte [] byteBuf = new byte [length];
            Marshal.Copy(dataBuf, byteBuf, 0 , length);
             return byteBuf;
        }

2. 读写INI文件

一般用于读写配置文件

     /// <summary>
     /// 读写INI文件
     /// </summary>
     public class IniFile
    {
         /// <summary>
         /// 文件INI名称
         /// </summary>
         public string Path;

         /// <summary>
         /// 声明读写INI文件的API函数
         /// </summary>
         /// <param name="section"></param>
         /// <param name="key"></param>
         /// <param name="val"></param>
         /// <param name="filePath"></param>
         /// <returns></returns>
        [DllImport( " kernel32 " )]
         private static extern long WritePrivateProfileString( string section, string key, string val, string filePath);

        [DllImport( " kernel32 " )]
         private static extern int GetPrivateProfileString( string section, string key, string def, StringBuilder retVal, int size, string filePath);

         /// <summary>
         /// 类的构造函数，传递INI文件名
         /// </summary>
         /// <param name="inipath"></param>
         public IniFile( string inipath)
        {
             //
             // TODO: Add constructor logic here
             //
            Path = inipath;
        }

         /// <summary>
         /// 写INI文件
         /// </summary>
         /// <param name="Section"></param>
         /// <param name="Key"></param>
         /// <param name="Value"></param>
         public void IniWriteValue( string Section, string Key, string Value)
        {
            WritePrivateProfileString(Section, Key, Value, this .Path);

        }

         /// <summary>
         /// 读取INI文件指定
         /// </summary>
         /// <param name="Section"></param>
         /// <param name="Key"></param>
         /// <returns></returns>
         public string IniReadValue( string Section, string Key)
        {
            StringBuilder temp = new StringBuilder( 5000 );
             int i = GetPrivateProfileString(Section, Key, "" , temp, 5000 , this .Path);
             return temp.ToString();

        }
    }

3. 获取网卡号

可用于软件加密

         /// <summary>
         /// 获得网卡号
         /// </summary>
         /// <returns></returns>
         public static string GetNetCardMacAddress()
        {
            ManagementClass mc = new ManagementClass( " Win32_NetworkAdapterConfiguration " );
            ManagementObjectCollection moc = mc.GetInstances();
             string str = "" ;
             foreach (ManagementObject mo in moc)
            {
                 if (( bool )mo[ " IPEnabled " ] == true )
                    str = mo[ " MacAddress " ].ToString();
            }
             return str;
        }

4. 获取采集卡序列化

可用于软件加密绑定，注意结构体DS_BOARD_DETAIL.sn是16位的，但是实际只有12位，VC++源码也只取了12位，后门都是0。

         /// <summary>
         /// 获取板卡序号
         /// </summary>
         /// <returns></returns>
         public static string GetBoardSN()
        {
             uint boardCount = HikVisionSDK.GetBoardCount();
            StringBuilder sn = new StringBuilder();
             for ( uint i = 0 ; i < boardCount; )
            {
                DS_BOARD_DETAIL boardDetail = new DS_BOARD_DETAIL();
                HikVisionSDK.GetBoardDetail(i, ref boardDetail);
                 for ( int j = 0 ; j < 12 ; j ++ )
                {
                    sn.Append(( char )(boardDetail.sn[j] + 0x30 ));
                }
                 break ;
            }
             return sn.ToString();
        }

5. 全屏显示视频窗口

        /// <summary>
         /// 全屏
         /// </summary>
         /// <param name="tsmFullScreen"> 右键 </param>
         /// <param name="pVideo"> 显示视频的窗口 </param>
         /// <param name="cs"> 视频连接成功返回的值 </param>
         private void FullScreen(ToolStripMenuItem tsmFullScreen, Panel pVideo, int cs)
        {
             if ( this .WindowState == System.Windows.Forms.FormWindowState.Maximized)
            {
                tsmFullScreen.Text = " 全屏窗口 " ;
                 this .FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
                 this .WindowState = System.Windows.Forms.FormWindowState.Normal;
                 this .TopMost = false ;
                pVideo.Width = pre_Width;
                pVideo.Height = pre_Height;
                pVideo.Top = pre_Top;
                pVideo.Left = pre_Left;

                 // 隐藏其他控件
                HideOtherControls(pVideo, true );

                minPanel(pVideo, cs);
            }
             else
            {
                tsmFullScreen.Text = " 关闭全屏 " ;
                 this .FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
                 this .WindowState = System.Windows.Forms.FormWindowState.Maximized;
                 this .TopMost = true ;

                pre_Width = pVideo.Width;
                pre_Height = pVideo.Height;
                pre_Top = pVideo.Top;
                pre_Left = pVideo.Left;

                pVideo.Width = this .Width;
                pVideo.Height = this .Height;
                pVideo.Top = 0 ;
                pVideo.Left = 0 ;

                 // 显示其他控件
                HideOtherControls(pVideo, false );
            }
        }

6. 其他代码

         // 判断是不是IP地址
         public bool IsIPAddress( string ip)
        {
             return Regex.IsMatch(ip, @" ^((2[0-4]\d|25[0-5]|[01]?\d\d?)\.){3}(2[0-4]\d|25[0-5]|[01]?\d\d?)$ " );
        }
         /// <summary>
         /// 是否是无符号整数(正数)
         /// </summary>
         /// <param name="value"></param>
         /// <returns></returns>
         public bool IsUInt( string value)
        {
             return Regex.IsMatch(value, @" ^\d*$ " );
        }

结束

实际开发中远不只这么多，基本上也是有一个这样的功能需求就去GOOGLE一段代码出来，还有其他如delegate和event在窗体之间使用，分屏也是简单的采用了4个Panel，当放大时就分别隐藏其他Panel等等，就不一一列举了，多查查资料就行了: )
