整理下在公司的时候一些小技巧性代码

　　    转眼间已经离开公司小半年了，这期间创业真实辛苦不少，天天起早贪黑的，真是累人，网店终于有了点小起色，能够养活自己了，但是如何做大，怎么做好，还有资金的问题，又是摆在面前的难关啊。。。

　　    自己为了方便，偶尔写一些小软件，每次写的时候都发现手生了好多，很多东西以前用到过，但是就是想不起来，所以在这里做个整理吧，方便以后使用：

1 。全角半角转换

        /// <summary>
        /// 转全角的函数(SBC case)
        /// </summary>
        /// <param name="input">任意字符串</param>
        /// <returns>全角字符串</returns>
        ///<remarks>
        ///全角空格为12288，半角空格为32
        ///其他字符半角(33-126)与全角(65281-65374)的对应关系是：均相差65248
        ///</remarks>
        public string ToSBC(string input)
        {
            //半角转全角：
            char[] c = input.ToCharArray();
            for (int i = 0; i < c.Length; i++)
            {
                if (c[i] == 32)
                {
                    c[i] = (char)12288;
                    continue;
                }
                if (c[i] < 127)
                    c[i] = (char)(c[i] + 65248);
            }
            return new string(c);
        }


        /// <summary> 转半角的函数(DBC case) </summary>
        /// <param name="input">任意字符串</param>
        /// <returns>半角字符串</returns>
        ///<remarks>
        ///全角空格为12288，半角空格为32
        ///其他字符半角(33-126)与全角(65281-65374)的对应关系是：均相差65248
        ///</remarks>
        private string ToDBC(string input)
        {
            char[] c = input.ToCharArray();
            for (int i = 0; i < c.Length; i++)
            {
                if (c[i] == 12288)
                {
                    c[i] = (char)32;
                    continue;
                }
                if (c[i] > 65280 && c[i] < 65375)
                    c[i] = (char)(c[i] - 65248);
            }
            return new string(c);
        }

 

2。 过滤危险字符，防止SQL注入

        /// <summary>
        /// 过滤危险字符（防止Sql注入）
        /// </summary>
        /// <param name="contents">预检测的内容</param>
        /// <returns>返回True或false</returns>
        private bool HasDangerousContents(string contents)
        {
            bool bReturnValue = false;
            if (contents.Length > 0)
            {
                //convert to lower
                string sLowerStr = contents.ToLower();
                //RegularExpressions
                string sRxStr = @"(\sand\s)|(\sand\s)|(\slike\s)|(select\s)|(insert\s)|(delete\s)|(update\s[\s\S].*\sset)|(create\s)|(\stable)|(<[iframe|/iframe|script|/script])|(')|(\sexec)|(\sdeclare)|(\struncate)|(\smaster)|(\sbackup)|(\smid)|(\scount)";
                //Match
                bool bIsMatch = false;
                System.Text.RegularExpressions.Regex sRx = new System.Text.RegularExpressions.Regex(sRxStr);
                bIsMatch = sRx.IsMatch(sLowerStr, 0);
                if (bIsMatch)
                {
                    bReturnValue = true;
                }
            }
            return bReturnValue;
        }

 

3。 防止死锁，让处理器处理其他，可以不用线程防止UI死锁，但是影响运行速度

        public void VBSleep(int time)
        {

            for (int i = 0; i < time; i++)
            {
                Application.DoEvents();
            }

        }

 

 

4。Request请求

        /// <summary>
        /// 进行Request连接发送
        /// </summary>
        /// <param name="postData"></param>
        /// <returns></returns>
        private string doRequest(string url,string postData)
        {
            byte[] byteArray = Encoding.UTF8.GetBytes(postData); // 转化
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url));
            request.ContentType = "application/x-www-form-urlencoded";
            request.Accept = "text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
            request.Referer = "http://www.tfsshop.com/?";
            request.ContentLength = byteArray.Length;
            request.Method = "POST";
            request.Timeout = 12000;
            request.CookieContainer = CookieContainer;
            //是否需要代理
           // if (false)
           // {
           // //    WebProxy wp = new WebProxy(Tools.Config.ProxyAdress, Tools.Config.ProxyPoint);
           //     //代理是否需要身份验证
           ////     if (Tools.Config.UseProxyPassport) wp.Credentials = new System.Net.NetworkCredential(Tools.Config.ProxyPassportName,
           // //                                                                                         Tools.Config.ProxyPassportPassword,
           // //                                                                                         Tools.Config.ProxyPassportDomain);
           //     request.Proxy = wp;
           // }
            string res = "";
            try
            {
                Stream newStream = request.GetRequestStream();
                newStream.Write(byteArray, 0, byteArray.Length);    //写入参数
                newStream.Close();
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                res = sr.ReadToEnd();
                response.Close();
            }
            catch (Exception e)
            {
                res = e.Message;
            }
            return res;
        }

 

5。PictureBox异步加载图片

        void loadGoodImage(string id)
        {
            //图片异步加载完成后的处理事件
            pictureBox1.LoadCompleted += new AsyncCompletedEventHandler(pictureBox1_LoadCompleted);
            //图片加载时，显示等待光标
            pictureBox1.UseWaitCursor = true;
            //采用异步加载方式
            pictureBox1.WaitOnLoad = false;

            //开始异步加载，图片的地址，请自行更换

                //连接服务器获得图片
                pictureBox1.LoadAsync(string.Format("http://imgs.tfsshop.com/shop/l/{0}.jpg", id));

        }

        void pictureBox1_LoadCompleted(object sender, AsyncCompletedEventArgs e)
        {
            //图片加载完成后，将光标恢复
            pictureBox1.UseWaitCursor = false;
        }

        {
            WritePrivateProfileString(type, Key, Value, IniPath + "Setting.ini");
        }
        public static string readSetting(string type, string Key)
        {
            StringBuilder temp = new StringBuilder(255);
            int i = GetPrivateProfileString(type, Key, "", temp, 255, IniPath + "Setting.ini");
            return temp.ToString();
        }
    }

先记这么多，后面想起来了再整理
