處理數(shù)據(jù)批量生成sql插入語(yǔ)句

最近在做一個(gè)天氣預(yù)報(bào)模塊，首先需要將客戶端公網(wǎng)ip轉(zhuǎn)換成所在城市，然后將所在城市名轉(zhuǎn)換成對(duì)應(yīng)的城市代碼，在網(wǎng)上找到了城市代碼，但是需要處理一下，看了看，有三百多城市及對(duì)應(yīng)的城市代碼，想存到數(shù)據(jù)庫(kù)。就想著做一個(gè)數(shù)據(jù)處理自動(dòng)生成sql語(yǔ)句的工具，提高效率。

城市代碼

一看上去很亂的，而且對(duì)應(yīng)關(guān)系是每個(gè)省城市一行，代碼一行，分別用引號(hào)引起，用逗號(hào)分隔，每行間都沒有符號(hào)分隔，省名沒有用引號(hào)。首先是想著把省名去掉，因?yàn)槊總€(gè)城市名都是不相同的。想著每?jī)尚袃尚械娜ヌ幚?，但是也要費(fèi)不少功夫，還容易出錯(cuò)。就想個(gè)索性一次性的全處理的算法。

   ps：界面很簡(jiǎn)單，上面是輸入數(shù)據(jù)，中間是轉(zhuǎn)換，下面是輸出數(shù)據(jù)。

后臺(tái)主要代碼：
[csharp] view plain copy

    private void button1_Click(object sender, EventArgs e)  
    {  
        string data = textBox1.Text.Replace("\r", "").Replace("\n", "").Replace("\t", "").Replace(" ", "").Replace(" ", "").Replace("    ", "");  
        MatchCollection matchsdata = matches(data, "\"[\\s\\S]*?\"");  
        string[,] temps = new string[matchsdata.Count / 2, 2];  
        int count0 = 0;  
        int count1 = 0;  
        string input = string.Empty;  
        foreach (Match m in matchsdata)  
        {  
            string tempdata = m.Value.Replace("\"", "");  
            try  
            {  
                int tryp = int.Parse(tempdata);  
                temps[count1, 1] = tempdata;  
                count1++;  
            }  
            catch (Exception ex)  
            {  
                temps[count0, 0] = tempdata;  
                count0++;  
            }  
        }  
        for (int i = 0; i < (matchsdata.Count / 2); i++)  
        {  
            input += "insert into tbl_CityCode(c_city,c_code) values('" + temps[i, 0] + "','" + temps[i, 1] + "')\r\n";  
        }  
        textBox2.Text = input;  
    }  
      
    public static MatchCollection matches(string str, string exp)  
    {  
        return Regex.Matches(str, exp, RegexOptions.IgnoreCase);  
    }  

 首先是將輸入的數(shù)據(jù)處理，去除換行符，空格什么的。然后你應(yīng)該是會(huì)得到一行數(shù)據(jù)，然后通過正則表達(dá)式匹配出所有帶引號(hào)的數(shù)據(jù)，你會(huì)發(fā)現(xiàn)需要的數(shù)據(jù)全部都是用引號(hào)引起來的，但是怎樣區(qū)分城市名和城市代碼呢，它們是混在一起的。不用擔(dān)心，你發(fā)現(xiàn)了嗎？城市名是字符串，城市代碼是一串?dāng)?shù)字，我們只要將匹配出的數(shù)據(jù)數(shù)組遍歷，每一行數(shù)據(jù)都去轉(zhuǎn)換成int類型，這樣城市名的行就會(huì)報(bào)錯(cuò)，在catch中捕捉，這一行就是城市名，沒錯(cuò)的就是城市代碼，把數(shù)據(jù)一次存到一個(gè)二維數(shù)組，對(duì)應(yīng)的列中就行了。這樣就會(huì)獲得了相對(duì)應(yīng)的城市名和城市代碼。生成的sql語(yǔ)句要對(duì)應(yīng)相應(yīng)的數(shù)據(jù)庫(kù)表。
表結(jié)構(gòu)：
轉(zhuǎn)換完了將生成的sql語(yǔ)句放到查詢器中執(zhí)行就ok了。共處理了349個(gè)城市。
最后不放心自己的算法，隨機(jī)抽查了幾條數(shù)據(jù)，沒有錯(cuò)誤。
