问题描述

我想使用字符文字和数字自动生成代码（SH / OPD / 2015/01），应该是自动增量，PLZ帮助我。我的代码是

  string  NewCode =  ; 
  string  str =  ; 
 str =  选择Opdid From temp; 
 str =  从opd_reg中选择MAX（Opdid）AS'Oddid'; 
 DataSet ds =  new  DataSet（）; 
 ds = c.ExecuteSQL（str）; 
  if （ds.Tables [ 0 ]。Rows.Count >   0 ）
 {
  string  maxMainCode = ds.Tables [ 0 ]。行[ 0 ] [  Opdid]。ToString（）; 
  //   int NewCount = Convert.ToInt32（Code.Substring（2））+ 1;  
  if （maxMainCode！=   ）
 {
  string  [] arInfo =  new   string  [ 150 ]; 
  char  [] splitter1 = {'  S '}; 
  char  [] splitter2 = {'  H '}; 
  char  [] splitter3 = {'  / '}; 
 
  char  [] splitter4 = {'  O'}; 
  char  [] splitter5 = {'  P '}; 
  char  [] splitter6 = {'  D '}; 
  char  [] splitter7 = {'  / '}; 
  char  [] splitter8 = {'  2 '}; 
  char  [] splitter9 = {'  0 '}; 
  char  [] splitter10 = {'  1 '}; 
  char  [] splitter11 = {'  5 '}; 
  char  [] splitter12 = {'  / '}; 
 
 arInfo = maxMainCode.Split（splitter1）; 
 arInfo = maxMainCode.Split（splitter2）; 
 arInfo = maxMainCode.Split（splitter3）; 
 arInfo = maxMainCode.Split（splitter4）; 
 arInfo = maxMainCode.Split（splitter5）; 
 arInfo = maxMainCode.Split（splitter6）; 
 arInfo = maxMainCode.Split（splitter7）; 
 arInfo = maxMainCode.Split（splitter8）; 
 arInfo = maxMainCode.Split（splitter9）; 
 arInfo = maxMainCode.Split（splitter10）; 
 arInfo = maxMainCode.Split（splitter11）; 
 arInfo = maxMainCode.Split（splitter12）; 
 
  int  OrignalNum = Convert.ToInt32（arInfo [ 180 ]。ToString（ ））; 
  int 添加; 
 Add = OrignalNum +  10 ; 
  if （Convert.ToString（OrignalNum）.Length == Convert.ToString（Add）.Length）
 {
 NewCode = maxMainCode.Replace（OrignalNum.ToString（），Add.ToString（））; 
} 
  else  
 {
 NewCode = maxMainCode.Replace（   0 + OrignalNum.ToString（），Add.ToString（））; 
} 
} 
  else  
 {
 NewCode =    SH / OPD / 2015/01; 
 
} 
} 
  else  
 {
 NewCode =   SH / OPD / 2015/01; 
 objs.Stmt =  插入临时（Opdid）值（' + NewCode +  '）; 
 objs.CallQuery（objs）; 
} 
 返回 NewCode; 
}

解决方案

i want to auto generate code using character literals and digit like this (SH/OPD/2015/01),Is should be auto increment,plz help me.My code is

string NewCode = "";
           string str = "";
           str = "Select Opdid From temp";
           str = "Select MAX(Opdid) AS 'Opdid' from opd_reg";
           DataSet ds = new DataSet();
           ds = c.ExecuteSQL(str);
           if (ds.Tables[0].Rows.Count > 0)
           {
               string maxMainCode = ds.Tables[0].Rows[0]["Opdid"].ToString();
               // int NewCount = Convert.ToInt32(Code.Substring(2))+1;
               if (maxMainCode != "")
               {
                   string[] arInfo = new string[150];
                   char[] splitter1 = { 'S' };
                   char[] splitter2 = { 'H' };
                   char[] splitter3 = { '/' };

                   char[] splitter4 = { 'O' };

                   arInfo = maxMainCode.Split(splitter12);

                   int OrignalNum = Convert.ToInt32(arInfo[180].ToString());
                   int Add;
                   Add = OrignalNum + 10;
                   if (Convert.ToString(OrignalNum).Length == Convert.ToString(Add).Length)
                   {
                       NewCode = maxMainCode.Replace(OrignalNum.ToString(), Add.ToString());
