把CSV文件读到一个DataTable中

在处理CSV文件的时候发现，不能简单的用逗号来拆分内容，如果在双引号里面有逗号，那么这行将解析错误。最后找到个用正则表达式来splite的简单方面。原理就是用","来作为拆分的标记。   

/// <summary>
        /// 把一个CSV文件读到一个DataTable中
        /// </summary>
        /// <param name="strpath">文件完整路径</param>
        /// <returns>DataTable</returns>
        public static DataTable GetTable(string strpath)
        {
            Regex reg = new Regex("\",\"");
            int intColCount = 0;
            DataTable mydt = new DataTable("myTableName");

            //DataColumn mydc;
            //DataRow mydr;

            //string strpath = "";
            string strline;
            string[] aryline;

            StreamReader mysr = new StreamReader(strpath,System.Text.Encoding.Default);
            strline = mysr.ReadLine();

            aryline = reg.Split(strline);

            intColCount = aryline.Length;
            for (int i = 0; i < aryline.Length; i++)
            {
                DataColumn mydc = new DataColumn(aryline[i].Replace("\"", ""), typeof(string));
                mydt.Columns.Add(mydc);
            }
           
            while ((strline = mysr.ReadLine()) != null)
            {
                aryline = reg.Split(strline);
               
                DataRow mydr = mydt.NewRow();
                for (int i = 0; i < intColCount; i++)
                {
                    mydr[i] = aryline[i].Replace("\"","");
                }
                mydt.Rows.Add(mydr);
            }
            return mydt;
        }
