will the length of data that you want to extract remain same?

Solution 1

use the

String.substring

to split the string and save it into your database using Insert command.

i have to split this whole code (31201011281853000100000000710003) into 5 parts, is it possible to do that by using substring?

string sql = "",code = "",Inout = "",EmployeeCode = "",TerminalNo = "";
int year = 0,month = 0,day = 0,hour = 0,minute = 0;

string text = string.Empty;
UploadId = Convert.ToInt32(munshi.getcolnum("select MAX(isnull(uploadid,0)) + 1              from attendance"));
                            if (UploadId == -1)
                            {
                                UploadId = UploadId + 1;
                            }
                            do
                            {
                                text = reader.ReadLine();
                                if (text == null)
                                    break;
                                else if (text == string.Empty)
                                {
                                    text = "1";
                                    continue;
                                }

                                #region         S p l i t t i n g         D a t e
                                year = Convert.ToInt32(text.Substring(2, 4));
                                month = Convert.ToInt32(text.Substring(6, 2));
                                day = Convert.ToInt32(text.Substring(8, 2));
                                hour = Convert.ToInt32(text.Substring(10, 2));
                                minute = Convert.ToInt32(text.Substring(12, 2));
                                #endregion

                                code = text.Substring(0, 2);
                                Inout = text.Substring(14, 4);
                                EmployeeCode = text.Substring(18, 10);
                                TerminalNo = text.Substring(28, 4);
                                DateTime date = new DateTime(year,month,day,hour, minute, 0);

                            }
                            while (!string.IsNullOrEmpty(text));
