I am using the ASP.NET MVC. here is the code that might help you that how to you convert the CSV file in List and after that you will able to save the List data in to SQL.
[HttpPost]
public ActionResult Create(t_NextDevAttendence t_nextdevattendence, IEnumerable<HttpPostedFileBase> files)
{
// Read the CSV file name & file path
// I am usisg here Kendo UI Uploader
string path = "";
string filenamee = "";
if (files != null)
{
foreach (var file in files)
{
var fileName = Path.GetFileName(file.FileName);
path = Path.GetFullPath(file.FileName);
filenamee = fileName;
}
// Read the CSV file data
StreamReader sr = new StreamReader(path);
string line = sr.ReadLine();
string[] value = line.Split(',');
DataTable dt = new DataTable();
DataRow row;
foreach (string dc in value)
{
dt.Columns.Add(new DataColumn(dc));
}
while (!sr.EndOfStream)
{
value = sr.ReadLine().Split(',');
if (value.Length == dt.Columns.Count)
{
row = dt.NewRow();
row.ItemArray = value;
dt.Rows.Add(row);
}
}
// Insert CSV data in List
List<EmpAttendence> employeeList = new List<EmpAttendence>();
var myEnumerable = dt.AsEnumerable();
foreach (var item in myEnumerable)
{
// set the CSV file column with my class
// here it is Important that all field should be string when your inset in DB
EmpAttendence emp = new EmpAttendence();
emp.EmployeeId = item.Field<String>("User ID");
emp.EntryDate = item.Field<String>("Date");
emp.EntryTime = item.Field<String>("Time");
emp.fileName = filenamee;
employeeList.Add(emp);
}
// Insert in database from List
foreach (var item in employeeList)
{
// table name
t_NextDevAttendence t_next = new t_NextDevAttendence();
t_next.EmployeeCode = item.EmployeeId;
t_next.EntryDate = item.EntryDate;
t_next.EntryTime = item.EntryTime;
t_next.CSVFileName = item.fileName;
db.t_NextDevAttendence.AddObject(t_next);
}
db.SaveChanges();
return RedirectToAction("Index");
}
return View(t_nextdevattendence);
}
