inserting into SQL via sqlbulk - sqlbulkcopy

Question

hallo i have this sniped code like this:
public static void Put_CSVtoSQL_Adhesion()
{
bool IsFirst = true;
DataTable dt = new DataTable();
string line = null;
int i = 0;
try
{
string fileName = Path.Combine(HttpContext.Current.Server.MapPath(UploadDirectory), TheFileName);
using (StreamReader sr = File.OpenText(fileName))
{
while ((line = sr.ReadLine()) != null)
{
string[] data = line.Split(';');
if (data.Length > 0)
{
if (i == 0)
{
foreach (var item in data)
{
dt.Columns.Add(new DataColumn());
}
i++;
}
DataRow row = dt.NewRow();
row.ItemArray = data;
// Pour enlever la tete
if (!IsFirst) dt.Rows.Add(row);
IsFirst = false;
}
}
}
using (var connectionWrapper = new Connexion())
{
var connectedConnection = connectionWrapper.GetConnected();
using (SqlBulkCopy copy = new SqlBulkCopy(connectionWrapper.conn))
{
int CountColl = dt.Columns.Count;
copy.ColumnMappings.Add(0, 1);
copy.ColumnMappings.Add(1, 2);
copy.ColumnMappings.Add(2, 3);
copy.ColumnMappings.Add(3, 4);
copy.ColumnMappings.Add(4, 5);
copy.DestinationTableName = "cotisation";
copy.WriteToServer(dt);
}
}
}
catch (Exception excThrown)
{
throw new Exception(excThrown.Message);
}
}
this code work well, but now i have more than 60 column, should i type manualy from 1 to 60 column or there are another methode ?
copy.ColumnMappings.Add(0, 1);
copy.ColumnMappings.Add(1, 2);
copy.ColumnMappings.Add(2, 3);
copy.ColumnMappings.Add(3, 4);
copy.ColumnMappings.Add(4, 5);
...until 60 column ?
the column is all the same i just shifted 1 column, because the first one is autoincremented column as an ID

Answer 1

Write a loop?
for (int i = 0; i < dt.Columns.Count - 1; i++)
{
copy.ColumnMappings.Add(i, i + 1);
}
