J'ai créé un datatable et essayer d'insérer ce datatable par SqlBulkCopy mais en quelque sorte, il ne semble pas fonctionner pour moi ....SqlBulkCopy ne semble pas fonctionner pour moi
Je suis l'erreur,
The given value of type DateTime from the data source cannot be converted
to type decimal of the specified target column.
mon DataSource est,
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("EmpId", typeof(Int64)));
dt.Columns.Add(new DataColumn("FromDate", typeof(DateTime)));
dt.Columns.Add(new DataColumn("ToDate", typeof(DateTime)));
dt.Columns.Add(new DataColumn("DaysPresent", typeof(decimal)));
dt.Columns.Add(new DataColumn("OpeningAdvance", typeof(double)));
dt.Columns.Add(new DataColumn("AdvanceDeducted", typeof(double)));
dt.Columns.Add(new DataColumn("RemainingAdvance", typeof(double)));
dt.Columns.Add(new DataColumn("SalaryGiven", typeof(double)));
dt.Columns.Add(new DataColumn("CreatedDate", typeof(DateTime)));
foreach (GridViewRow row in gridEmployee.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
DataRow dr = dt.NewRow();
dr["EmpId"] = Convert.ToInt64(((HiddenField)row.Cells[0].FindControl("HiddenId")).Value);
dr["FromDate"] = Convert.ToDateTime(GetMonthNumberFromAbbreviation(fromdate[1].ToString()) + '/' + fromdate[0].ToString() + '/' + fromdate[2].ToString());
dr["ToDate"] = Convert.ToDateTime(GetMonthNumberFromAbbreviation(todate[1].ToString()) + '/' + todate[0].ToString() + '/' + todate[2].ToString());
dr["DaysPresent"] = Convert.ToDecimal(((TextBox)row.Cells[3].FindControl("TxtDaysPresent")).Text);
dr["OpeningAdvance"] = Convert.ToDouble(((TextBox)row.Cells[4].FindControl("txtOpeningAdv")).Text);
dr["AdvanceDeducted"] = Convert.ToDouble(((TextBox)row.Cells[5].FindControl("TxtAdvanceDeducted")).Text);
dr["RemainingAdvance"] = Convert.ToDouble(((TextBox)row.Cells[6].FindControl("TxtClosingAdvance")).Text);
dr["SalaryGiven"] = Convert.ToDouble(((TextBox)row.Cells[7].FindControl("TxtSalary")).Text);
dr["CreatedDate"] = Convert.ToDateTime(System.DateTime.Now.ToString());
dt.Rows.Add(dr);
}
}
SqlBulkCopy sbc = new SqlBulkCopy(connectionString);
sbc.DestinationTableName = "SalaryDetails";
sbc.WriteToServer(dt);
sbc.Close();
Et ma table de destination ressemble à ceci,
