나는 데이터 테이블 및 SqlBulkCopy의를 통해 그 데이터 테이블을 삽입하려고하지만 어떻게 든 나를 위해 작동하지 않는 것을 만들었습니다 .... 제가 오류가 발생했습니다 SqlBulkCopy의이 작동하지 않는 것 나를
,The given value of type DateTime from the data source cannot be converted
to type decimal of the specified target column.
내 데이터 소스이며,
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();
그리고 내 대상 테이블은 다음과 같습니다,
