i am facing a problem in auto increment,
it increments month by one but not the way i want ..
I want the month number should be increment each time in for loop,but here in my code it increments for 1 time and rest of the entries are same ..
output should be:if current date is 13/3/2014
then--for i=0 > 13/4/2014
i=1 > 13/5/2014
i=2 > 13/6/2014...

here i my code..

C#
for (int i = 0; i <= int.Parse(txt_bank1.Text); i++)
            {
              
                DateTime InstallDate =Convert.ToDateTime(txt_dated.Text);
               
                DataTable dt = conn.filldatatable("ERP.sp_InstallmentMaster_Insert '" + txt_enqno.Text + "'," + Convert.ToDecimal(txt_monthInstall.Text) + ",'" + InstallDate + "','0'," + Convert.ToDecimal(txt_monthInstall.Text) + ",'True'");

            }


please do suggest a better way.

Start by moving some of the code outside the loop:
C#
decimal month;
if (!decimal.TryParse(txt_monthInstall.Text, out month))
    {
    // Report input problem to user
    }
else
    {
    DateTime InstallDate;
    if (!DateTime.TryParse(txt_dated.Text, out InstallDate))
        {
        // Report input problem to user
        }
    else
        {
        for (int i = 0; i <= int.Parse(txt_bank1.Text); i++)
            {
            conn.filldatatable("ERP.sp_InstallmentMaster_Insert '" + txt_enqno.Text + "'," + month + ",'" + InstallDate + "','0'," + month + ",'True'");
            month++;
            }
        }
    }
Then, find a way to do that that doesn't involve concatenating strings: Never concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.

i appreciate it ,but i have solved it by easy way ..

{
DateTime dtchk = Convert.ToDateTime(txt_dated.Text);

DateTime InstallDate = dtchk.AddMonths(1);

DataTable dt = conn.filldatatable("ERP.sp_InstallmentMaster_Insert '" + txt_enqno.Text + "'," + Convert.ToDecimal(txt_monthInstall.Text) + ",'" + InstallDate + "','0'," + Convert.ToDecimal(txt_monthInstall.Text) + ",'True'");
txt_dated.Text = InstallDate.ToString();
}
