Question

I just want to round the value which comes from datatable,Data comes from SQL to datable.Also datatable have null values i guess this the problem but please also you check for me

string Maxmonthlytable = Math.Round((decimal)monthlytable.Rows[u][3], 2, MidpointRounding.AwayFromZero).ToString();

I get the error ” when casting from a number the value must be a number less than infinity “

Answer 1

You could try:

decimal num = 0;
if (monthlytable.Rows[u][3] != DBNull.Value)
    num = Math.Round((decimal)monthlytable.Rows[u][3], 2, MidpointRounding.AwayFromZero)
string Maxmonthlytable = num.ToString();
