Hi,

I have a DataTable in below format.

A B C D
1 1 1 1
2 2 2
3 3
4 4 4 4

I am using VB.NET as language.

I want a LINQ query which replaces the NULL values to 0 (Zero) in one shot. (or any easy way)

Any idea?

Thanks,
Naimish

0	var allrows=dt.AsEnumerable().Select(delegate(DataRow r) { DataRow nr = dt.NewRow(); foreach (DataColumn item in dt.Columns) { nr.SetField(item.ColumnName, r[item.ColumnName] is DBNull ? 0 : r[item.ColumnName]); } return nr; } Naimishforu, if this helps please login to Mark As Answer. \| Alert Moderator

var allrows=dt.AsEnumerable().Select(delegate(DataRow r)

            {

                DataRow nr = dt.NewRow();

                foreach (DataColumn item in dt.Columns)

                {

                    nr.SetField(item.ColumnName, r[item.ColumnName] is DBNull ? 0 : r[item.ColumnName]);

                }

                return nr;

            }
