unable to cast object of type 'system.int32' to type 'system.string'

I got the above error, when i tried the below line

int nOut = datatable.Rows.IndexOf(datatable.AsEnumerable().Where(c => c.Field(4) == lblFirst.Value && c.Field(6) == "0").FirstOrDefault());

Hi,

You may need to specify the datatype of columns of datatable accordingly -

int nOut = datatable.Rows.IndexOf(datatable.AsEnumerable().Where(c => c.Field<string>(4) == lblFirst.Value && c.Field<string>(6) == "0").FirstOrDefault());

If it is not string change both sides appropriately.
