How to find out whether SqlCe query Has rows?

Question

In my simple db I use SqlCE and I cannot figure out how to correctly find out whether the query returns rows or not. HasRows does not work. So far I have this:

_DbCommand.CommandText="SELECT * FROM X"
SqlCeDataReader reader=_DbCommand.ExecuteQuery();

if (reader.FieldCount!=0) //I thought it could work (O rows - 0 fields?), but its true even with 0 rows
{
    while (reader.Read())
    {
        //
    }
}

Thanks

Answer 1

Try this:

_DbCommand.CommandText="SELECT COUNT(*) FROM X"
Int32 count = (Int32) _DbCommand.ExecuteScalar();

Answer 2

int count = 0;
while (reader.Read())
{
 count++;
}
if(count==0)
{
 // no rows
}
