Solution 2

create an array of email then return the array and then you can print it out using for loop in single column

Solution 3

If you would like to return all emails, try this:

C#

StringBuilder sb = new StringBuilder();
while (reader.Read())
{
     sb.Append(reader[0].ToString() + "; ");
}
return sb.ToString();

Above code should return a list of emials separated by ";", for example: "JohnDoe@g.com; JaneDoe@h.com; ...; AliBabaAnd40Robbers@z.com"

For further details, please see: StringBuilder Class (System.Text)[^]
