DataReader to .CSV with column names

Question

I\'m generating a csv file from an SqlDataReader, however it is not writing the column names, how can I make it write them? The code I\'m using is as follows:

Answer 1

Read all the column names and append it to sb then iterate reader.

SqlDataReader reader = cmd.ExecuteReader();
StringBuilder sb = new StringBuilder();

//Get All column 
var columnNames = Enumerable.Range(0, reader.FieldCount)
                        .Select(reader.GetName) //OR .Select("\""+  reader.GetName"\"") 
                        .ToList();

//Create headers
sb.Append(string.Join(",", columnNames));

//Append Line
sb.AppendLine();

while (reader.Read())
....
