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

Using this solution i created an extension.

/// 

/// 
/// 
/// 
/// 
/// if null/empty will use IO.Path.GetTempPath()
/// will use csv by default
public static void ToCsv(this IDataReader reader, string filename, string path = null, string extension = "csv")
{
    int nextResult = 0;
    do
    {
        var filePath = Path.Combine(string.IsNullOrEmpty(path) ? Path.GetTempPath() : path, string.Format("{0}.{1}", filename, extension));
        using (StreamWriter writer = new StreamWriter(filePath))
        {
            writer.WriteLine(string.Join(",", Enumerable.Range(0, reader.FieldCount).Select(reader.GetName).ToList()));
            int count = 0;
            while (reader.Read())
            {
                writer.WriteLine(string.Join(",", Enumerable.Range(0, reader.FieldCount).Select(reader.GetValue).ToList()));
                if (++count % 100 == 0)
                {
                    writer.Flush();
                }
            }
        }

        filename = string.Format("{0}-{1}", filename, ++nextResult);
    }
    while (reader.NextResult());
}
