	var records = new List<Dictionary<string, string>>
	{
		new Dictionary<string, string> { { "Id", "1" }, { "Name", "one" } },
		new Dictionary<string, string> { { "Id", "2" }, { "Name", "two" } }
	};
	using (var writer = new StringWriter())
	using (var csv = new CsvWriter(writer))
	{
		var hasHeaderBeenWritten = false;
		foreach (var row in records)
		{
			if (!hasHeaderBeenWritten)
			{
				foreach (var pair in row)
				{
					csv.WriteField(pair.Key);
				}

				hasHeaderBeenWritten = true;

				csv.NextRecord();
			}

			foreach (var pair in row)
			{
				csv.WriteField(pair.Value);
			}
