+###### Example
+
+```cs
+void Main()
+{
+	var records = new List<Foo>
+	{
+		new Foo { Id = 1, Name = "one" },
+	};
+
+	// Write to a file.
+	using (var writer = new StreamWriter("path\\to\\file.csv"))
+	using (var csv = new CsvWriter(writer, CultureInfo.InvariantCulture))
+	{
+		csv.WriteRecords(records);
+	}
+
+	records = new List<Foo>
+	{
+		new Foo { Id = 2, Name = "two" },
+	};
+
+	// Append to the file.
+	var config = new CsvConfiguration(CultureInfo.InvariantCulture)
+	{
+		// Don't write the header again.
+		HasHeaderRecord = false,
+	};
+	using (var stream = File.Open("path\\to\\file.csv", FileMode.Append))
+	using (var writer = new StreamWriter(stream))
+	using (var csv = new CsvWriter(writer, config))
+	{
+		csv.WriteRecords(records);
+	}
+}
+
+public class Foo
