+# Streams
+
+When reading from a stream, if you need to go back to the beginning of the stream, you can use the `Stream.Position` property.
+
+```cs
+using (var stream = new File.OpenRead("path\\to\\file"))
+using (var reader = new StreamReader(stream))
+{	
+	// Read file content.
+	var content = reader.ReadToEnd();
+
+	// Go back to beginning of the stream.
+	stream.Position = 0;
+
+	// Read file content again.
+	content = reader.ReadToEnd();
+}
+```
+
+When writing to a file, you need to flush the writer for the data to be written to the stream. `StreamWriter` contains an internal buffer and the data is only written to the stream when the buffer is full, or `Flush` is called. `Flush` is automatically called when a `using` block exits.
+
+```cs
+using (var stream = new File.OpenWrite("path\\to\\file"))
+using (var writer = new StreamWriter(stream))
+{	
+	writer.WriteLine("Foo");
+	writer.Flush(); // Data is written from the writer buffer to the stream.
+} // Flush is also called here.
+```
