using System; using System.IO; using Windows.Storage.Streams; class Program { static void Main(string[] args) { MemoryStream stream = new MemoryStream(); DataWriter writer = new DataWriter(stream.AsOutputStream()); uint[] values = { 42, 1337, 65535 }; foreach (uint value in values) { writer.WriteUInt32(value); } writer.FlushAsync(); byte[] data = stream.ToArray(); Console.WriteLine(BitConverter.ToString(data)); } }In this example, we create a MemoryStream object to hold the output data, and wrap it in a DataWriter object using the AsOutputStream method. We then write three unsigned integers to the stream using the WriteUInt32 method, and call FlushAsync to write any remaining data to the output. Finally, we convert the MemoryStream to a byte array and output it to the console. This code example uses the Windows.Storage.Streams package library.
