How Can I Convert a C# Stream to a Byte Array?

Efficiently Converting C# Streams to Byte Arrays

C# programmers frequently need to transform a Stream object (representing a byte sequence) into a byte[] array. This is essential for tasks like file handling, data transmission, and stream processing.

A Streamlined Approach

A clean and efficient solution is as follows:

<code class="language-csharp">using (var memoryStream = new MemoryStream()) {
  sourceStream.CopyTo(memoryStream);
  return memoryStream.ToArray();
}</code>

This code uses CopyTo to efficiently transfer data from sourceStream to a MemoryStream. The ToArray() method then easily extracts the resulting byte array. This approach is both compact and highly effective.
