Stream Extension Class

This extension class is useful when you want to create a stream from some bytes of directly from a string

public static class StreamExtender
{
    /// <summary>
    /// Create a stream from an array of bytes
    /// </summary>
    /// <param name="streamBytes">Bytes source foe the stream</param>
    /// <returns></returns>
    public static MemoryStream CreateStreamFromBytes(this byte[] streamBytes)
    {
        var stream = new MemoryStream();
        stream.Write(streamBytes, 0, streamBytes.Length);
        stream.Seek(0, 0);
        return stream;
    }

    /// <summary>
    /// Create a stream from a string
    /// </summary>
    /// <remarks>Useful for unit testing file storage</remarks>
    /// <param name="contents">The contents to be placed in the stream</param>
    /// <returns>A memory stream with the string as contents</returns>
    public static MemoryStream CreateStreamFromString(this string contents)
    {
        byte[] encodedStreamBytes = Encoding.UTF8.GetBytes(contents);
        var stream CreateStreamFromBytes(encodedStreamBytes);
        return stream;
    }
