How to Write a Byte Array to a File in C#?

Writing Byte[] Arrays to Files in C

Problem:
A received byte array, representing a complete file, needs to be written to a file. However, the FileStream class does not accept a byte array or another Stream object as an argument for writing.

Solution:

The simplest method for writing a byte array representing a complete file to a file in C# is to use the File.WriteAllBytes method. This method takes a file path and a byte array as its parameters, and writes the contents of the byte array to the specified file.

File.WriteAllBytes("path/to/file.ext", byte_array);

Implementation:

To implement this solution, you can separate the receiving and processing tasks into different threads. The receiving thread can read the stream from the client and save it to a byte array. Once the byte array is complete, it can be passed to a separate thread for processing.

The processing thread can then use the File.WriteAllBytes method to write the byte array to a file:

// In a separate thread

File.WriteAllBytes("path/to/file.ext", received_byte_array);

This approach allows the receiving thread to continue receiving streams from the client while the processing thread handles writing the files to disk.
