StreamedFileStream

StreamedFileStream is a class in the .NET Framework that allows for efficient handling of large files. It is part of the System.IO namespace and is designed to read and write file contents in a streaming fashion, meaning data is processed in chunks rather than loading the entire file into memory. This approach is crucial for managing memory usage when dealing with files that may exceed available RAM.

The primary benefit of using StreamedFileStream is its ability to avoid out-of-memory exceptions and improve performance for large file operations. It provides methods for reading bytes, writing bytes, seeking within the file, and other standard stream operations. Unlike loading a file entirely into a byte array, StreamedFileStream operates on a sequence of bytes, making it suitable for scenarios such as uploading or downloading large files, processing log files, or working with databases that store binary data.

When interacting with StreamedFileStream, it is important to manage the stream correctly by disposing of it once it is no longer needed. This ensures that system resources, such as file handles, are released promptly. The class is often used in conjunction with other .NET I/O classes to build robust file processing applications. Its implementation ensures that file access is done in a controlled and memory-conscious manner.
