Project 01

File Stream Copier

This project demonstrates how to efficiently copy files using FileStream operations in C#, wrapped in a user-friendly Windows Forms interface. The tool provides both automatic and manual destination path options, with comprehensive validation and error handling to ensure reliable file operations. The project was built to understand file I/O fundamentals in .NET while creating a practical desktop utility.

Technical

Highlights

  • Built a Windows Forms application with source/destination path selection and an auto-path generation feature using checkboxes.

  • Opened source and destination files using FileStream wrapped in using statements to ensure deterministic disposal of system resources.

  • Implemented path validation logic including empty path checks, file existence verification, and same-file collision prevention.

  • Leveraged .NET's built-in buffered streaming via CopyTo() to transfer file contents in fixed-size chunks, avoiding memory issues with large files while benefiting from framework-optimized buffer management.

  • Added dynamic UI controls that enable/disable based on user selections (checkbox state management).

  • Implemented comprehensive exception handling with user-friendly MessageBox feedback.

Takeaways

  • Gained hands-on experience with FileStream operations and proper resource management using using statements.

  • Developed understanding of Windows Forms event-driven programming and UI state management.

  • Learned importance of path validation, including case-insensitive path comparison and full path resolution.

  • Built practical understanding of how file I/O works in .NET with automatic buffer management.

  • Understood the critical role of proper resource disposal to prevent file locks and memory leaks
