Working with Files and Directories in .NET and C#

Every robust application needs to interact with the file system, whether it is reading configuration files, writing logs, or organizing user uploads. Master the essentials of file manipulation in .NET using C# and the powerful System.IO namespace. Through clear explanations and practical code examples, you will transition from a beginner to confidently handling path resolution, directory structures, and file streams. You will learn to write clean, secure, and highly performant file-handling code using modern C# features. What you'll learn: Understand the core concepts of the file system and the System.IO namespace; Create, move, rename, and delete files and directories safely using C#; Work with paths correctly across different operating systems using modern path APIs; Read and write file data efficiently using streams, readers, and writers; Apply asynchronous file operations to keep your applications responsive; Handle common file system exceptions and implement proper resource cleanup. The course begins with foundational concepts of file systems and path formats, then guides you step-by-step through basic file operations, streaming large data sets, and implementing modern asynchronous practices. This course is designed for beginner C# developers and .NET programmers who want to master file system integration. No prior experience with file handling is required.
