Spargine is a collection of open-source assemblies and NuGet packages designed for .NET 10, which I have been developing and maintaining since the release of .NET Framework 2. These assemblies are not only a core part of my projects but are also actively deployed in production environments across several companies I collaborate with.

Introducing the TempFileManager

The TempFileManager is a powerful utility designed to create and manage temporary files efficiently. It simplifies file management for various use cases, such as unit testing, benchmarking, and work-related tasks.

Automatic Cleanup with IDisposable

TempFileManager implements IDisposable, ensuring that all managed temporary files are automatically deleted when the instance is disposed. This helps free system resources efficiently and prevents orphaned files from accumulating.

Key Features and Methods

The TempFileManager provides several essential methods to streamline temporary file creation and cleanup:

• CreateFile() – Generates a new temporary file and returns its full path.
• CreateFiles(int count) – Creates a specified number of temporary files and returns their paths in a ReadOnlyCollection<string>.
• DeleteAllFiles() – Deletes all temporary files managed by the instance, ensuring a complete cleanup.
• DeleteFile(string fileName) – Removes a specific temporary file by name, allowing precise control over file management.
• GetManagedFiles() – Returns a ReadOnlyCollection<string> containing all currently managed files for inspection or further processing.

Example Usage

Here is a simple example demonstrating how to use TempFileManager:

using (var manager = new TempFileManager())
{
    var files = manager.CreateFiles(50);

    foreach (var file in files)
    {
        // Access or modify the file
    }
}

Best Practices

• Always use TempFileManager within a using statement to ensure proper disposal.
• If you use TempFileManager as a class-level field, implement IDisposable in your class to ensure cleanup.

Why Use TempFileManager?

This utility is an invaluable tool for projects that require temporary file handling, especially in automated tests where frequent file creation and cleanup are necessary. By integrating TempFileManager, you can streamline temporary file management, reduce resource waste, and enhance the reliability of your applications.
