# IFileService

The `IFileService` interface provides methods for handling file operations, such as downloading and uploading files within the HopFrame web application. It abstracts file-related operations to ensure a smooth and consistent user experience.

## Methods

1. **DownloadFile**
    - Initiates the download of a file with the given name and data.
    - Suitable for dynamically generating and offering files to the user, such as CSV exports or reports.

   ```c#
   Task DownloadFile(string name, byte[] data);
   ```

    - **Parameters:**
        - `name`: The name of the file to be downloaded (including the extension, e.g., "example.csv").
        - `data`: The byte array representing the content of the file.
    - **Usage Example:** Exporting table data as a CSV file for download.

2. **UploadFile**
    - Allows the user to upload a file through the web interface and returns the uploaded file for further processing.
    - This method provides integration with Blazor's `IBrowserFile` for easy file handling.

   ```c#
   Task<IBrowserFile> UploadFile();
   ```

    - **Returns:** An `IBrowserFile` instance representing the uploaded file.
    - **Usage Example:** Importing data from a CSV file to populate or update a table.

## Integration

The `IFileService` is commonly used in conjunction with plugins or components that require file operations, such as the Exporter Plugin, which leverages this service to enable data export and import functionality.

## Key Features

- Streamlines file handling for web applications.
- Simplifies both download and upload processes with minimal code.
- Ensures compatibility with Blazor's file-handling capabilities.

By implementing or extending the `IFileService`, developers can customize the file-handling behavior to suit specific application needs. Let me know if you'd like more examples or details!
