Working with File Uploads in .NET Core

Handling file uploads is a common requirement in modern web applications, whether it’s profile pictures, documents, or data imports. In .NET Core, working with file uploads is simple and secure thanks to built-in support for multipart form data.

The primary interface for handling uploads is IFormFile, which represents the uploaded file. In your controller, you can accept files by adding an IFormFile parameter to your action method. For example:

[HttpPost("upload")]

public async Task<IActionResult> Upload(IFormFile file)

{

    if (file != null && file.Length > 0)

    {

        var path = Path.Combine("wwwroot/uploads", file.FileName);

        using (var stream = new FileStream(path, FileMode.Create))

        {

            await file.CopyToAsync(stream);

        }

        return Ok("File uploaded successfully!");

    }

    return BadRequest("No file uploaded.");

}

You can also handle multiple files using IFormFileCollection or a list of IFormFile. Always validate file type, size, and sanitize file names to prevent security risks like path traversal attacks.

For large uploads, consider using streaming instead of buffering to improve performance. Additionally, configure limits in Startup.cs with FormOptions or via RequestSizeLimit attribute to manage maximum file size.

By combining proper validation, error handling, and secure storage, .NET Core provides a reliable and efficient way to manage file uploads in web applications.

Would you like me to also add best practices (like virus scanning, cloud storage with Azure/AWS, etc.) to make it more advanced?
