How to parse Multipart Form File

 To parse multipart form using .NET 7, you can use the MultipartFormDataParser class from the Http-Multipart-Data-Parser package1. You can parse the stream containing the multipart/form-data by invoking MultipartFormDataParser.Parse (or it’s asynchronous counterpart MultipartFormDataParser.ParseAsync). Access the data through the parser1.

Here’s an example of how you can parse a multipart/form-data request in .NET 7 using Http-Multipart-Data-Parser package1:

using HttpMultipartParser;
using System.IO;

// ...

var parser = new MultipartFormDataParser(Request.Body);
foreach (var file in parser.Files)
{
    var filename = file.FileName;
    var contentType = file.ContentType;
    var content = file.Data;
    // Do something with the file
}

I hope this helps! Let me know if you have any other questions.
