I want to post a file to a web server that will validate and return another file after validation.

This is from the server:

[HttpPost("UploadFile")]
[Route("test")]
public FileInformation CreateGame([FromForm] FileInformation fileInformation)
{
    FileInformation f = new FileInformation();
    f.Name = fileInformation.Name;
    f.Description = fileInformation.Description;
    f.File = fileInformation.File; // the console cannot convert this

    //System.IO.File.WriteAllBytes("wwwroot\", fileInformation.File);
    try
    {
        using (Stream fileStream = new FileStream("wwwroot\" + fileInformation.Name, FileMode.Create))
        {
            fileInformation.File.CopyToAsync(fileStream);
        }
    }
    catch { }

    return fileInformation;
}

public class FileInformation
{
    public string Name { get; set; }
    public string Description { get; set; }
    public IFormFile File { get; set; }
}

This part is from the console application

string filePath = @"TextFile1.txt";

using var form = new MultipartFormDataContent();
using var fileContent = new ByteArrayContent(await File.ReadAllBytesAsync(filePath));

fileContent.Headers.ContentType = MediaTypeHeaderValue.Parse("multipart/form-data");

form.Add(fileContent, "File", Path.GetFileName(filePath));

form.Add(new StringContent("TextFile1.txt"), "Name");
form.Add(new StringContent("TextFile1.txt"), "Description");

var httpClient = new HttpClient()
{
    BaseAddress = new Uri("https://localhost:7009")
};

var response = await httpClient.PostAsync($"/api/UploadScore/test", form);

//response.EnsureSuccessStatusCode();

var responseContent = await response.Content.ReadAsStringAsync();

FileInformation f = JsonConvert.DeserializeObject<FileInformation>(responseContent);

If I populate the File property in fileInformation, the code crashes upon conversion. I can’t figure this out.

I have tried to convert using ReadAsArray.

I want to be able to retrieve a file from the server.
