im trying to Send a File[] to a C# API.

In the same POST request i have other value which get received normaly. Whats the best way to Cast/ Receive an File Object? i could retrieve the .stream() or .arrayBuffer() property, but its a promise and is not fullfilled till im sending the Files.

Is there a C# class / Api i could cast the Files[] in?

This is my API

[Route("CreateJobWithFile")]
[HttpPost]
public Task<ApiResultModel<bool>> CreateJobWithFile(testClass test)
{
    ApiResultModel<bool> result = new ApiResultModel<bool>()
    {
        Data = true
    };
    return Task.FromResult(result);
}

working model

public class testClass
{
    public string Verfahren { get; set; }
    public string Anwendung { get; set; }
    public string Shape{ get; set; }

    public string test4 { get; set; }

    public List<byte[]> Files { get; set; }

    public testClass()
    {
        Files = new List<byte[]>();
    }
}

I tried array of Stream and Byte[] but bot had the Problem that the Promise is not fullfilled
