API built in dotnet core and for file Upload I use IFormFile

When I post file in backend but file not post. I try different way but not success.

My C# model like as below.

public class SaveDisputeViewModel
{
    public string DisputeDescription { get; set; }
    public List<SaveAttachment> Attachments { get; set; }
}

public class SaveAttachment
{
    public string AttachCode { get; set; }
    public IFormFile File { get; set; }
}
