HttpClient copy data from Request.Form .NET Core - .net-core

Question

I have POST query with Form data with files and I need to send the same data to another POST request.
I'm going to use for this HttpClient class.
Is there a way to copy all Request.Form data and insert them to new request? Or I need to add every param?
I mean something like this:
var httpClient = new HttpClient();
var httpResponseMessage = await httpClient.PostAsync("some_url", Request.Form);

You need to add every param like below:
Model in ProjectA:
public class FormData
{
public int Id { get; set; }
public IFormFile File { get; set; }
public string Name { get; set; }
}
View in ProjectA:
#model FormData
<form asp-action="Post" enctype="multipart/form-data">
<div>
Id:<input asp-for="Id"/>
</div>
<div>
Name:<input asp-for="Name"/>
</div>
<div>
FIle:<input asp-for="File" />
</div>
<div>
<input type="submit" value="create" />
</div>
</form>
Controller in ProjectA:
[HttpPost]
public async Task<IActionResult> Post(FormData formData)
{
HttpClient client = new HttpClient();
// var formData = HttpContext.Request.Form;
client.BaseAddress = new Uri("http://localhost:63331");//your applicationUrl
client.DefaultRequestHeaders.Accept.Clear();
var multiContent = new MultipartFormDataContent();
var file = formData.File;
if (file != null)
{
var fileStreamContent = new StreamContent(file.OpenReadStream());
multiContent.Add(fileStreamContent, "File", file.FileName);
}
multiContent.Add(new StringContent(formData.Id.ToString()), "id");
multiContent.Add(new StringContent(formData.Name.ToString()), "name");
var response = await client.PostAsync("/api/values", multiContent);
//do your stuff...
return Ok();
}
Model in ProjectB:
public class FormDataModel
{
public int Id { get; set; }
public IFormFile File { get; set; }
public string Name { get; set; }
}
Controller in ProjectB:
[HttpPost]
public void Post([FromForm]FormDataModel model)
{
//...
}
Result:
