我正在将多部分表单数据发送到我的WebApi控制器.我感兴趣的内容包括图像和另一个非图像值.我可以读取图像没问题,但无法弄清楚如何读取用户名部分(以andy作为值).它不在提供程序的FormData属性中.我怎么才能得到它？

控制器代码

string root = System.Web.HttpContext.Current.Server.MapPath("~/App_Data");
MultipartFormDataStreamProvider provider = new MultipartFormDataStreamProvider(root);

var task = request.Content.ReadAsMultipartAsync(provider).ContinueWith<HttpResponseMessage>(o =>
{ 
    ...
}
