看到http://www.asp.net/web-api/overview/formats-and-model-binding/html-forms-
and-multipart-
mime#multipartmime，尽管我认为这篇文章使它看起来比确实是。
基本上，
public Task<HttpResponseMessage> PostFile() { HttpRequestMessage request = this.Request; if (!request.Content.IsMimeMultipartContent()) { throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType); } string root = System.Web.HttpContext.Current.Server.MapPath("~/App_Data/uploads"); var provider = new MultipartFormDataStreamProvider(root); var task = request.Content.ReadAsMultipartAsync(provider). ContinueWith<HttpResponseMessage>(o => { string file1 = provider.BodyPartFileNames.First().Value; // this is the file name on the server where the file was saved return new HttpResponseMessage() { Content = new StringContent("File uploaded.") }; } ); return task; }
