将文件从WPF应用程序上传到Web API [英] Uploading a file from a wpf application to a web api

问题描述

我正在尝试将文件(图像)从WPF应用程序上传到Web Api控制器.在控制器中，我将文件转换为位数组并将其保存在DB中.我使用以下代码将文件发送到Web api

I am trying to upload a file (image) from a WPF application to a Web Api controller. In the controller I convert the file into a bit array and save it in a DB. I used the following code for sending files to web api

var client = new WebClient();
client.UploadFile("URI", "POST", "filepath");

在我的Web API中，我正在检查传入的请求是否为MimemultipartContent

In my web api I am checking if the incoming request is MimemultipartContent

if (Request.Content.IsMimeMultipartContent())

这很好.但是，当我尝试发送数据缓冲区而不是文件时，我陷入了如何编写服务器端代码的麻烦.

This works fine. But when I try to send a data buffer instead of a file I am stuck how to write my server side code.

var bytes = File.ReadAllBytes('filepath');
client.UploadData("URI", "POST", bytes);

推荐答案

知道了.其实很简单.

        var task = Request.Content.ReadAsByteArrayAsync();
        var bytes = task.Result;
        Image img = new Image();
        img.Id = Guid.NewGuid();
        img.ImageData = bytes;
        db.Images.Add(img);
        db.SaveChanges();
