Question

我的当前代码如下，仅下载文件。如何在浏览器中查看所有文件类型？

[HttpGet]
    //[NoCacheHeader()]
    [Route("api/image/files")]
    public HttpResponseMessage GFiles(string ImageName)
    {
        var response = Request.CreateResponse(HttpStatusCode.OK);
        var path = "~/Image/" + ImageName;

            path = System.Web.Hosting.HostingEnvironment.MapPath(path);
            var ext = System.IO.Path.GetExtension(path);

            var contents = System.IO.File.ReadAllBytes(path);

            System.IO.MemoryStream ms = new System.IO.MemoryStream(contents);

            response.Content = new StreamContent(ms);

            //

            response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
            response.Content.Headers.ContentDisposition.FileName = ImageName;
            //

            response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("Image/" + ext);
            return response;

    }

我找到了仅适用于pdf和图像的解决方案。只需在MediaTypeHeaderValue中添加MIME类型，并确保ContentDispositionHeaderValue为＆＃34; inline＆＃34;

 response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("inline");

for pdf：

response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");

图片：

response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("images/jpeg");

根据图片类型改变您的MIME。对于microsoft文档，在mediaheadervalue中使用它的mime类型，然后在google chrome中安装离线google docs扩展

如何在浏览器中打开文件而不是使用ASP.NET WebApi下载？
