'的HttpRequest'不包含'文件'的定义

我有一个post方法,其中有一个文件上传控件。要在控制器中获取上传的文件,我收到如下错误:

Error   CS1061  'HttpRequest' does not contain a definition for 'Files' and no extension method 'Files' accepting a first argument of type 'HttpRequest' could be found (are you missing a using directive or an assembly reference?)

我的代码如下:

[ValidateAntiForgeryToken]
        [HttpPost]
        public async Task<IActionResult> TeamUserDetail(TeamUsers model)
        {
            var file = Request.Files[0];
            return View();
        }

在Request.Files [0],它给出了上面显示的错误。 MVC6用于项目。

请指导我。我错过了添加的任何参考吗?

谢谢

MVC 6使用另一种机制上传文件。您可以在GitHubother sources上获得更多示例。只需使用IFormFile作为操作的参数:

public FileDetails UploadSingle(IFormFile file)
{
    FileDetails fileDetails;
    using (var reader = new StreamReader(file.OpenReadStream()))
    {
        var fileContent = reader.ReadToEnd();
        var parsedContentDisposition = ContentDispositionHeaderValue.Parse(file.ContentDisposition);
        fileDetails = new FileDetails
        {
            Filename = parsedContentDisposition.FileName,
            Content = fileContent
        };
    }

    return fileDetails;
}

[HttpPost]
public async Task<IActionResult> UploadMultiple(ICollection<IFormFile> files)
{
    var uploads = Path.Combine(_environment.WebRootPath,"uploads"); 
    foreach(var file in files)
    {
        if(file.Length > 0)
        {
            var fileName = ContentDispositionHeaderValue.Parse(file.ContentDisposition).FileName.Trim('"');
            await file.SaveAsAsync(Path.Combine(uploads,fileName));
        }
    return View();
    }
}

您可以在asp.net sources中看到IFormFile的当前合约。
