推荐答案

MVC 6使用了另一种机制来上传文件.您可以在 GitHub 或其他 资源.只需将IFormFile用作操作的参数或文件集合或 IFormFileCollection 如果要同时上传几个文件:

MVC 6 used another mechanism to upload files. You can get more examples on GitHub or other sources. Just use IFormFile as a parameter of your action or a collection of files or IFormFileCollection if you want upload few files in the same time:

public async Task<IActionResult> UploadSingle(IFormFile file) { FileDetails fileDetails; using (var reader = new StreamReader(file.OpenReadStream())) { var fileContent = reader.ReadToEnd(); var parsedContentDisposition = ContentDispositionHeaderValue.Parse(file.ContentDisposition); var fileName = parsedContentDisposition.FileName; } ... } [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)); } ... } }

您可以在 asp中查看IFormFile的当前合同来源.另请参见 ContentDispositionHeaderValue .

You can see current contract of IFormFile in asp sources. See also ContentDispositionHeaderValue for additional file info.
