我创建了一个使用 FormData 将文件上传到 Web API 控制器的组件。
如何从 MultipartMemoryStreamProvider 获取字节数组形式的文件内容？
这是Web Api方法
public Task<IEnumerable<FileModel>> Post()
{
if (Request.Content.IsMimeMultipartContent())
{
var streamProvider = new MultipartMemoryStreamProvider();
var task = Request.Content.ReadAsMultipartAsync(streamProvider).ContinueWith<IEnumerable<FileModel>>(t =>
{
if (t.IsFaulted || t.IsCanceled)
{
throw new HttpResponseException(HttpStatusCode.InternalServerError);
}
FileDataBO filedata;
var fileInfo = streamProvider.Contents.Select(i => {
//save to db
filedata = new FileDataBO ();
filedata.FileName = i.Headers.ContentDisposition.FileName;
filedata.FileType = "jpeg";
// HOW TO GET FILE CONTENT HERE??? IT SHOULD BYTE[]
//filedata.FileContent = ???
//TODO
//_fileDataService.SaveFile(filedata);
return new FileModel(i.Headers.ContentDisposition.FileName, 2048);
});
return fileInfo;
});
return task;
}
else
{
throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotAcceptable, "This request is not properly formatted"));
}
}
您应该能够通过执行以下操作来获取内容i.ReadAsByteArrayAsync()
