我在VS 2015中使用ASP.NET 5,MVC 6.我正在制作一个Web应用程序.在我的表格上我有：
<form method="post" enctype="multipart/form-data">
<div id="uploadSection" >
<label >Select files for upload</label>
<input type="file" id="fileSelect" name="fileSelect" multiple />
</div>
<div>
<input type="submit" id="thisbutton" value="button" />
</div>
</form>
在我的控制器中：
[HttpPost]
public async Task<IActionResult> FileForm(Fileviewmodel vm,IFormFile file)
{
if (ModelState.IsValid)
{
//IFormFileCollection files = Request.Form.Files;
string filePath = Path.Combine("C:","transfers");
//foreach (var file in files)
//{
if (file != null && file.Length > 0)
{
var fileName = ContentDispositionHeaderValue.Parse(file.ContentDisposition).FileName.Trim('"');
await file.SaveAsAsync(Path.Combine(filePath,fileName));
}
//}
ModelState.Clear();
}
return View();
}
我有一个更大的表单,其中有母表单字段进入我的Formviewmodel(所有字段都填充它们应该),我实际上尝试将IFormFileCollection,ICollection,IList,List作为上述方法中的参数,而是也直接把它放在我的视图模型中.无论我是作为单个文件还是多个文件,在模型或控制器中,我总是得到null.
‘IFormFileCollecion files = Request.Form.Files’实际上有效,但我不想这样做,因为它应该按照我拥有或拥有它的方式工作.
当我把文件的属性放在我的模型中时,我把“[required]”放在它上面并且它不会触发.
而且,更好的是,我用fiddler多次运行它,它实际上是POST文件 – 所以为什么不将它们投射到模型中？
我的依赖关系错了吗？谁能想到可能导致这种情况的原因？
