如何在我对Get请求的响应中使用c＃创建multipart / form-data类型的内容

Question

I have to populate the content object present inside HttpResponseMessage which the content-type = multipart/form-data . I want to send a file and a string in the response content.

Answer 1

in the view the form tag should be something like:-

<form id="formContent" method="post" enctype="multipart/form-data" action="controller/actionMethod">

and the file upload components should be like:-

<input type="file" id="file1Upload" size="50" name="files" />
<input type="file" id="file2Upload" size="50" name="files" />

in the controller, the signature should be like this:-

public string actionMethod(object model, IEnumerable<HttpPostedFileBase> files)
{

foreach (var file in files)
{
  //write here what do you want to do with each file
}
 ....
}

notice IEnumerable<HttpPostedFileBase> files is just added in the signature

hope this helps
