C # ASP. NET uses Formdata objects to implement AJAX submission forms and upload images

1. HTML code:

<formID= "Postform">file name:<inputtype= "text"name= "FileName" />File:<inputtype= "File"name= "My_file" />            <inputtype= "button"value= "Submit"onclick= "Btnpost ()" />    </form>

2. jquery Code:

<script>functionBtnpost () {varFormData =NewFormData ($ ("#postForm") [0]); $.ajax ({URL:"/home/post", Data:formdata, type:"POST", Async:false, contentType: false, Processdata:false , success:function(msg) {}, Error:function(e) {}}); }</script>

Attention:

Contenttype:false,------------> In order to upload files, specific Baidu has,
Processdata:false----------->processdata default to False, when set to True, jquery Ajax commits without serializing data, but using data directly

3, CS Code:

 Public actionresult Post ()        {            var name = request.form["filename"];             = request.files["my_file"];            .......        }
