Net Core how to use layui multiple file upload

This article mainly introduces the relevant knowledge of how to use layui multi-file upload in .Net Core. The content is detailed and easy to understand, the operation is simple and fast, and it has certain reference value. I believe that everyone will read this article on how to use layui multi-file upload. There are gains, let's take a look at it together.

1. Front-end page

<div class="layui-upload">
      <button type="button" class="layui-btn layui-btn-normal" id="testList">Search</button>
      <div class="layui-upload-list">
            <table class="layui-table">
                <th>File Name</th>
             <tbody id="demoList"></tbody>
   <button type="button" class="layui-btn" id="testListAction" onclick="noFile()">Upload</button>

script section

   layui.use('upload', function () {
        var upload = layui.upload;
        var demoListView = $('#demoList')
             , uploadListIns = upload.render({
                elem: '#testList'
                , url: 'Your file upload interface'
                , accept: 'file'
                , multiple: true
                , size: 30000
                , auto: false
                , bindAction: '#testListAction'
                 , choose: function (obj) {
                      var files = this.file = obj.pushFile(); //Append each selected file to the file queue
                      // read local file
                      obj.preview(function (index, file, result) {
                      var tr = $(['<tr id="upload-' + index + '">'
                                    , '<td>' + file.name + '</td>'
                                    , '<td>' + (file.size / 1014).toFixed(1) + 'kb</td>'
                                    , '<td>Wait to upload</td>'
                                    , '<td>'
                                    , '<button class="layui-btn layui-btn-xs demo-reload layui-hide">reload</button>'
                                    , '<button class="layui-btn layui-btn-xs layui-btn-danger demo-delete">Delete</button>'
                                    , '</td>'
                                    , '</tr>'].join(''));
                                tr.find('.demo-delete').on('click', function () {
                                    delete files[index]; //delete the corresponding file
                                    uploadListIns.config.elem.next()[0].value = ''; //Clear the input file value, so that the file with the same name cannot be selected after deletion
                        , done: function (res, index, upload) {
                            if (res.code == 0) //Upload successful
                                var tr = demoListView.find('tr#upload-' + index)
                                    , tds = tr.children();
                            tds.eq(3).html(''); //clear operation
                            return delete this.files[index]; //Delete files that have been uploaded successfully from the file queue
                        , error: function (index, upload) {

If you come here, it is actually copied from the official website hahaha, the next thing is the key

2. Backend part

Here is the controller part

public async Task<IActionResult> UploadFiles(List<IFormFile> file)
            EditorDataResult editorResult = new EditorDataResult();
            foreach (var formFile in file)
                if (formFile.Length > 0)
                    FileInfo fi = new FileInfo(formFile.FileName);
                    string ext = fi.Extension;
                    var orgFileName = fi.Name;
                    var newFileName = Guid.NewGuid() + ext;
                    var uploads = Path.Combine(_hostingEnvironment.WebRootPath, "You want to upload to the folder");
                    var filePath = Path.Combine(uploads, newFileName);
                    using (var stream = new FileStream(filePath, FileMode.Create))
                        await formFile.CopyToAsync(stream);
                    editorResult.code = 0;

                    editorResult.code = 1;
         JavaScriptSerializer jss = new JavaScriptSerializer();
     string data = jss.Serialize(editorResult);//Convert to Json format!
     return Json(data);

The model part is mainly to call back json data to layui

namespace LayuiMvc.Common.Result
     public class EditorDataResult
         public int code { get; set; }
         public string msg { get; set; }
         public Dictionary<string, string> data { get; set; }

At this point, the file upload is basically done.
