Question

我的代码是这样的，如何添加前缀，如＆＃34; 123 _＆＃34;当用户上传如1.jpg时，在文件名的前面，然后将其更改为123_1.jpg到服务器？

                  <script type="text/javascript">                                         
                      var uploader = new qq.FileUploader({                            
                            element: document.getElementById('file-uploader'),            
                            allowedExtensions: ["jpg", "pdf"],         
                            template: '<div class="qq-uploader">' +                       
                                      '<div class="qq-upload-drop-area"><span>drag the files to here to upload</span></div>' +
                                      '<div class="qq-upload-button">upload files</div>' +      
                                      '<ul class="qq-upload-list"></ul>' +                  
                                      '</div>',
                            action: '@Url.Action("upload", new { staffId = Model.StaffId })'
                      });
                   </script>

非常简单，

public ActionResult SaveFile(HttpPostedFileBase FileUpload)
    {             
      string fileName = "";
      if (FileUpload != null && FileUpload.ContentLength > 0)
        {
          fileName = "123_"+ Path.GetFileName(FileUpload.FileName);
          //rest code

使用qq.FileUploader上传文件时，如何在文件名中添加前缀字符串
