我需要将asp.net文件的值上传到Ajax参数中

Question

I need to get the value of an asp.net fileupload into Ajax parameter and i'm trying to do like this:

$('#<%=fileUpload.ClientID%>').val() 

//and in the WebMethod  
[WebMethod]
public static List<AjaxCategory> AddCategory(FileUpload categoryImage)

I don't know if it is possible or not, but like this is not working

Answer 1

Async file upload requires some additional setup. Look to using a utility like:

• AJAX control toolkit AsyncFileUpload
• Uploadify
• HTML 5 File API (also here )
• Others
