Send file with ajax of jQuery to web service in C# (asmx) -


i'm using web service method:

        $.ajax({             type: 'post',             url: 'page.asmx/method',             contenttype: 'application/json; charset=utf-8',             datatype: 'json',             data: '{}'         });

sending json string, , works, if try append formdata content of input , passing in data value have 500 response. have do?

you need serialize data....

  var data = new formdata();    var files = $("#youruploadctrlid").get(0).files;    // add uploaded image content form data collection   if (files.length > 0) {        data.append("uploadedfile", files[0]);   }    // make ajax request contenttype = false, , procesdate = false   var ajaxrequest = $.ajax({        type: "post",        url: "/api/fileupload/uploadfile",        contenttype: false,        processdata: false,        data: data        });

and inside controller can have like

if (httpcontext.current.request.files.allkeys.any()) {    // uploaded image files collection    var httppostedfile = httpcontext.current.request.files["uploadedfile"];     if (httppostedfile != null)    {    // validate uploaded image(optional)     // complete file path        var filesavepath = path.combine(httpcontext.current.server.mappath("~/uploadedfiles"), httppostedfile.filename);      // save uploaded file "uploadedfiles" folder     httppostedfile.saveas(filesavepath); }  }

hope helps...
