C# 如何使用jquery和asp.net（aspx页面）将上载的pdf、doc、jpg文件保存在文件夹中

我已经试过了，但它不起作用，因为调试器没有命中c#file中的web方法。 C#代码

这是我上传文件时使用的jquery代码。我正在尝试上传一个doc，pdf，jpg类型的文件。请帮助我，因为我是asp.net新手

$(document).ready(function () {
$('.uploadedFile').on('change', function (e) {

    var fileName = "";

    var documentType = $(this).val().split('.').pop().toLowerCase();
    fileName = e.target.files[0].name;

    var data = new FormData();
    var files = $("#" + e.target.id).get(0).files;
    if (files.length > 0) {
        data.append("UploadedImage", files[0]);
    }
