webmethod

问题 I have a page that uses Ajax Page Methods. When the page first loads, the user is prompted to select a year. This is the only time that a PostBack occurs. The year is stored in a private static page-level integer property named SelectedYear. There are several page methods that pass data from the client to the server, but the year is always stored on the server, so that it won't have to be to be passed in again. The problem is, in a few cases, within the server WebMethod, the SelectedYear

问题 EDITED: I got stuck while getting value of a JSON object in vb.net. My JSON request posts data like given below: function submitEmail() { var ClientsPersonalInfo = { FullName: $("#FullName").val(), PhoneNumber: $("#PhoneNumber").val(), EmailAddress: $("#EmailAddress").val(), DOB: $("#DOB").val(), Occupation: $("#Occupation").val(), NINumber: $("#NINumber").val(), FullAddress: $("#FullAddress").val() } var ClientsData = {}; ClientsData.ClientsPersonalInfo = ClientsPersonalInfo; var d = '{

问题 I'm using FullCalendar (http://arshaw.com/fullcalendar/) and I need help with passing data using json to a c# function in the code behind page of my ASP.net page. I am using json to load data like so in my FullCalendar web application: Code behind: [WebMethod] public static List<Event> GetEvents() { List<Event> events = new List<Event>(); events.Add(new Event() { EventID = 1, EventName = "EventName 1", StartDate = DateTime.Now.ToString("MM-dd-yyyy"), EndDate = DateTime.Now.AddDays(2).ToString

问题 This works: through jQuery I'm using a jQuery.ajax(..) call to a page e.g. Default.aspx/GetStatus having a WebMethod attribute: // Default.aspx [WebMethod()] static public bool GetStatus(long id) { //... The JSON response contains the correct boolean value in the format { d: true } . However I don't understand the origin of the resulting "d" member name. Where does the "d" identifier come from (how is it decided) and how can I change its name? 回答1: What does .d in JSON mean? 来源： https:/

问题 I seem to have a simple scenario but I can't get it to work... I have an ASPX page with code behind. I want to access the Web Methods in the code behind. To do this I added a subscriber in my app.component.ts that calls the service which returns an observable. The service should call my web method. Here's my code: service.component.ts import { Injectable } from '@angular/core'; import { Http, Response, RequestOptions, RequestMethod } from '@angular/http'; import { Observable } from 'rxjs

问题 I don't think I'm exceeding the MaxJsonLength, but I'm still getting "Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property". I checked to see how long the result is, and it's 25,000 rows. I checked the average length of each row by outputting a smaller result, and the average row is 48.5 characters long. 25,000 * 48.5 characters = 1,224,140 characters. MS says that maxJsonLength is in

问题 Is it possible for a C# WebMethod to accept a different parameter name than its client sends? For example, given a client sending this message: <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <GetStatus xmlns="http://example.com/"> <Arg1>5</Arg1> <Arg2>3</Arg2> </GetStatus> </soap:Body> </soap:Envelope> Can the existing
