Call External Json Webservice From C#?

Jan 15, 2010

I need to make a call to a json webservice from C# Asp.net. The service returns a json object and the json data that the webservice wants look like this:

"data" : "my data"

This is what I've come up with but I can't understand how I add the data to my request and send it and then parse the json data that I get back.

string data = "test";
Uri address = new Uri("http://localhost/Service.svc/json");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
string postData = "{"data":"" + data + ""}";

How can I add my json data to my request and then parse the response?

WebRequest And WebService Call Asynchronously In C#?

Sep 20, 2010

I have MVC application (applies to non MVC as well) where a user is posting in data. I need to take this data, send it off to two seperate end points (one using a WebRequest form POST and one using a Web Service), parse the result, and send the result back to the original user.

The issue at hand is that both end points take about 20-30 seconds to respond (response is a string) which means that I should probably execute these two calls asynchronously. At the same time I want to wait to respond to the original user until I get both results back. I am guessing I might have to use some sort of object lock so the response does not get sent back before the two calls are complete?

Based on the responses I decided to go with async controllers since I am already working with a MVC application.

AJAX :: AutoComeple Does Not Call Webservice?

Feb 17, 2011

I have am trying to implement a simple AutoComplete function yet i am having difficulty. It looks like the AutoComplete control is not even calling the method (webservice). If i load the webservice from the browser, i can see my Method, click on it, enter in the prefix, click on Invoke and it returns a SQL STRING. Below is the string the webservice returns.

<?xml version="1.0" encoding="utf-8"

VS 2010 - Can Call One Webservice Method But Not The Other

Nov 26, 2012

I've enhanced my web service with a new method. If I open a browser and type the url of the service, I get a list of the methods including the new one, so that looks okay.

I have a snippet of code which I paste to a Firebug console to test the method, and I am getting a 500 internal server error. If I use the same snippet of code and modify it to test one of the other methods, that works fine.

What I can look at to figure out what is wrong with this new method? The other weird thing is if I try to run the URL on the server it says The test form is only available for requests from the local machine. But I am on the local machine. So I don't know if something is screwed up there, too, or it's the same cause or what.

I know there's tons of advice on the Internet regarding server 500 errors but this is unique in that my web service is working except for the new procedure.

I think I will write another new procedure that's simple (like Hello World) and see if I can call that. This new method returns a list of objects but so does one of the older methods, so I don't know what would be unusual there

.net - Possible Memory Leak In Asynchronous .NET Call To A WebService?

Sep 16, 2010

I've created a small class library to asynchronously call a WebService(Fire and Forget. I don't need the result).In a Windows Form application, the XXXAsync() method works fine. But, in a Web Application, the process is locked until the XXXCompleted event is fire.My problem is: I tried to create a Delegate and use the Begin/EndInvoke to call the XXXAsync() method. It worked fine, but, the w3wp process seems to be consuming a huge amount of memory. I'm calling the EndInvoke method properly. Invoking the GC.Collect did not free any memory

Kill A Javascript Async Call To A .net Webservice?

Jun 14, 2010

My javascript code is calling a asp.net webservice, so i have a call to the webservice something like this:MyWebservice.GetData(param, ResponseReceived, ResponseTimeOut, ResponseError);When the webservice returns data, ResponseReceived method is called.However sometimes the user might navigate to another url before the webservice call actually returns, in such a scenario FireFox throws an Error saying 'An error occured oricessubg the request. The server method GetData failed'So my question is how can i kill the async call when the user navigates to another page or makes another request to the webservice? I know in a normal XMLHttpRequest i could have called Abort method, but not sure how to make it work with the above webservice proxy.

How To Send A Single Quote As Value In JSON Webservice Call

Feb 17, 2011

I'm trying to make a call to a JSON ASP.NET web service with .NET.

It is ok when I send " { county : 'whatever' } ", but I get a 500 Internal Server error if I try for example " { county : 'It's ok' } ".

[Code]....

I've found some posts with examples but I cannot make it work:

" { county : "whatever" } " and " { "county" : "whatever" } " also works.

But either of " { county : "It's ok" } ", " { county : "It's ok" } " or any other combination that contains a single quote in the variable work.

How can I send a single quote inside a JSON call?
