Consuming .asmx service in asp.net web api application

I am consuming the .asmx service in my asp.net web api application like this :
[
but this service returns nothing, but in turn writes response in HTTP response object like this:
` [WebMethod(EnableSession = true)]
[ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
public void GetResearchDocsBySector(int pageCode, int resultsPerPage, string subTypeIds, int timeframe)
{
JavaScriptSerializer js = new JavaScriptSerializer();
IRatingsDirectDataMgr dataMgr = RemoteUtil.GetRemote();
List<ResearchDocumentDisplay> results = dataMgr.GetSolrResults(pageCode, resultsPerPage, subTypeIds, timeframe, false);
List<ResearchDocumentWidgetDisplay> resultList = new List<ResearchDocumentWidgetDisplay>();
foreach (var item in results)
{
var obj = ObjMapper<ResearchDocumentDisplay, ResearchDocumentWidgetDisplay>.Map(item);
obj.ArticleTypeName = Constants.TypeMappings[obj.ArticleTypeId];
resultList.Add(obj);
}
HttpContext.Current.Response.Write(js.Serialize(resultList));
}`
I want to consume the result obtained from the service in my webapi application in json format how can we go about it ?
Note : I can't change the .asmx service code at all !!

Set GetResearchDocsBySector to return your List rather than having a void return type and injecting it into the Current http content. TO do this you will need to mark ResearchDocumentWidgetDisplay as Serialisable which you do by adding [Serialisable] above your class ResearchDocumentWidgetDisplay.

.NET - Access webservice (.asmx) method using WebRequest in c#?

I got a .net project from client. Right now, I need to make a WebRequest to a WebService (.asmx). The problem is i dont know how call the method in that web service using web request from c#.
my code :
RunRoutines.aspx
string UseAddress = "http://localhost:31952/api/RunRoutines.asmx";
string address = string.Format(UseAddress);
HttpWebRequest httpRequest = (HttpWebRequest)WebRequest.Create(address);
RunRoutines.asmx
public class RunRoutines : System.Web.Services.WebService
{
[WebMethod]
public string RunRR1()
{
return "Hello World";
}
}
I need to access the RunRR1() method from the web request in RunRoutines.aspx. Please advise. Thanks!

Well you can access it using the name of the reference you have given while adding service reference.
For example if it is localHost then you can try below code:
var yourService = new localHost.WebService();
yourService.RunRR1();

I have set up a web service but have no idea how to get data from it in MVC 5 c#

I have the following namespace for the web service and I can see lots of functions I can access...
using MyService.api;
public class HomeController : Controller
{
public ActionResult Index()
{
//What needs to go here?
// LoginRequest and Response are types from the web service reference
LoginRequest loginRequest = new LoginRequest();
loginRequest.user = "blah";
loginRequest.password = "abc1234";
LoginResponse loginResponse = new LoginResponse();
string sessionID = loginResponseSession.session.sessionId; // This has nothing in it
return View("Index", sessionID );
}
...
the api exposes all of these methods, things like:
MachineRequest machineRequest = new MachineRequest();
string[] machines = machineRequest.machines;
But ofcourse when I call that, it does not magically go and collect machines from the url.
How do I make and respond to the requests? What is the Service reference actually for?

Your question is a bit unclear. If you've generated a WCF service reference, you can use the "proxy" or "client" like this:
var client = new MyService.api.ApiReferenceClient();
var loginResponse = client.LoginRequest(loginRequest);
That will perform the SOAP call (or whatever binding is being used).

Accessing list from Sharepoint Webservice with Sharepoint Online 2013

I am trying to access a list from sharepoint via the web services.
I have tried lots of different web reference URLS for my web service.
The list is found at :
example.com/sites/dms/_layouts/15/start.aspx#/Lists/Documents/AllItems.aspx
the Web service URL I am using now is
https://example.com/sites/dms/_vti_bin/lists.asmx
Obviously example.com is not the real URL.
when I run the code
service.GetList("Documents");
I get the error:
List does not exist.
The page you selected contains a list that does not exist. It may have been deleted by another user.
0x82000006
My full code (many things are just for testing purposes):
public void UpdateList()
{
MKLists.Lists service = GetService();
string targetSite = "https://mywebpage.com/sites/dms";
using (ClientContext ctx = ClaimClientContext.GetAuthenticatedContext(targetSite))
{
if (ctx != null)
{
ctx.Load(ctx.Web); // Query for Web
ctx.ExecuteQuery(); // Execute
string test = (ctx.Web.Title);
}
}
CookieCollection authCookie = ClaimClientContext.GetAuthenticatedCookies(targetSite, 925, 525);
service.CookieContainer = new CookieContainer();
service.CookieContainer.Add(authCookie);
XmlNode tester = service.GetList("Documents");
}
private MKLists.Lists GetService()
{
MKLists.Lists myService = new MKLists.Lists();
myService.Credentials = System.Net.CredentialCache.DefaultCredentials;
return myService;
}

change this line:
MKLists.Lists service = GetService();
with
MKLists.Lists service = new MKLists.Lists();
i hope this helps.
Edit
according to your comment in the answer here is the update #Michael
try changing your targetsite url to
string targetSite = "https://mywebpage.com/sites/dms/_vti_bin/Lists.asmx";
hope this time it helps

IT turns out it was to do with the subsites.. and this line solved it:
service.Url = "https://mywebpage.com/sites/dms/_vti_bin/lists.asmx";

I've found some users with the same issue.
They said that these links below solved that issue. Could you try it?

Android -- How to access data in an ASP.NET database via app?

I have a Windows web server already set up with a website (unlimited application pools) and I want to be able to access a database on that server via the Android app I'm developing. How can I do this? Can someone point me to a tutorial or give code example of how this cross-platform (Android/Java to ASP.NET/C#) communication can be done?
(I'm trying to create a leader board or global scoreboard for my Android game on my server.)
Thanks.

Your app should expose a webservice.
There is no native support for .net soap based webservices. But you can use the ksoap android port:
http://code.google.com/p/ksoap2-android/
which allows an android app to consume a .net asmx webservice.
However the deserialisation of complex on the client side involves lot of code writing for every object you want so pass to the client.
I tried it for a project and there were some problems I ran into (either I could get result back to the client but the parameters i passed where always null or the other way - I could pass arguments but the result was null).
Here is an example I posted for getting an int: How to call a .NET Webservice from Android using KSOAP2?
However, from my current knowlege I would suggest using a .asmx webservice that returns a json string and use a java json serialiser to parse the output. The advantages:
Write less code
Faster, since mobile devices don't always have good internet connections and the xml overhead from soap is bigger than json.
Quickstart:
Create a new asmx Webservice in your .net webapp.
Include a reference to System.Web.
Decorate your webservice class with [ScriptService] and your method with [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
[ScriptService]
public class WebService1 : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string HelloAndroid()
{
return "Hello Android";
}
}
(I think you have to add a reference to System.Web.Extension.dll which is available since .net 3.5).
Your webservice will still return XML (so you can use it with a soap client) unless you make a HTTPPost request with content-type "application/json".
use this code to contact the webservice from android:
private JSONObject sendJsonRequest(string host, int port,
String uri, JSONObject param)
throws ClientProtocolException, IOException, JSONException
{
HttpClient httpClient = new DefaultHttpClient();
HttpHost httpHost = new HttpHost(host, port);
HttpPost httpPost = new HttpPost(uri);
httpPost.addHeader("Content-Type", "application/json; charset=utf-8");
if (param != null)
{
HttpEntity bodyEntity = new StringEntity(param.toString(), "utf8");
httpPost.setEntity(bodyEntity);
}
HttpResponse response = httpClient.execute(httpHost, httpPost);
HttpEntity entity = response.getEntity();
String result = null;
if (entity != null) {
InputStream instream = entity.getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(instream));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
sb.append(line + "\n");
result = sb.toString();
instream.close();
}
httpPost.abort();
return result != null ? new JSONObject(result) : null;
}
if your webservice methods looks like this:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public User GetUser(string name, int age)
{
return new User { Name = name, Age = age; }
}
You can call it this way from android:
public void getUser() {
// if you put a json object to the server
// the properties are automagically mapped to the methods' input parameters
JSONObject param = new JSONObject();
param.put("name", "John Doe");
param.put("age", 47);
JSONObject result = sendJsonRequest("server", 80,
"http://server:80/service1.asmx/GetUser", param);
if (result != null) {
JSONObject user = new JSONObject(result.getString("d"));
// .net webservices always return the result
// wrapped in a parameter named "d"
system.out.println(user.getString("name"));
system.out.println(user.getInt("age").toString());
}
}
Handling server exceptions on the client side:
Add this class to your project:
import org.json.JSONException;
import org.json.JSONObject;
public class JSONExceptionHelper {
private static final String KEY_MESSAGE = "Message";
private static final String KEY_EXCEPTIONTYPE = "ExceptionType";
private static final String KEY_STACKTRACE = "StackTrace";
public static boolean isException(JSONObject json) {
return json == null
? false
: json.has(KEY_MESSAGE) &&
json.has(KEY_EXCEPTIONTYPE) &&
json.has(KEY_STACKTRACE);
}
public static void ThrowJsonException(JSONObject json) throws JSONException {
String message = json.getString(KEY_MESSAGE);
String exceptiontype = json.getString(KEY_EXCEPTIONTYPE);
String stacktrace = json.getString(KEY_STACKTRACE);
StringBuilder sb = new StringBuilder();
sb.append(exceptiontype);
sb.append(": ");
sb.append(message);
sb.append(System.getProperty("line.separator"));
sb.append(stacktrace);
throw new JSONException(sb.toString());
}
}
Now replace the return statement from the sendJSONRequest with:
JSONObject json = result != null ? new JSONObject(result) : null
if (JSONExceptionHelper.isException(json))
JSONExceptionHelper.ThrowJsonException(json);
return json;
Please note: The exception is passed to the client only if connection comes from localhost.
Otherwise you get an http error 500 (or 501? I can't remember). You have to configure your IIS to send error 500 to the client.
Try it out and create a webservice that always throws an exception.

Sounds like a job for Web Services.
Start by creating a Web Service on the Windows web server, you can do this with ASP.NET (or maybe this might be more current).
On the Java side you can call the webservice and use the results that you get back. I think this question may help you get started on this side.

In case you have trouble writing web methods which return array of objects, you may want to refer here:
ksoap android web-service tutorial
Hope it helps.
