ASP.NET cannot parse xml! Check file path

Question

I created a simple API through ASP.NET MVC 4:

public class ActionController : ApiController
{
    [WebMethod]
    public string getCommunities()
    {
        try
        {
            MethodClass method = new MethodClass();
            return method.getCommunities();
        }
        catch(Exception ex)
        {
            return ex.Message.ToString();
        }
    }
}

which is trying to call this method in the Method class:

public string getCommunities()
{
    return "bbb";
}

but for some reason I get this error:

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">cannot parse xml! Check file path</string>

I tried Googling for an error, but didn't come up with anything, has anyone seen this error before? and how to fix it?

Answer 1

As already mentioned in the comments, you are looking for an error in the wrong place. method.getCommunities () throws an error with the message "cannot parse xml! Check file path".

Google , : .

API, -API Visual Studio.

public string Get(int id)
        {
            try
            {
                var t = 0;
                var i = 1 / t;
                return "bbb";
            }
            catch { return "ABBA"; }
        }

xml

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">ABBA</string>

in Global.asax.cs you should add the code below:

GlobalConfiguration.Configuration.Formatters.Clear (); GlobalConfiguration.Configuration.Formatters.Add (new System.Net.Http.Formatting.XmlMediaTypeFormatter ());

and in the text below of WebApiConfig:

config.Formatters.XmlFormatter.SupportedMediaTypes.Add (new MediaTypeHeaderValue ("text / xml")); var appXmlType = config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault (t => t.MediaType == "application / xml");
