C# - Serializing Data From A RSS Feed?
May 20, 2010
I'd like the user to specify a RSS feed address and serialize the information from it. I am not interested in the XML format, but populate a strongly typed object from the XML. My question is, is there a standard that all RSS feeds support (Do all of them have date, title etc)? If so, is there a XSD that describes this.If not, how do I handle serializing a RSS feed to an object in ASP.NET?
EDIT:
The SyndicationFeed's Items have the following properties:
Title.Text -> Gives us the title
Summary.Text -> Gives the Summary
Q1 - The Summary includes the html tags. Is there a way to strip them? I am interested only in the text
Q2 - Do all RSS feeds have full content in the Summary element? I see that some RSS feeds have only a few lines for Summary while others have the entire content of the post.

I've wanted to incorporate my blog into my website, and be able to organize the data in the blog based on the keyword tags- so I can use the single blog and present relevant blog entries on different sections of my website, where I have control over the formatting, etc.
After exhaustive research (where I've learned a lot about RSS, XML, ATOM), it looks like I'm going to have to write one heck of an extensive xsl file to be able to access the XML data in an atom feed, and it seems that surely I am trying to reinvent the wheel.
Does Visual Web Developer Express have a better way to create a website with atom feed elements? If not, is there another way I should go about this?

I am going to import some data, and I have the data available in either a JSON feed or a XML feed. I can't decide if I should use the XML or the JSON feed.
What are the pros and cons of choosing either feed, and what is your prefered choice?

I am required to create a functionality like the "Top Tweets" of www.twitter.com,I started out thinking that it would be simple and just use a update panel and a timer with a gridview in the middle of it and just have it update every few seconds. but as you can see the problem here it updates the whole entire gridview and I just want to go ahead and add the new updates to the top of the page and not refresh the whole entire feed everyfew seconds.

I have an object called MyObject that has several properties. MyList is a list of MyObject that I populate with a linq query and then I serialize MyList into json. I end up with something like this
List<MyObject> MyList = new List<MyObject>();
MyList = TheLinqQuery(TheParam);
var TheJson = new System.Web.Script.Serialization.JavaScriptSerializer();
string MyJson = TheJson.Serialize(MyList);
What I want to do is serialize only parts of MyObject. For instance, I might have Property1, Property2...Propertyn and I want MyJson to only include Property3, Property5 and Property8.
I thought of a way to do this by creating a new object with only the properties I want and from there create a new list for the serialization.

I have an ASMX web service that returns a large dataset. The objects are custom. That is, I am not sending DataSets or other complex objects. I need to chunk the response because it could be large. Following this: http://support.microsoft.com/kb/278998, I have enabled chunked transfer encoding on the server. The client is java. I am doing something along these lines:
connection.setRequestProperty("Range", "bytes=" + rangeStart + "-" + rangeEnd);
int responseCode = connection.getResponseCode();
I see the request property come in on the server side. I see the server build the response. I am tracing the outbound soap, and it appears to be created. I expected to get a response code of 206 back when the response is large. But, I always get 200 (or an error if the request is too large, Request Entity too large on the BlackBerry).What do I need to do on the server side to chunk? I can explore moving to WCF if I have to, but, would rather avoid it. I am guessing I need to implement the chunking while serializing or possibly write a custom HTTP Handler to do it for me. The problem with the serializer approach is, the web service framework is doing the serilization for me. I can take this approach if needed.

I have the following code:
<script type="text/javascript">
var checksSinceLastPostBack = new Array();
function clientSelectedIndexChanged(sender, eventArgs) {
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
var serializedCheckData = checksSinceLastPostBack.serializeArray();
if (ajaxManager != null)
ajaxManager.ajaxRequest(serializedCheckData);
}
</script>
The
var serializedCheckData = checksSinceLastPostBack.serializeArray();
doesn't seem to work. Am I misunderstanding this?
Also if this works, how would I deserialize it in the code behind?

i need to pass my Request.Form as a parameter, but first i have to add some key/value pairs to it. I get the exception that the Collection is readonly.
I've tried:
System.Collections.Specialized.NameValueCollection myform = Request.Form;
and i get the same error.
and i've tried:
foreach(KeyValuePair<string, string> pair in Request.Form)
{
Response.Write(Convert.ToString(pair.Key) + " - " + Convert.ToString(pair.Value) + "<br />");
}
to test if i can pass it one by one to another dictionary, but i get:
System.InvalidCastException: Specified cast is not valid.

I am getting an error when trying to serialize an object products.
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[3,2] { {"Small","40"}, {"Medium","44"}, {"Large","50"} };
string json = JsonConvert.SerializeObject(product);//this line is throwing an error
Array was not a one-dimensional array. Is there any way to serialize a two dimensional array with Newtonsoft.json.

I have a WCF service that when the objects serialize to clients an extra property is getting added with a 'Speficied' suffix. At first I thought it had to to with a couple of nullable type properties, but it is happening to all of my value types even if it is not declared Nullable. How can I get rid of this?

Is it possible to serialize object direct from Visual Studio .NET Debug window. I have a very complex object structure which contains multiple sub objects along with List item etc. I mean the Hierarchy is complex. And I need to analyze the object graph closely for that I need an offline view (may be in the from of XML/ Serialization). I can not do that from VS.
(One can reccomend me to use XMLSeriliazation in my code to generate but please consider that may not be alwways possible because of
1. with default .NET Serialization class a complex object which has manu sub objcts with Collection. is not get serialized properly. So need custom serialization & deserilazation code for that, does not come witf Microsoft Librarry.)
2. I am using it somewhere (Silverlift app) where such operation may be not possible.
3. I do not want to spent time creating or evaluating any ones custom serilaization code/tool

I have an Entity Framework data model. Part of the model is a Customer entity. The web service provides a method to get a customer, and to receive an updated version of this customer to be persisted.
To test this, I created a new ASP.NET web Application, (Solution > Add > New Project > ASP.NET Web Application), then added a reference to my service reference using the standard Add Service Reference dialog. I then call the service using the following code:
var client = new CustomerServiceClient();
var customer = client.GetCustomerByID(18); // get it
customer.LimitDown = 100; // change it
client.SaveCustomer(customer); // persist it
Everything works as expected.
Now, I do exactly the same thing, but this time with as ASP.NET Web Site (Solution > Add > New Web Site > ASP.NET Web Site). I add the reference in a similar fashion and copy and paste the code above into the new site. But now I get the following exception thrown on the 4th line:
System.InvalidOperationException The EntityReference object could not be serialized. This type of object cannot be serialized when t RelationshipManager belongs to an entity object that does not implement IEntityWithRelationships.
Source Error:
Line 2474: Line 2475:
public
SkyWalkerCustomerService.OperationResult
SaveCustomer(SkyWalkerCustomerService.Customer[code]....
Googling for this error returns very little. Why doesn't this work?I guess one answer would be to use a web application instead of a web site, but I have an large existing site to which I need to add the service reference, and I'd rather not convert it.

I have a system that has several large objects that need to be built and populated each and every time, and these objects may be accessed quite often as well. As a strategy, caching would not be that good for me because there are potentially thousands of these objects which are fairly large. So I propose to serialize the objects to the file system and then deserialize it when I need those objects again. I have several classes that need this serialization functionality.
These objects change as well, so on the next access I check if there were any changes and then I grab only the changes and edit the object, and then reserialize the object.
My question is what is the best way to do this, since I have several classes ..
