Parse string with wiki markdown and show like in browser

Hopefully you can help me as I do not find a solution neither on the web nor in my brain.
I am querying a issue-tracking-system (jira) via a webrequest. The systems answer is a json-file with a description of an issue represented by a string that has wiki-markdowns in it. It is possible to show this string 1:1 to the user. But I would prefer a solution to somehow parse the string and show the user not the textual markdown but the parsed elements like tables or numbered enumerations.
I use C# and currently I am showing the information in a richtextbox, but I guess richtextbox is not the element you choose for such a requirement.
For Example the following string is returned by the jira-system and I would like it to be shown as a "real" table and an enumeration to the user.

Hope you can help me

after long researches the answer is totally simple.
The Jira offers a conversion from markdown to html itself. When you query an issue via a URL just add ?expand=renderedFields to the URL like explained here https://community.atlassian.com/t5/Answers-Developer-Questions/How-can-I-get-the-rendered-HTML-of-a-wiki-markup-field-in-JIRA/qaq-p/495779
You will receive the answer like before and additional to that the html-writing of the answer. With that answer it is almost simple to show it in an webbrowser-element in the UI

Include array in QueryString?

Our webform (ProcessStudent.aspx) is designed to receive three parameters in the QueryString: Name, Grade, Class. Page_Load retrieves these three parameters and sends it to a method SaveStudent (ie. SaveStudent(name, grade, class);).
I need to process several three-parameter combinations for one page. I basically copied/pasted ProcessStudent.aspx, but I need to modify the way I read the parameters. I can change the URL structure, but everything else needs to stay the same.
So my initial thought was to include these combinations in the URL; for example, each value would be separated by a char and each combination by another char. Something like this, which I would then parse :
ProcessStudent.aspx?Students=Joe|5|Science,Bob|6|Math,Mary|5|English
Would something like this work? Is there a better way?

Yes it would work. As far as better... You could post a json string, which would be much cleaner. I personally would use a rest service with just JSON(or XML if you like).
Hope this helps.

The thing you'll need to watch out for is that the query string has a length limit in some browsers (https://stackoverflow.com/a/812962/97382) so depending how many you mean by "several" and which browser(s) you're using you could run into those limitations.
You would be better off to POST the data as you do not run into the size limitations.

How display data generated by Rich Text Editor in ASP.NET MVC? [duplicate]

I have a controller which generates a string containing html markup. When it displays on views, it is displayed as a simple string containing all tags.
I tried to use an Html helper to encode/decode to display it properly, but it is not working.
string str= "seeker has applied to Job floated by you.</br>";
On my views,
#Html.Encode(str)

You are close you want to use #Html.Raw(str)
#Html.Encode takes strings and ensures that all the special characters are handled properly. These include characters like spaces.

You should be using IHtmlString instead:
IHtmlString str = new HtmlString("seeker has applied to Job floated by you.</br>");
Whenever you have model properties or variables that need to hold HTML, I feel this is generally a better practice. First of all, it is a bit cleaner. For example:
#Html.Raw(str)
Compared to:
#str
Also, I also think it's a bit safer vs. using #Html.Raw(), as the concern of whether your data is HTML is kept in your controller. In an environment where you have front-end vs. back-end developers, your back-end developers may be more in tune with what data can hold HTML values, thus keeping this concern in the back-end (controller).
I generally try to avoid using Html.Raw() whenever possible.
One other thing worth noting, is I'm not sure where you're assigning str, but a few things that concern me with how you may be implementing this.
First, this should be done in a controller, regardless of your solution (IHtmlString or Html.Raw). You should avoid any logic like this in your view, as it doesn't really belong there.
Additionally, you should be using your ViewModel for getting values to your view (and again, ideally using IHtmlString as the property type). Seeing something like #Html.Encode(str) is a little concerning, unless you were doing this just to simplify your example.

you can use
#Html.Raw(str)
See MSDN for more
Returns markup that is not HTML encoded.
This method wraps HTML markup using the IHtmlString class, which
renders unencoded HTML.

I had a similar problem with HTML input fields in MVC. The web paged only showed the first keyword of the field.
Example: input field: "The quick brown fox" Displayed value: "The"
The resolution was to put the variable in quotes in the value statement as follows:
<input class="ParmInput" type="text" id="respondingRangerUnit" name="respondingRangerUnit"
onchange="validateInteger(this.value)" value="#ViewBag.respondingRangerUnit">

I had a similar problem recently, and google landed me here, so I put this answer here in case others land here as well, for completeness.
I noticed that when I had badly formatted html, I was actually having all my html tags stripped out, with just the non-tag content remaining. I particularly had a table with a missing opening table tag, and then all my html tags from the entire string where ripped out completely.
So, if the above doesn't work, and you're still scratching your head, then also check you html for being valid.
I notice even after I got it working, MVC was adding tbody tags where I had none. This tells me there is clean up happening (MVC 5), and that when it can't happen, it strips out all/some tags.

Reading values from webpage programmatically

I don't know what it called, but i think this is possible
I am looking to write something(don't know the exact name) that will,
go to a webpage and select a value from drop-down box on that page and read values from that page after selection, I am not sure weather it called crawler or activity, i am new to this but i heard long time back from one of my friend this can be done,
can any one please give me a head start
Thanks

You need an HTTP client library (perhaps libcurl in C, or some C# wrapper for it, or some native C# HTTP client library like this).
You also need to parse the retrieved HTML content. So you probably need an HTML parsing library (maybe HTML agility pack).
If the targeted webpage is nearly fixed and has e.g. some comments to ease finding the relevant part, you might use simpler or ad-hoc parsing techniques.
Some sites might send a nearly empty static HTML client, with the actual page being dynamically constructed by Javascript scripts (Ajax). In that case, you are unlucky.
Maybe you want some web service ....

One simple way (but not the most efficient way) is to simply read the webpage as String using the WebClient, for example:
WebClient Web = new WebClient();
String Data = Web.DownloadString("Address");
Now since HTML is simply an XML document you can parse the string to a XDocument and look up the tag that represents the dropdown box. Parsing the string to XDocument is done this way:
XDocument xdoc = XDocument.Pase(Data);
Update:
If you want to read the result of the selected value, and that result is displayed within the page do this:
Get all the items as I explained.
If the page does not make use of models, then you can use your selected value as an argument for example :
www.somepage.com/Name=YourItem?
Read the page again and find the value

ASP.NET: dynamicly generating HTML, how to?

I've been doing ASP.NET a little bit (on and off) over the last year, but I've never come upon this challenge: I'm building a website right now which is quite simple, mostly based in HTML and Javascript. However, on one page, I need to read an XML file off the server, parse it, create HTML from values contained in the XML file, and output it as the response. I am going to use ASP.NET with C# for this. I understand how to parse the XML and generate the HTML code in C#, but how do I write the HTML code into the response/into the page? The generated dynamic HTML is only in one big div in the page, and the rest of the page is static. What is the best way to do this? As I've never done anything like this before, I'm guessing that one way to do it would be to clear the whole HTML source of the page and use Response.Write() in the Page_Load event to write in the whole HTML of the page, with the XML values already inserted. Is this the correct method, and if so, could you give me a few lines of code as an example to make sure that I'm doing it right? Thanks!
Also, as I've never had the opportunity to do this before, what is the best way of reading a file in ASP.NET C# that is located on your server?
UPDATE: Thank you for all the answers! I have found the solution to my problem, and yet all three answers provided are good ways of approaching this challenge. As you can guess, it's a tough choice who to give the accepted answer to, but I'm going to give it to this answer, by awe, because he clearly put a lot of effort into it, it's a quite elegant solution, and he answered both my questions. Thank you all for the wonderful answers!

Create a div that is accessible in server code:
<div runat="server" id="xmlGeneratedContent"></div>
In Page_Load:
xmlGeneratedContent.InnerHtml = parcedHtmlFromXml;
EDIT:
As answer to the last question: how to read a file on the server...
If the file is located under the web site, you can use Server.MapPath to get the physical disk location from the relative url:
string filename = Server.MapPath("files/file.txt");
How to read it depends on what kind of file it is, and how you want to read it. If you want to read it as plain text, here are some methods:
Read all at once:
string content = System.IO.File.ReadAllText(filename);
Read all at once into string array containing the lines:
string[] content = System.IO.File.ReadAllLines(filename);
Read one line at a time:
System.IO.StreamReader sr = new System.IO.StreamReader(filename);
while (!sr.EndOfStream)
{
string line = sr.ReadLine(); // or other method reading a block
//Do something whith the line
}
sr.Close();
sr.Dispose();

In codebehind function:
public string getHML()
{
return "htmltext";
}
on Page:
<div><%=getHML()%></div>

Just to add to the diversity: My favorite solution is to use
<asp:Literal runat="server" ID="myLiteral" />
And then in code:
this.MyLiteral.Text = "Generated HTML goes here";
The advantage over a <div> is that this generates no extra HTML - so you can put it wherever you want and generate whatever you want.
Often I also set EnableViewState="false" on it, if I can easily regenerate the contents on every request. This cuts down on the ViewState size, because the myLiteral.Text is also saved in ViewState.

Well, your own suggestion would certainly work. Clear out all the html in the ASPX page, and in the Page_Load event you'll do this:
Response.Write(System.IO.File.ReadAllText(yourFilePath));
I don't think there's much more to it.
