How can I dynamically get parameters in the URL?

Question

My problem is, that i want to build my webpage dynamically. I get all the Inforamtions from my database but I can't pass for an example the ID to an other page to build the new Page. What i have so far:

MySqlDataReader r = command.ExecuteReader();
<a id="@r["ID"]" href="test.cshtml?id="+@r["ID"]  title="test" method="get" 
name="id">test</a>

The URL should look like: ~/test.cshtml?id=1

When I want to request the parameter with:

int message = Convert.ToInt32(Request.QueryString["id"]);

I don't receive anything from my previous page. The problem is that the URL is still ~/test.cshtml .

Answer 1

I found a solution:

string QueryString = "test.cshtml?id=" + r["ID"].ToString(); 
<a id="@r["ID"]" href=@QueryString title="Detail" method="get" name="id">Details</a> 

The problem was I tried to concatenate 2 string in an a tag, but that is not possible. So i tried to concatenate these 2 before and it works
