I'm curious what everyone does for handling/abstracting the QueryString in ASP.NET. In some of our web apps I see a lot of this all over the site:
int val = 0;
if(Request.QueryString["someKey"] != null)
{
val = Convert.ToInt32(Request.QueryString["someKey"]);
}
What are some better ways to handle this grossness?
We've been using constants to keep all of these "loose" keys in a central location:
public class Constants
{
public class QueryString
{
public const string PostID = "pid";
public const string PostKey = "key";
}
public class Cookie
{
public const string UserID = "mydomain.com-userid";
}
public class Cache
{
public const string PagedPostList = "PagedPostList-{0}-{1}";
}
public class Context
{
public const string PostID = "PostID";
}
public class Security
{
public const RoleAdministrator = "Administrator";
}
}
That way, you easily access the constants you need with:
public void Index()
{
if (Request[Constants.QueryString.PostKey] == "eduncan911")
{
// do something
}
}
public object GetPostsFromCache(int postID, int userID)
{
String cacheKey = String.Format(
Constants.Cache.PagedPostList
, userID
, postID);
return Cache[cacheKey] as IList<Post>;
}
