Sharepoint list Dynamic Linq query

Question

I need to query a list in SharePoint where the columns may be added in the future. For instance at the moment I have the following columns Name, Job, interests, address I want to be able to query this string dynamically using a parameter from the browser so if columns are added in the future I don’t have to change the code but just the parameter. The address may look like this www.contoso.com/sites/mypage.aspx?property=Interests And the code something on the line of this:

var SiteParameter = Request.QueryString["property"];

var ItemsFromList = from item in ListItems where item[try to put the parameter in here] select item;

I use SPmetal to get the list details, so if I press item. Visual Studio2010 will return the columns within the list.

Answer 1

This may be easier without SPMetal.

var qy = new SPQuery();
qy.Query =
    "<Where><Eq>" +
        "<FieldRef Name=`" + siteParameter + "'/>" +
        // You may have to worry about the type of the field here, too.
        "<Value Type='Text'>" + desiredValue + "</Value>" + 
    "</Eq></Where>";
var itemCollection = myList.GetItems(qy);
