Answer 1

I've wrapped Darin's answer into a nicely reusable extension method.

public static class UriExtensions
{
    /// 

    /// Adds the specified parameter to the Query String.
    /// 
    /// 
    /// Name of the parameter to add.
    /// Value for the parameter to add.
    /// Url with added parameter.
    public static Uri AddParameter(this Uri url, string paramName, string paramValue)
    {
        var uriBuilder = new UriBuilder(url);
        var query = HttpUtility.ParseQueryString(uriBuilder.Query);
        query[paramName] = paramValue;
        uriBuilder.Query = query.ToString();

        return uriBuilder.Uri;
    }
}

I hope this helps!
