Generic methods that return anonymous types [duplicate]

This question already has an answer here:

• Return Anonymous Type from a function 5 answers

I have been googling this question for a while. With that said, it seems that I keep getting the same answer, not the answer I am looking for. So I thought I would ask here. What I would like to do is create an anonymousType and pass it in to a method for that method to use like a strongly typed class.

How can I do this?

            var desiredAnonymousTypes = new
        {
            Column1Name = ColumnTypeHere,
            Column2Name = ColumnTypeHere,
            Column3Name = ColumnTypeHere
        };

        SqlParameter[] @params =
        {
            new SqlParameter("UserName","Jon Doe")
        };

        var list = CastExample.RunStoredProcdure<desiredAnonymousTypes>("GetContactsByUser", @params);

    public static IEnumerable<T> RunStoredProcdure<T>(string sprocName, SqlParameter[] @prams)
    {
        var list = new List<T>();

        //run sproc already works

        return list;
    }
