title: C# Linq Guid Anonymous Type Problem
body: <p>I have a linq query which returns the ID of a question based on the questions text.
  This ID is then needed to be used to relate a date in a date table to that particular question. The question is already stored and the date is stored at a different time.</p>
  
  <p>The problem is that the query returns the questionID as an anonymous type and so when I need to assign that questionID as the questionID in another table, it throws an error, stating that the table is expecting a Guid. Following this, I converted the anonymous type to a string and then used the GUIDs convert feature to convert the string to a GUID, however it is now giving me the error that a GUID should be 32 characters and 4 dashes.</p>
  
  <p>My thoughts regarding this are that the anonymous type is returning the questionID as "QuestionID = jkj939-89239829- etc etc." - With the prefix of characters at the front, and thus when converting it to a GUID, the converted string contains these characters.</p>
  
  <p>Have I missed something?
  I really can't understand why it would do this, and is there a way to remove the prefix returned by the anonymous type?
  Help would be greatly appreciated.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>public static void GetQuesID(string quesText)
      {
          ExamineDataContext dc = new ExamineDataContext();
          var matchedques = from q in dc.GetTable&lt;Question&gt;()
                              where q.QuestionText.Contains(quesText)
                              select new{
                                  q.QuestionID
                              };
          foreach (var element in matchedques)
          {
              MessageBox.Show(element.ToString());
          }
  
          try
          {
              Guid g = Guid.NewGuid();
              Table&lt;DateLastUsed&gt; dlused = Repository.GetDateLastUsedTable();
              DateLastUsed dlu = new DateLastUsed(); ;
              string qidGuidString = matchedques.ToString();
              Guid convQuesGuid = new Guid(qidGuidString);
              dlu.DLUID = g;
              dlu.QuestionID = convQuesGuid;
              dlu.DateLastUsed1 = DateTime.Now;
  
              dlused.InsertOnSubmit(dlu);
              dlused.Context.SubmitChanges();
          }
          catch (Exception ex)
          {
              throw ex;
          }
      }
