I want to convert a Guid to a UUID or a string version of the same so that the following CQL query will work. 

```
                        if (cassandraDb.ExecuteQuery(string.Format("SELECT OrderGroupId FROM Order WHERE OrderGroupId={0}", orderGroupId)).Count() <= 0)                            {

```

The variable 'orderGroupId' is a Guid. Obviously this is using FluentCassandra in a C#/.NET environmnet. Any hints?

Thank you.
