Help with UUID in C#.net

[Sandeep]

Hi all,

I am new to Cassandra. I am trying to insert some values to the columnfamily. 
The definition of columnfamily in the config file is as follows.

<ColumnFamily Name="CommandQueue"
                    ColumnType="Super"
                    CompareWith="TimeUUIDType"
                    CompareSubcolumnsWith="UTF8Type"/>


When ever I try to insert values to I always get   
"InvalidRequestException(why: UUIDs must be exactly 16 bytes)".

I am using batch_mutate() to insert column.

How can I insert values to the column family.

Thanks,
Sandeep.
