The Schema must contain a unique schema identifier. 

It sounds to me as if you are trying to reuse an existing Schema GUID:

  SchemaBuilder schemaBuilder 
    = new SchemaBuilder(
      new Guid("720080CB-DA99-40DC-9415-E53F280AA1F0"));

Every GUID must be used once only.

Dear Jeremy!!

    By changing GUID I achieved it!! 

Thank you So Much
