Using ADO.NET Data Collections (DataSet)

ADO.NET DataTable can also be used in LiveLinq, for example:

C#
Copy Code 
CustomersDataTable customers = ...
var query =
  from c in customers.AsIndexed() where c.City == "London" select c;
For that, you’ll need to add
C#
Copy Code 
using C1.LiveLinq.AdoNet;

to your source file. The AsIndexed() used will be  C1.LiveLinq.AdoNet.AdoNetExtensions.AsIndexed. It is specifically optimized for data in ADO.NET DataSets.
