Ok you have had your own share of answer about linq.

Let me introduce a different approach using Dynamic.linq

// You could build a Where string that can be converted to linq.
// and do if sats and append your where sats string. as the example below
var query = "c => (c.Field1 == \" a \" && c.Field2 == Y) || (c.Field3 == \" b \")";
var indicator = query.Split('.').First(); // the indicator eg c
   // assume TABLE is the name of the class
var p = Expression.Parameter(typeof(TABLE), indicator);
var e = DynamicExpression.ParseLambda(new[] { p }, null, query);

// and simple execute the expression 
var items = Object.Where(e);
