Duplicate of : LINQ to SQL in and not in

select * from table where fieldname in ('val1', 'val2') 

or

select * from table where fieldname not in (1, 2) 

The equivalent of IN and NOT IN queries in LINQ to SQL would be something like this:

List validValues = new List() { "val1", "val2"}; 
var qry = from item in dataContext.TableName 
          where validValues.Contains(item.FieldName) 
          select item; 

and this:

List validValues = new List() { 1, 2}; 
var qry = from item in dataContext.TableName 
          where !validValues.Contains(item.FieldName) 
          select item;
