Techie Blog 6/10 Geek Factor

It's the morning of my second day at the PDC and my body finally caved in last night and decided that it did need some sleep. Well until 3am at least. Still It did give me the pportunity to have a read of the Linq project white paper.

Basically this is a new integrated query language that you can use within your .Net code. It will be in c|

sharp ver 3 and VB 9. This new feature will is called .NET language integrated query (LINQ). It will provide a standard set of operators to work with data wether it be XML(XLINQ) or SQL(DLINQ). It provides strong typing over relational data while retaining the relation nature of the SQL language.

The syntax is slightly different in VB than Csharp but more to do with the order of the operators (VB appears structured more closely to Transact SQL as I know it)

Imagine we have an array of string values valled nameList we could in .Net code write:

IEnumerable<string> vals = from s in nameList

where s.Length == 4

orderby s

select s.ToUpper();

Then we could do a foreach loop over vals to return a list of values that are 4 characters long ordered and upper case.

There is more to this which I may cover later if I get a chance to do some hands on labs but for more info goto.
