SYSK 47: OLEDB deja vu? A look into LINQ.
Remember the promise of OLEDB? Regardless of where the data is stored – relational database, exchange, text file, etc – OLEDB can retrieve it using familiar, SQL like syntax…
Well, LINQ is the new technology that can query into any type of data – objects, relational data, xml – using SQL like syntax.
For example:
string[] names = { "Burke", "Connor", "Frank",
"Everett", "Albert", "George",
"Harris", "David" };
IEnumerable<string> expr = from s in names
where s.Length == 5
orderby s
select s.ToUpper();
Care to guess the result? The answer is at this URL: http://msdn.microsoft.com/netframework/future/linq/default.aspx?pull=/library/en-us/dndotnet/html/linqprojectovw.asp.
