IQueryable Linq To SQL With Multiple Operators

Public Function GetRegions() As IQueryable(Of Region) Implements IRegionRepository.GetRegions
Dim region = (From r In dc.Regions
Select r)
Return region.AsQueryable
End Function
Now in my Service layer I've got a function like this

ADO.NET :: Dynamically Adding MyColumn LIKE '%@MyParameter%' To The Linq IQueryable Object
Jan 11, 2011My situation is as follows:
I do some filtering on the IQueryable<MyType> object using the Contains() function in Linq, which in effect adds: MyColumn LIKE '%@MyParameter%' to the linq requestI want to make the function more generic, which could operate on a IQueryable object of an unknown type. In such case I do not know the type yet, therefore I can not add a standard .Contains() function. All I have present are the IQueryable object, the MyColumn and MyParameter as a string text. I need to be able to add "MyColumn LIKE '%@MyParameter%'" to the Linq object, dynamically ...
How can I write a piece of code that would run the Contains() on the IQueryable, knowing the Column name (as string) and the parameter value (as a string too) - I basically want to add this: MyColumn LIKE '%@MyParameter%' to the Linq where clause.
I have found something doing the .Where() function dynamically, but I do not entirely understand what is happening in there, so I struggle to convert it to Contains():
[Code]....

WCF / ASMX :: Web Service - Convert Datatable To XML

The problem is 'Null' values in the datatable don't show up as empty tags in the XML so when I read the XML from the web service this is no consistency. Is there a way to show the tags even when the fields are null in the datatable or is there a better way to accomplish what I need. I'm reading this web service from a silverlight application with the following code (this application works but, it doesn't show all the employees as it skips over when no tag is present):

Jul 11, 2011I have a datatable that I need to convert into a javascript array. This will allow me to do client-side validations on my webpage.
My datatable has 6 columns. X rows depending of the query results.
I was looking to use Me.ClientScript.RegisterArrayDeclaration but I just can't find how to build my 2-dimentional array to feed to this declaration.

ADO.NET :: How To Filter DataTable Using LINQ
Feb 10, 2011Many times I need to manipulate with DataTable after I get data from database using adapter.Fill(table).
Usually I calculate data in DataTable by using loops. But I know that there is simpler way using LINQ. I know some basics about that just for strongly typed objects.I can't find how to do this with DataTable that is not strongly typed. How could I get all DataRow or Filtered DataTable (not just value for the field) from table for that conditions:
- where the specified field of the table contans MAX/MIN/AVG value,
- where the specified field of the table equals to some value.
