ADO.NET :: Dynamically Adding MyColumn LIKE '%@MyParameter%' To The Linq IQueryable Object

My 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]....

adding dynamic .Contains() to the IQueryable object only using the string column name and the string value
