Consider the following C# code:

However, I'd like to be able to implement a method like SomeMethod from the C# example in VB.net. Likely this means wrapping the Backgroundworker in another class (which is something I want to do for dependency injection and unit testing anyway).
Is it possible to shorten the following function to a lambda expression?Or (to do the trick by myself) what is the best and most understandable for beginners tutorial for lambda in vb.net?[code]
View 2 RepliesI have the following code which assigns values to a datarow and and adds to the datatable. I want to write function which returns a datarow which enables me to write less code.

I have this function that maps a IDataReader to a class. It is obviously written in C#. My co-worker wants to use the same method in his code, but he is writing in VB.net. Basically I am having difficulty rewriting this due to the Lambda expressions used in C#. He is running .Net 3.5.

Should I be concerned about the performance of the Compile method here?[code]...
The reason I want the lambda expression is because I want that function to be able to get all the way through LINQ-to-SQL to be converted to SQL. The reason I want the direct version is because I have other code that I want to validate individual serial numbers before submitting changes. And I fear that GetValidSerialNumbers.Contains(serialNumber) will execute a more-complex-than-necesssary query.
I'm trying to sort a list of string, which (each item) consists of a word followed by a space, then a number. I want to sort first alphabetically by the word, then numerically by the number. I tried something like this:
wordList = wordList.OrderBy(Function(x, y) CStr(x.Split(" "c)(0)).CompareTo(CStr(y.Split(" "c)(0)))).ThenBy(CInt(x.Split(" "c)(1)).CompareTo(CInt(y.Split(" "c)(1))))
I am trying to pass a lambda function to Linq's orderby and cannot get it to work.

I'm trying to create a generic function to build a Linq expression from a list of Telerik grid filters. I'm trying to stay clear of dynamic Linq. Because I don't know the type that I'm building the expression for, I'm attempting to use reflection in the lambda functions to refer to a property, but after applying the fix suggested by @JaredPar I get the error, "The LINQ expression node type 'Invoke' is not supported in LINQ to Entities." Is there any way around this? here is my code:
Public Shared Function buildRadFilter(Of T)(ByVal filterExpression As List(Of GridFilterExpression)) As Expressions.Expression(Of Func(Of T, Boolean))
Dim returnPred = PredicateBuilder.True(Of T)()

I'm having a problem using XML literals with a StringBuilder in VB 2008. If I use this code everything is fine.Dim html As New System.Text.StringBuilder
html.Append(<html><body></body></html>)
MsgBox("hello")
Now the problem is I want to wrap HTML around something that is generated in code.
html.Append(<html><body>)
msgbox("nothing happens")
When the HTML doesn't have the corresponding ending tag, it acts like it goes beyond the ) and keeps looking for it.
