GetCustomAttributes On An Anonymous Delegate?
Dec 14, 2010I am struggling to retrieve custom attributes from a method. As you can see, the method ProcessXML has a custom attribute. The method itself gets passed into an anonymous delegate and then, in that context, I'm looking to get its custom attributes, but I'm not sure quite how to do it.
Here's my code
Public Sub UpdateXML()
Dim errors = New Errors
Dim xml = <testxml>

Multicast Delegate: Represents A Multicast Delegate; That Is, A Delegate That Can Have More Than One Element In Its Invocation List?
Jan 30, 2010from the documentation we have this: Multicast Delegate: Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.
so am i right to say that Multicast delegate is no different from a normal delegate other than the fact that it has arguments. so System.Action is a 'normal' delegate whereas System.Action(T)(Byval obj as T) is a multicast delegate?

Multithreading - Delegate Within A Delegate?
Mar 23, 2010I am trying to write a VB.NET alternative to a C# anonymous function.I wish to call Threading.SynchronizationContext.Current.Send which expects a delegate of type Threading.SendOrPostCallback to be passed to it. The background is here, but because I wish to both pass in a string to MessageBox.Show and also capture the DialogResult I need to define another delegate within. I am struggling with the VB.NET syntax, both from the traditional delegate style, and lambda functions.My go at the traditional syntax is below, but I have gut feeling it should be much simpler than this:
Private Sub CollectMesssageBoxResultFromUserAsDelegate(ByVal messageToShow As String, ByRef wasCanceled As Boolean)
wasCanceled = False

.net - Anonymous Functions In C#?
Mar 13, 2011The following syntax is valid VB.NET code
Dim myCollection As New List(Of Stock)
myCollection.Add(New Stock(Guid.NewGuid, "Item1"))

[code]....
How can I accomplish the same thing in C#? I have tried...
myCollection.FindAll(bool delegate(Stock stock) {
if (blah blah) {
}
});
But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

.net LINQ Xml Query - Anonymous Type?
Oct 22, 2009I'm out of my depth populating a windows form from an XML linq query (see code further down in post). The listbox is populated as intended, when a value is selected (row) I would like to populate the remaining form controls. The linq query I believe has created a new datatype "Anonymous Types". The query is only local to the load form subroutine but I'm not sure how to make it global.
When I define the query simply as an object the code in the selectedValueChanged event can't execute due to late databinding. how I can initially load the listbox from linq xml query and then populate the other controls when the value changes? Am I right in thinking even though the listbox is multi-columns (property) you can ONLY ever reference a row and NOT a column? I'm new to LINQ and Anonymous Types and the more I read the more confused I seem to get. On a less important note the order by is not functioning as intended (no errors) but data is always retrieved in xml file order and not by the node <text>. Also looked at using <text>.first to order the results without success.
