How to parse a delegate method from a xml file?
I would like to be able to have a button for my interface that uses different delegates if pressed etc.
And in order to make it easy it would be 开发者_StackOverflownice to be able to load the buttons from XML. I already have it setup like this:
<EclipseButton name="button1" texkey="thumbnail" istodraw="True">
<position>
<x>10</x>
<y>10</y>
</position>
<width>64</width>
<height>64</height>
</EclipseButton>
But I would like to be able to add:
<IfPressed>
<![CDATA[
Console.WriteLine("The button is pressed");
]]>
</IfPressed>
And then I can convert the text in cdata as if it were a lambda:
() => { Console.WriteLine("The button is pressed"); }
Is there anyway to make this possible?
As an alternate to @Yahia's response, you can create a list of pre-defined actions (similar to what the ASP AJAX Control Toolkits do for actions) and allow the markup to specify order, etc. e.g.
<IfPressed>
<WriteToConsole Text="The button is pressed" />
</IfPressed>
Then parse the collection as a to-do list, going through each added item and executing it.
it is possible although not easy - see http://msdn.microsoft.com/de-de/library/650ax5cx.aspx
You would need to compile the code at runtime and use reflection to invoke etc.
