AddExtensionObject and XSLT

Today i had some frustration with passing objects to XSLT using AddExtensionObject.
Calling methods from XSLT worked, but not the properties.
I did some googling but couldn't find the answer. It seem as if XSLT doesn't support object properties. This is such a nuisance.

Update:

I found a solution! It turnes out that .NET creates getter and setter methods for each property in IL.
E.g. if you had a read/write property Address, the in the IL it'll have corresponding methods get_Address() and set_Address(string).
So you can access property from XSLT by calling "get_[PropertyName]()" method.

I having the same problem. I can't pass node attributes to a c# function in xsl.
Did you ever find a solution?

Thanks

# re: AddExtensionObject and XSLT

Hi there,

My problem is samilar. I try to pass the hashtable property, this[object key].

In C#:
private Hashtable ht = new Hashtable();
Form form = new Form();
form.type = "text";
ht.add(form); xslArg.AddExtensionObject("ext:ext", ht);

In xslt:
I tried use "get_ht['key']", returns me nothing. If I try to use "get_ht['key']()", give me an error message, says "Expected end of the expression, found '('. ...ext:get_ht['key'] -->(<-- )"

Also, how can I call a method like <xsl:value-of select="ext:get_ht[@Key].get_Type()" />, a object in the hashtable, which has a "Type" property? It will return me an error: "Expected end of the expression, found '.'. ...ext:get_ht[@Key] -->.<-- get_Type()"...

By the way, how can I use "xsl:for-each" for "get_Keys()" method? <xsl:for-each select ="ext:get_Keys()"> returns an error message as "Expression must evaluate to a node-set."

Thanks a lot
