Just wondering if there is any method which would get XmlDocument from ZipFile.

\r\n

I need to build a TreeView by recursing through a ZipFile.

\r\n

Thanks

Thanks Cheeso. Sorry i misphrased my question.

\r\n

I was wondering if there is something like ZipFile.ToXml() which would return me an xmlDocument of ZipFile contents.

\r\n

Thanks.

I don't know what ZipFile.ToXml() would do, but, I'm sure you could build one yourself just iterating through the list of entries.

I tried but i failed. I agree am not that good. I just need the filenames in zipfile as xmlDocument from which i would like to build a treeview.

\r\n

Thanks

There's an example that populates a treeview from a zipfile, in the source download.

I converted it to C# but it is not giving the result expected:

\r\n

Down below in vb.net default(TreeNodeCollection) is used and i have set it to null.

\r\n

Not sure if that is right.

\r\n

Please advise.

Are you using Visual Studio?  there's a green squiggly on the test in FindNodeForTag :

\"\"

If you cast to a string, you will get the results you want, I think.
