oneEntry.WriteToDirectory(@"D:\result", extractionOptions);
}
throw System.NotImplementedException:“The method or operation is not implemented.”
but the file is really uncompress success.I think is BUG

Also I found any rar file use WriteToFile is same (throw System.NotImplementedException:“The method or operation is not implemented.”but the file is really uncompress success)

if you have the test file available we can have a look on why it gives not implemented. RAR support is not complete but mostly works.
@zhangqi-ulua commented on GitHub (Jan 5, 2024):
The reason I didn't upload a RAR attachment earlier is that for any RAR file, attempting to execute WriteToDirectory or WriteToFile on any of the entries throws a NotImplementedException, even though the files can be extracted normally. If you really need me to upload one, I can upload just any file（Since GitHub does not support uploading files in RAR format, I have placed the RAR test file inside a ZIP file for uploading.
test.zip
）.
Additionally, I've encountered another issue. For any 7z file that contains a large number of files, a full extraction of the 7z file might take around 10 seconds, but if I use a foreach loop to execute WriteToFile for each entry, the total time taken is more than tenfold.
@Erior commented on GitHub (Jan 5, 2024):
The ExtractOptions above should work with the pull request I made.
I can add that NTFS ACL and UNIX owner handling is not implemented for RAR files, but does not trigger an exception
