Application Settings + DirectoryInfo/FileInfo

阅读更多关于 Application Settings + DirectoryInfo/FileInfo

问题 I'm still new to C#... I'm building a WPF application and I'm trying to apply some User Application Settings. It's easy to insert standard App Settings (int, double, string, etc). I've even got something like WindowState inserted. I'd like to have a DirectoryInfo and/or FileInfo as savable settings instead of Strings.

Please note that this could be different from the person who created the file. Thanks Nishant 回答1: The identity of the user modifying a file is not stored in

阅读更多关于 fileinfo and mime types I've never heard of

问题 I'm not a stranger to mime types but this is strange. Normally, a text file would have been considered to be of text/plain mime but now, after implementing fileinfo, this type of file is now considered to be "text/x-pascal". I'm a little concerned because I need to be sure that I get the correct mime types set before allowing users to upload with it. Is there a cheat sheet that will give me all of the "common" mimes as they are interpreted by fileinfo? Sinan provided a link that lists all of

Does FileInfo.Extension return the last . pattern, or something else?

阅读更多关于 Does FileInfo.Extension return the last *.* pattern, or something else?

问题 I'm curious what exactly the behavior is on the following: FileInfo info = new FileInfo("C:/testfile.txt.gz"); string ext = info.Extension; Will this return ".txt.gz" or ".gz"? What is the behavior with even more extensions, such as ".txt.gz.zip" or something like that? EDIT: To be clear, I've already tested this. I would like an explanation of the property. 回答1: It will return .gz, but the explanation from MSDN (FileSystemInfo.Extension Property) isn't clear why: " The Extension property

SPLFileInfo: get filename without extension

问题 I'm accessing a number of files in the SPLFileInfo object. I see a way to get the path, filename, and even extension of the file. Is there a way to get the filename without extension?
