Find a file with a certain extension in folder
Look at the System.IO.Directory class and the static method GetFiles. It has an overload that accepts a path and a search pattern. Example: string[] files = System.IO.Directory.GetFiles(path, “*.txt”);

Is there a way of making strings file-path safe in c#?
Ugh, I hate it when people try to guess at which characters are valid. Besides being completely non-portable (always thinking about Mono), both of the earlier comments missed more 25 invalid characters. foreach (var c in Path.GetInvalidFileNameChars()) { fileName = fileName.Replace(c, ‘-‘); } Or in VB: ‘Clean just a filename Dim filename As String = … Read more
Why use os.path.join over string concatenation?
Portable Write filepath manipulations once and it works across many different platforms, for free. The delimiting character is abstracted away, making your job easier. Smart You no longer need to worry if that directory path had a trailing slash or not. os.path.join will add it if it needs to. Clear Using os.path.join makes it obvious … Read more
Getting current directory in .NET web application
The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website. You want HttpRuntime.AppDomainAppPath. If you’re in an HTTP request, you can also call Server.MapPath(“~/Whatever”).
Check whether a path is valid in Python without creating a file at the path’s target
tl;dr Call the is_path_exists_or_creatable() function defined below. Strictly Python 3. That’s just how we roll. A Tale of Two Questions The question of “How do I test pathname validity and, for valid pathnames, the existence or writability of those paths?” is clearly two separate questions. Both are interesting, and neither have received a genuinely satisfactory … Read more
mkdir if not exists using golang
Okay I figured it out thanks to this question/answer import( “os” “path/filepath” ) newpath := filepath.Join(“.”, “public”) err := os.MkdirAll(newpath, os.ModePerm) // TODO: handle error Relevant Go doc for MkdirAll: MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. … If path is already a … Read more
How to get URI from an asset File?
There is no “absolute path for a file existing in the asset folder”. The content of your project’s assets/ folder are packaged in the APK file. Use an AssetManager object to get an InputStream on an asset. For WebView, you can use the file Uri scheme in much the same way you would use a … Read more
Command copy exited with code 4 when building – Visual Studio restart solves it
While /C may ignore errors, it might not be the real solution as there could be files that MUST be copied in order for the build to be successful. The most common issue is the missing quotes around the pre-defined command tags (such as $TargetDir). When one creates various branches and paths in code or … Read more
Difference between forward slash (/) and backslash (\) in file path
/ is the path separator on Unix and Unix-like systems. Modern Windows can generally use both \ and / interchangeably for filepaths, but Microsoft has advocated for the use of \ as the path separator for decades. This is done for historical reasons that date as far back as the 1970s, predating Windows by over … Read more
Get the (last part of) current directory name in C#
You could try: var path = @”/Users/smcho/filegen_from_directory/AIRPassthrough/”; var dirName = new DirectoryInfo(path).Name;
