SearchOption Enumeration
.NET Framework (current version)
Specifies whether to search the current directory, or the current directory and all subdirectories.
Assembly: mscorlib (in mscorlib.dll)
| Member name | Description | |
|---|---|---|
| AllDirectories | Includes the current directory and all its subdirectories in a search operation. This option includes reparse points such as mounted drives and symbolic links in the search. | |
| TopDirectoryOnly | Includes only the current directory in a search operation. |
If you choose AllDirectories in your search and the directory structure contains a link that creates a loop, the search operation enters an infinite loop.
The following example lists all the directories and files that begin with the letter "c", as in "c:\". In this example, the SearchOption is used to specify that only the top-level directory should be searched.
using namespace System; using namespace System::IO; ref class App { public: static void Main() { // Specify the directory you want to manipulate. String^ path = "c:\\"; String^ searchPattern = "c*"; DirectoryInfo^ di = gcnew DirectoryInfo(path); array<DirectoryInfo^>^ directories = di->GetDirectories(searchPattern, SearchOption::TopDirectoryOnly); array<FileInfo^>^ files = di->GetFiles(searchPattern, SearchOption::TopDirectoryOnly); Console::WriteLine( "Directories that begin with the letter \"c\" in {0}", path); for each (DirectoryInfo^ dir in directories) { Console::WriteLine( "{0,-25} {1,25}", dir->FullName, dir->LastWriteTime); } Console::WriteLine(); Console::WriteLine( "Files that begin with the letter \"c\" in {0}", path); for each (FileInfo^ file in files) { Console::WriteLine( "{0,-25} {1,25}", file->Name, file->LastWriteTime); } } // Main() }; // App() int main() { App::Main(); }
