Especially for batch applications, the ability to deal with folders is important. This post documents the C# facilities that can give our applications the ability to work with folders.<\/p>\n

Get the folder path which the executing binary is running in<\/h3>\n
\r\nstring exeFolderPath \r\n    = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;\r\n<\/pre>\n
Check whether a folder exists<\/h3>\n
\r\n\/\/ Check if there is a folder named as techcoil in the same directory\r\n\/\/ as the running executable.\r\nif (System.IO.Directory.Exists(Path.Combine(exeFolderPath, "techcoil")))\r\n{\r\n    Console.WriteLine("Folder exists.");\r\n}\r\nelse\r\n{\r\n    Console.WriteLine("Folder does not exists.");\r\n} \/\/ end if\r\n<\/pre>\n
Create a folder<\/h3>\n
\r\n\/\/ Create a folder named as techcoil in the same folder as the \r\n\/\/ executing binary.\r\nDirectory.CreateDirectory(Path.Combine(exeFolderPath, "techcoil"));\r\n<\/pre>\n
Rename a folder<\/h3>\n
\r\n\/\/ Rename the folder from techcoil to new_techcoil\r\nDirectory.Move("techcoil", "new_techcoil");\r\n<\/pre>\n
Delete a folder<\/h3>\n
\r\n\/\/ Delete the folder named as techcoil that exists in the same folder as the \r\n\/\/ executing binary, recursively. \r\nDirectory.Delete(Path.Combine(exeFolderPath, "techcoil"), true);\r\n<\/pre>\n
Get some information about a folder<\/h3>\n
\r\nDirectoryInfo techcoilInfo = new DirectoryInfo("techcoil");\r\n\/\/ Get the time when the folder is first created\r\nConsole.WriteLine(techcoilInfo.CreationTime);\r\n\/\/ Get the full path of the directory\r\nConsole.WriteLine(techcoilInfo.FullName);\r\n\/\/ Get the last occurence when the folder is being accessed\r\nConsole.WriteLine(techcoilInfo.LastAccessTime);\r\n\/\/ Get the last occurence when the folder is written to\r\nConsole.WriteLine(techcoilInfo.LastWriteTime);\r\n\/\/ Get the full name of the parent folder of techcoil\r\nConsole.WriteLine(techcoilInfo.Parent.FullName);\r\n<\/pre>\n
Get list of files in a folder<\/h3>\n
\r\n\/\/ Get a list of pathnames of files that are in the techcoil folder.\r\nIEnumerable<string> filesInTechcoil = Directory.EnumerateFiles("techcoil");\r\n\r\n\/\/ Print the list of pathnames \r\nforeach (string filePath in filesInTechcoil) \r\n{\r\n    Console.WriteLine(filePath);\r\n} \/\/ end foreach\r\n<\/pre>\n
Get a list of folders in a folder<\/h3>\n
\r\n\/\/ Get the pathnames \r\nIEnumerable<string> foldersInTechcoil = Directory.EnumerateDirectories("techcoil");\r\nforeach (string folderPath in foldersInTechcoil)\r\n{\r\n    Console.WriteLine(folderPath);\r\n} \/\/ end foreach\r\n<\/pre>\n
