-Example: Combine a path and a file name: +
-<code csharp> +
-string fullPath = Path.Combine(@"C:\Temp", "data.dbf"); +
-</code> +
- +
-Example: Show sections of a path. +
-<code csharp> +
-string path = @"C:\Temp\MyFolder\MyFile.txt"; +
-Console.WriteLine(Path.GetDirectoryName(path)); // C:\Temp\MyFolder +
-Console.WriteLine(Path.GetExtension(path));     // .txt +
-Console.WriteLine(Path.GetFileName(path));      // data.dbf +
-Console.WriteLine(Path.GetPathRoot(path));      // C:\ +
-</code> +

- +
-Example: Obtain random files and folders: +
-<code csharp> +
-// Obtain a random file name. +
-string name = Path.GetRandomFileName(); +
- +
-// Create a unique, temporary file in the user\AppData\Local\Temp folder and return the full path to that file. +
-string tmpFile = Path.GetTempFileName(); +
- +
-// Obtain the path of the current user's temporary folder. +
-string tmpFolder = Path.GetTempPath(); +

-You can use the //ZipArchive// and //ZipFile// classes to compress files in zip format. The classes are located in the //System.IO.Compression// namespace in the //System.IO.Compression.dll// assembly. This feature was introduced in .NET 4.5. +
- +
-Example: Zip all the files in a specified folder: +
-<code csharp> +
-ZipFile.CreateFromDirectory (@"C:\Documents", @"C:\Temp\docs.zip"); +
-</code> +
