Summary<\/strong>: in this tutorial, you’ll learn how to check if a directory exists using the Directory.Exists<\/code>()<\/code> static method.<\/p>\n\n\n\n

Introduction to the C# Directory.Exists() method<\/h2>\n\n\n\n

The Directory.Exists<\/code>()<\/code> method returns true<\/code> if a specified path to a directory exists or false<\/code> otherwise:<\/p>\n\n\n

public<\/span> static<\/span> bool<\/span> Exists<\/span> (string<\/span>? path<\/span>)<\/span>;<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
The path<\/code> can be relative or absolute. If you use a relative path, the Exists()<\/code> method interprets it as relative to the current working directory.<\/p>\n\n\n\n
The Exists()<\/code> method removes the trailing spaces from the path before checking.<\/p>\n\n\n\n
Note that the path is case-sensitive on Linux file systems but case-insensitive on Windows file systems.<\/p>\n\n\n\n
In practice, you use the Directory.Exists<\/code>()<\/code> method to check if a directory exists before carrying out other operations such as copying, moving, and deleting.<\/p>\n\n\n\n
C# Directory.Exist() method example<\/h2>\n\n\n\n
The following program demonstrates how to use the Directory.Exists<\/code>()<\/code> to check if the C:\\temp directory exists:<\/p>\n\n\n
using<\/span> static<\/span> System.Console;\n\nstring<\/span> dirname = @\"C:\\temp\\\"<\/span>;\n\nif<\/span> (Directory.Exists(dirname))\n{\n    WriteLine($\"The directory {dirname}<\/span> exists.\"<\/span>);\n}\nelse<\/span>\n{\n    WriteLine($\"The directory {dirname}<\/span> does not exist.\"<\/span>);\n}<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
The directory C:\\temp\\ exists.<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
