Summary<\/strong>: in this tutorial, you’ll learn how to create a directory in C# using the Directory.CreateDirectory<\/code>()<\/code> static method.<\/p>\n\n\n\n

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

The Directory.CreateDirectory<\/code>()<\/code> static method allows you to create a new directory. Here’s the syntax of the Directory.CreateDirectory()<\/code> method:<\/p>\n\n\n

public<\/span> static<\/span> DirectoryInfo CreateDirectory<\/span> (\n    string<\/span> path\n<\/span>)<\/span>;<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
In this syntax, the path<\/code> specifies the directory to create. <\/p>\n\n\n\n
The CreateDirectory()<\/code> static method creates a new directory and returns a DirectoryInfo<\/code> object that represents the directory of the specified path<\/code>.<\/p>\n\n\n\n
If the path to the directory exists, the CreateDirectory()<\/code> doesn’t<\/strong> throw an exception. Also, it returns a DirectoryInfo<\/code> object that represents the existing directory.<\/p>\n\n\n\n
The CreateDirectory()<\/code> static method raises an IOException<\/code> if the path<\/code> is a file, not a directory.<\/p>\n\n\n\n
If the path<\/code> contains subdirectories that do not exist, the CreateDirectory()<\/code> static method also creates corresponding subdirectories.<\/p>\n\n\n\n
For example, if you want to create a directory like C:\\backup\\2023\\03\\<\/code> and the C:\\backup<\/code> already exists, the CreateDirectory()<\/code> static method will create two directories:<\/p>\n\n\n\n
    \n
  • C:\\backup\\2023<\/code><\/li>\n\n\n\n
  • C:\\backup\\2023\\03<\/code><\/li>\n<\/ul>\n\n\n\n
    The CreateDirectory()<\/code> <\/code>method also allows you to create a directory on a remote computer to which the program has access. For example, you can create a directory to a shared folder like @\"\\\\shared\\reports\\sales\\\"<\/code>.<\/p>\n\n\n\n
    Using C# Directory.CreateDirectory() method to create new directories example<\/h2>\n\n\n\n
    The following program demonstrates how to use the Directory.CreateDirectory()<\/code><\/code> method to create a directory 2023<\/code> in the C:\\backup<\/code> directory and 12 subdirectories (from 00<\/code> to 12<\/code>) inside the directory 2023<\/code>:<\/p>\n\n\n
    using<\/span> static<\/span> System.Console;\n\nstring<\/span> dirname = @\"C:\\backup\\2023\"<\/span>;\n\nfor<\/span> (int<\/span> i = 1<\/span>; i <= 12<\/span>; i++)\n{\n    Directory.CreateDirectory(\n        Path.Combine(dirname, i.ToString(\"00\"<\/span>))\n    );\n}<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
    How it works.<\/p>\n\n\n\n
    First, declare a dirname<\/code> variable that stores the parent directory:<\/p>\n\n\n
    string<\/span> dirname = @\"C:\\backup\\2023\"<\/span>;<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
     Second, iterate over the number from 1 to 12 and create the subdirectories from 00<\/code> to 12<\/code>:<\/p>\n\n\n
    for<\/span> (int<\/span> i = 1<\/span>; i <= 12<\/span>; i++)\n{\n    Directory.CreateDirectory(\n        Path.Combine(dirname, i.ToString(\"00\"<\/span>))\n    );\n}<\/code><\/span>Code language:<\/span> C#<\/span> (<\/span>cs<\/span>)<\/span><\/small><\/pre>\n\n\n
    Note that we use the i.ToString(\"00\")<\/code> to pad a leading zero to a number like 01<\/code>, 02<\/code>, etc.<\/p>\n\n\n\n
    The program will create the directories structure like this:<\/p>\n\n\n
    c:\\backup\r\n\u2514\u2500\u2500 2023\r\n   \u251c\u2500\u2500 01\r\n   \u251c\u2500\u2500 02\r\n   \u251c\u2500\u2500 03\r\n   \u251c\u2500\u2500 04\r\n   \u251c\u2500\u2500 05\r\n   \u251c\u2500\u2500 06\r\n   \u251c\u2500\u2500 07\r\n   \u251c\u2500\u2500 08\r\n   \u251c\u2500\u2500 09\r\n   \u251c\u2500\u2500 10\r\n   \u251c\u2500\u2500 11\r\n   \u2514\u2500\u2500 12\r\n\r\ndirectory: 13<\/code><\/span>Code language:<\/span> plaintext<\/span> (<\/span>plaintext<\/span>)<\/span><\/small><\/pre>\n\n\n
