範例

以下範例檢查指定的目錄是否存在，若不存在則建立該目錄，並刪除該目錄。

using System;
using System.IO;

class Test
{
    public static void Main()
    {
        // Specify the directories you want to manipulate.
        DirectoryInfo di = new DirectoryInfo(@"c:\MyDir");

        try
        {
            // Determine whether the directory exists.
            if (di.Exists)
            {
                // Indicate that it already exists.
                Console.WriteLine("That path exists already.");
                return;
            }

            // Try to create the directory.
            di.Create();
            Console.WriteLine("The directory was created successfully.");

            // Delete the directory.
            di.Delete();
            Console.WriteLine("The directory was deleted successfully.");
        }
        catch (Exception e)
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
        finally {}
    }
}

open System.IO

// Specify the directories you want to manipulate.
let di = DirectoryInfo @"c:\MyDir"

try
    // Determine whether the directory exists.
    if di.Exists then
        // Indicate that it already exists.
        printfn "That path exists already."
    else
        // Try to create the directory.
        di.Create()
        printfn "The directory was created successfully."

        // Delete the directory.
        di.Delete()
        printfn "The directory was deleted successfully."
with e ->
    printfn $"The process failed: {e}"

Imports System.IO

Public Class Test

    Public Shared Sub Main()
        ' Specify the directories you want to manipulate.
        Dim di As DirectoryInfo = New DirectoryInfo("c:\MyDir")
        Try

            If di.Exists Then
                ' Indicate that it already exists.
                Console.WriteLine("That path exists already.")
                Return
            End If

            ' Try to create the directory.
            di.Create()
            Console.WriteLine("The directory was created successfully.")

            'Delete the directory.
            di.Delete()
            Console.WriteLine("The directory was deleted successfully.")

        Catch e As Exception
            Console.WriteLine("The process failed: {0}", e.ToString())
        End Try
    End Sub
End Class

備註

所有指定的 path 目錄都會被建立，除非其中 path 某些部分無效。 該 path 參數指定的是目錄路徑，而非檔案路徑。 如果目錄已經存在，這個方法就不會做任何事。 若在呼叫此方法前該目錄不存在，則在建立成功時，關於該目錄的任何快取屬性資訊都會被清除。

範例

以下程式碼範例在使用者的暫存資料夾中建立一個新目錄，並設定指定的目錄安全屬性：

using System.IO;
using System.Security.AccessControl;
using System.Security.Principal;
namespace ConsoleApp
{
    class Program
    {
        static void Main()
        {
            DirectorySecurity security = new DirectorySecurity();
            SecurityIdentifier identity = new SecurityIdentifier(WellKnownSidType.BuiltinUsersSid, null);
            FileSystemAccessRule accessRule = new FileSystemAccessRule(identity, FileSystemRights.FullControl, AccessControlType.Allow);
            security.AddAccessRule(accessRule);
            string path = Path.Combine(Path.GetTempPath(), "directoryToCreate");
            DirectoryInfo dirInfo = new DirectoryInfo(path);
            dirInfo.Create(security);
        }
    }
}

備註

利用此方法超載建立帶有存取控制的目錄，確保在安全措施生效前無法被存取。

如果目錄已經存在，這個方法就不會做任何事。
