参数

返回

一个对象，表示指定路径处的目录。 无论指定路径上的目录是否已存在，都会返回此对象。

例外

示例

以下示例创建并删除指定的目录：

using System;
using System.IO;

class Test
{
    public static void Main()
    {
        // Specify the directory you want to manipulate.
        string path = @"c:\MyDir";
        
        // Determine whether the directory exists.
        if (Directory.Exists(path))
        {
            Console.WriteLine("That path exists already.");
            return;
        }
        
        DirectoryInfo di;
        try
        {
            // Try to create the directory.
            di = Directory.CreateDirectory(path);
            Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path));
        }
        catch (UnauthorizedAccessException e)
        {
            Console.WriteLine("The caller does not have the required permission to create `{0}`", path);
            return;
        }
        
        // Delete the directory.
        di.Delete();
        Console.WriteLine("The directory was deleted successfully.");
    }
}

open System.IO

// Specify the directory you want to manipulate.
let path = @"c:\MyDir"

try
    // Determine whether the directory exists.
    if Directory.Exists path then
        printfn "That path exists already."
    else
        // Try to create the directory.
        let di = Directory.CreateDirectory path
        printfn $"The directory was created successfully at {Directory.GetCreationTime path}."

        // 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 directory you want to manipulate.
        Dim path As String = "c:\MyDir"

        Try
            ' Determine whether the directory exists.
            If Directory.Exists(path) Then
                Console.WriteLine("That path exists already.")
                Return
            End If

            ' Try to create the directory.
            Dim di As DirectoryInfo = Directory.CreateDirectory(path)
            Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path))

            ' 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

若要在当前目录为 C：\Users\User1 时创建目录 C：\Users\User1\Public\Html，请使用以下任何调用来确保正确解释反斜杠：

Directory.CreateDirectory("Public\Html")
Directory.CreateDirectory("\Users\User1\Public\Html")
Directory.CreateDirectory("c:\Users\User1\Public\Html")

Directory.CreateDirectory("Public\\Html");
Directory.CreateDirectory("\\Users\\User1\\Public\\Html");
Directory.CreateDirectory("c:\\Users\\User1\\Public\\Html");

注解

创建任何 path 目录和所有目录，除非它们已存在，或者某些部分 path 无效。 如果目录已存在，此方法不会创建新目录，但它返回 DirectoryInfo 现有目录的对象。

该 path 参数指定目录路径，而不是文件路径。

在创建目录之前， path 将从参数末尾删除尾随空格。

可以在远程计算机上，在具有写入访问权限的共享上创建目录。 支持 UNC 路径;例如，可以为 path 指定以下内容：Visual Basic中的 \\2009\Archives\December，在 C# 中指定 \\\\2009\\Archives\\December。

创建仅包含冒号字符的目录（不支持:)，并将导致 NotSupportedException 引发。

在 Unix 系统上，使用正斜杠（/）作为路径分隔符。

示例

以下示例为两个用户帐户创建一个具有访问规则的新目录。

using System;
using System.IO;
using System.Security.AccessControl;

partial class Program
{
    static void DirectorySecurityExample()
    {
        DirectorySecurity securityRules = new DirectorySecurity();
        securityRules.AddAccessRule(new FileSystemAccessRule(@"Domain\account1", FileSystemRights.Read, AccessControlType.Allow));
        securityRules.AddAccessRule(new FileSystemAccessRule(@"Domain\account2", FileSystemRights.FullControl, AccessControlType.Allow));

        DirectoryInfo di = Directory.CreateDirectory(@"C:\destination\NewDirectory", securityRules);
    }
}

open System.IO
open System.Security.AccessControl

let securityRules = DirectorySecurity()
securityRules.AddAccessRule(FileSystemAccessRule(@"Domain\account1", FileSystemRights.Read, AccessControlType.Allow))
securityRules.AddAccessRule(FileSystemAccessRule(@"Domain\account2", FileSystemRights.FullControl, AccessControlType.Allow))

let di = Directory.CreateDirectory(@"C:\destination\NewDirectory", securityRules)

Imports System.IO
Imports System.Security.AccessControl

Partial Class Program
    Shared Sub DirectorySecurityExample()

        Dim securityRules As DirectorySecurity = New DirectorySecurity()
        securityRules.AddAccessRule(New FileSystemAccessRule("Domain\account1", FileSystemRights.Read, AccessControlType.Allow))
        securityRules.AddAccessRule(New FileSystemAccessRule("Domain\account2", FileSystemRights.FullControl, AccessControlType.Allow))

        Dim di As DirectoryInfo = Directory.CreateDirectory("C:\destination\NewDirectory", securityRules)

    End Sub
End Class

注解

使用此方法重载创建具有访问控制的目录，因此在应用安全性之前，无法访问目录。

将创建参数中指定的 path 任何目录和所有目录，除非它们已存在，或者除非部分 path 目录无效。 该 path 参数指定目录路径，而不是文件路径。 如果目录已存在，此方法不会创建新目录，但它返回 DirectoryInfo 现有目录的对象。

在创建目录之前， path 将从参数末尾删除尾随空格。

可以在远程计算机上，在具有写入访问权限的共享上创建目录。 支持 UNC 路径;例如，可以为 path 指定以下内容：Visual Basic中的 \\2009\Archives\December，在 C# 中指定 \\\\2009\\Archives\\December。

创建仅包含冒号字符的目录（不支持:)并导致 NotSupportedException 引发。
