Directory.GetCurrentDirectory 方法

定义

命名空间:

System.IO

程序集:

System.Runtime.dll

Source:

Directory.cs

获取应用程序的当前工作目录。

public:
 static System::String ^ GetCurrentDirectory();

public static string GetCurrentDirectory ();

static member GetCurrentDirectory : unit -> string

Public Shared Function GetCurrentDirectory () As String

返回

String

包含当前工作目录的绝对路径且不以反斜杠 (\) 结尾的字符串。

例外

UnauthorizedAccessException

调用方没有所要求的权限。

NotSupportedException

此操作系统为 Windows CE，该系统不具有当前目录功能。

此方法在 .NET Compact Framework 中可用，但当前不支持。

示例

下面的示例演示如何使用 GetCurrentDirectory 方法。

using namespace System;
using namespace System::IO;
int main()
{
   try
   {
      
      // Get the current directory.
      String^ path = Directory::GetCurrentDirectory();
      String^ target = "c:\\temp";
      Console::WriteLine( "The current directory is {0}", path );
      if (  !Directory::Exists( target ) )
      {
         Directory::CreateDirectory( target );
      }
      
      // Change the current directory.
      Environment::CurrentDirectory = target;
      if ( path->Equals( Directory::GetCurrentDirectory() ) )
      {
         Console::WriteLine( "You are in the temp directory." );
      }
      else
      {
         Console::WriteLine( "You are not in the temp directory." );
      }
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "The process failed: {0}", e );
   }

}

using System;
using System.IO;

class Test
{
    public static void Main()
    {
        try
        {
            // Get the current directory.
            string path = Directory.GetCurrentDirectory();
            string target = @"c:\temp";
            Console.WriteLine("The current directory is {0}", path);
            if (!Directory.Exists(target))
            {
                Directory.CreateDirectory(target);
            }

            // Change the current directory.
            Environment.CurrentDirectory = (target);
            if (path.Equals(Directory.GetCurrentDirectory()))
            {
                Console.WriteLine("You are in the temp directory.");
            }
            else
            {
                Console.WriteLine("You are not in the temp directory.");
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
    }
}

open System
open System.IO

try
    // Get the current directory.
    let path = Directory.GetCurrentDirectory()
    let target = @"c:\temp"
    printfn $"The current directory is {path}"
    if not (Directory.Exists target) then
        Directory.CreateDirectory target |> ignore

    // Change the current directory.
    Environment.CurrentDirectory <- target
    if path.Equals(Directory.GetCurrentDirectory()) then
        printfn "You are in the temp directory."
    else
        printfn "You are not in the temp directory."
with e ->
    printfn $"The process failed: {e}"

Imports System.IO

Public Class Test
    Public Shared Sub Main()
        Try
            ' Get the current directory.
            Dim path As String = Directory.GetCurrentDirectory()
            Dim target As String = "c:\temp"
            Console.WriteLine("The current directory is {0}", path)
            If Directory.Exists(target) = False Then
                Directory.CreateDirectory(target)
            End If
            ' Change the current directory.
            Environment.CurrentDirectory = (target)
            If path.Equals(Directory.GetCurrentDirectory()) Then
                Console.WriteLine("You are in the temp directory.")
            Else
                Console.WriteLine("You are not in the temp directory.")
            End If
        Catch e As Exception
            Console.WriteLine("The process failed: {0}", e.ToString())

注解

当前目录不同于原始目录，原始目录是从中启动进程的目录。
