Directory.GetCurrentDirectory 方法

定义

获取应用程序的当前工作目录。Gets the current working directory of the application.

public:
 static System::String ^ GetCurrentDirectory();
public static string GetCurrentDirectory ();
static member GetCurrentDirectory : unit -> string
Public Shared Function GetCurrentDirectory () As String

返回

String

一个字符串,该字符串包含当前工作目录的绝对路径且不以反斜杠 (\) 结尾。A string that contains the absolute path of the current working directory, and does not end with a backslash (\).

例外

调用方没有所要求的权限。The caller does not have the required permission.

此操作系统为 Windows CE,该系统不具有当前目录功能。The operating system is Windows CE, which does not have current directory functionality.

此方法在 .NET Compact Framework 中可用,但当前不支持。This method is available in the .NET Compact Framework, but is not currently supported.

示例

下面的示例演示如何使用 GetCurrentDirectory 方法。The following example demonstrates how to use the GetCurrentDirectory method.

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());
        }
    }
}
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())
        End Try
    End Sub
End Class

注解

当前目录不同于原始目录,该目录是启动进程的目录。The current directory is distinct from the original directory, which is the one from which the process was started.
