定義

命名空間:

System.IO

組件:

System.Runtime.dll

來源:

Directory.cs

取得應用程式的目前工作目錄。

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

public static string GetCurrentDirectory ();

static member GetCurrentDirectory : unit -> string

Public Shared Function GetCurrentDirectory () As String

傳回

String

字串，其中包含目前工作目錄的絕對路徑，且結尾不會以反斜杠 (\) 結尾。

例外狀況

UnauthorizedAccessException

呼叫端沒有必要的權限。

NotSupportedException

作業系統是 Windows CE，它沒有當前的目錄功能。

.NET Compact Framework 提供方法，但目前不支援。

範例

下列範例示範如何使用 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);
            }
