获取应用程序的当前工作目录。

[Visual Basic]
Public Shared Function GetCurrentDirectory() As String

[C#]
public static string GetCurrentDirectory();

[C++]
public: static String* GetCurrentDirectory();

[JScript]
public static function GetCurrentDirectory() : String;

返回值

包含当前工作目录的路径的字符串。

异常

备注

当前目录不同于原始目录，后者是从其开始进程的目录。

有关使用此方法的示例，请参阅下面的“示例”部分。下表列出了其他典型或相关的 I/O 任务的示例。

示例

[Visual Basic, C#, C++] 下面的示例说明 GetCurrentDirectory 方法。

[Visual Basic] 
Imports System
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 path.Equals(Directory.GetCurrentDirectory()) Then
                Console.WriteLine("You are in the temp directory.")
            Else
                Console.WriteLine("You are not in the temp directory.")

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

        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
    }
}

[C++] 
#using <mscorlib.dll>

using namespace System;
using namespace System::IO;

void main() {
    try {
        // Get the current directory.
        String* path = Directory::GetCurrentDirectory();

        Console::WriteLine(S"The current directory is {0}", path);
        if (!Directory::Exists(target)) {
            Directory::CreateDirectory(target);
        }

        // Change the current directory.
        Environment::CurrentDirectory = target;
