Visual c++ 无法将参数从字符[#]转换为LPWSTR 我在VisualC++中编译这个代码时，我得到了下面的错误。你能帮我解决这个问题吗 DWORD nBufferLength = MAX_PATH; char szCurrentDirectory[MAX_PATH + 1]; GetCurrentDirectory(nBufferLength, szCurrentDirectory); szCurrentDirectory[MAX_PATH +1 ] = '\0';

错误消息：

Error   5   error C2664: 'GetCurrentDirectoryW' : cannot convert parameter 2 from 'char [261]' to 'LPWSTR'  c:\car.cpp

似乎您已经定义了

UNICODE、\u UNICODE

编译器标志。在这种情况下，您需要将

szCurrentDirectory

的类型从

char

更改为

TCHAR

，您的程序被配置为编译为unicode。这就是为什么GetCurrentDirectory是GetCurrentDirectoryW，它需要一个

LPWSTR

（

wchar\u t*

）

GetCurrentDirectoryW需要

wchar\u t

而不是

char

数组。您可以使用

TCHAR

，它与GetCurrentDirectory一样，取决于unicode设置并始终表示适当的字符类型

不要忘了在

'\0'

前面加上

L

，以便使字符文字也成为unicode

标题：

#include <iostream>
#include <fstream>
#include <direct.h>
#include <string.h>
#include <windows.h> //not sure

std::string getCurrentDirectoryOnWindows()
{
    const unsigned long maxDir = 260;
    wchar_t currentDir[maxDir];
    GetCurrentDirectory(maxDir, currentDir);
    std::wstring ws(currentDir);
    std::string current_dir(ws.begin(), ws.end());
    return std::string(current_dir);
}

std::string path = getCurrentDirectoryOnWindows(); //Output like: C:\Users\NameUser\Documents\Programming\MFC Program 5

std::string FolderName = "NewFolder";
std::string Dir1 = getCurrentDirectoryOnWindows() + "\\" + FolderName;
_mkdir(Dir1.c_str());

调用函数：

#include <iostream>
#include <fstream>
#include <direct.h>
#include <string.h>
#include <windows.h> //not sure

std::string getCurrentDirectoryOnWindows()
{
    const unsigned long maxDir = 260;
    wchar_t currentDir[maxDir];
    GetCurrentDirectory(maxDir, currentDir);
    std::wstring ws(currentDir);
    std::string current_dir(ws.begin(), ws.end());
    return std::string(current_dir);
}

std::string path = getCurrentDirectoryOnWindows(); //Output like: C:\Users\NameUser\Documents\Programming\MFC Program 5

std::string FolderName = "NewFolder";
std::string Dir1 = getCurrentDirectoryOnWindows() + "\\" + FolderName;
_mkdir(Dir1.c_str());

在当前目录中创建目录（文件夹）：

#include <iostream>
#include <fstream>
#include <direct.h>
#include <string.h>
#include <windows.h> //not sure

std::string getCurrentDirectoryOnWindows()
{
    const unsigned long maxDir = 260;
    wchar_t currentDir[maxDir];
    GetCurrentDirectory(maxDir, currentDir);
    std::wstring ws(currentDir);
    std::string current_dir(ws.begin(), ws.end());
    return std::string(current_dir);
}

std::string path = getCurrentDirectoryOnWindows(); //Output like: C:\Users\NameUser\Documents\Programming\MFC Program 5

std::string FolderName = "NewFolder";
std::string Dir1 = getCurrentDirectoryOnWindows() + "\\" + FolderName;
_mkdir(Dir1.c_str());

这在MFC C++中是适用的。
