我想在C,Windows中删除目录。我了解我必须首先删除目录中的所有文件,这是我很困惑的部分。我发现SHFileOperation
和IFileOperation
尽管从文档中不了解它们是如何实现的。
我当前的实现方式:
int dir_exists = 0;
snprintf(dir_name, STR_SIZE, "%s\\%s", LOCAL_DIR, tokens[1]);
// Check if directory exists
DWORD dwAttrib = GetFileAttributes(dir_name);
if (dwAttrib != INVALID_FILE_ATTRIBUTES && (dwAttrib & FILE_ATTRIBUTE_DIRECTORY)) {
dir_exists = 1;
}
if (dir_exists == 1) {
// Remove contents of directory (CURRENTLY UNIX)
DIR *dir;
struct dirent *d;
char filepath[FNAME_SIZE];
dir = opendir(dir_name);
while (d = readdir(dir)) {
sprintf(filepath, "%s/%s", dir_name, d->d_name);
remove(filepath);
}
// Remove directory
if ((RemoveDirectory(dir_name)) == 0) {
printf("Error removing dictionary\n");
return 0;
}
}
我想用Windows替换没有使用#include <dirent.h>
的部分,因为我的VS没有此头文件:
// Remove contents of directory (CURRENTLY UNIX)

解决方案功劳:Link
如解决方案所述,使用此功能时请小心,并确保将null终止pFrom
设为双倍。
dir_name[STR_SIZE];
int dir_exists = 0;
snprintf(dir_name, STR_SIZE, "folder/dir_to_be_deleted");
// Check if directory exists
DWORD dwAttrib = GetFileAttributes(dir_name);
if (dwAttrib != INVALID_FILE_ATTRIBUTES && (dwAttrib & FILE_ATTRIBUTE_DIRECTORY)) {
dir_exists = 1;
}
if (dir_exists == 1) {
// Remove contents of directory
snprintf(dir_name, STR_SIZE, "%s/%s", LOCAL_DIR, tokens[1]);
TCHAR szDir[MAX_PATH];
StringCchCopy(szDir, MAX_PATH, dir_name);
StringCchCat(szDir, MAX_PATH, TEXT("\\*"));
int len = _tcslen(szDir);
TCHAR* pszFrom = malloc((len + 4) * sizeof(TCHAR)); //4 to handle wide char
StringCchCopyN(pszFrom, len + 2, szDir, len + 2);
pszFrom[len] = 0;
pszFrom[len + 1] = 0;
SHFILEOPSTRUCT fileop;
fileop.hwnd = NULL; // no status display
fileop.wFunc = FO_DELETE; // delete operation
fileop.pFrom = pszFrom; // source file name as double null terminated string
fileop.pTo = NULL; // no destination needed
fileop.fFlags = FOF_NOCONFIRMATION | FOF_SILENT; // do not prompt the user
fileop.fAnyOperationsAborted = FALSE;
fileop.lpszProgressTitle = NULL;
fileop.hNameMappings = NULL;
if (SHFileOperation(&fileop) != 0) {
printf("Error SHFileOperation\n");
return 0;
}
free(pszFrom);
// Remove directory
if ((RemoveDirectory(dir_name)) == 0) {
printf("Error removing dictionary\n");
return 0;
}
}

这是一个列出文件夹中所有文件和目录的简单程序:
#include <stdio.h>
#include <dirent.h>
int main(void)
{
struct dirent *de; // Pointer for directory entry
// opendir() returns a pointer of DIR type.
DIR *dr = opendir(".");
if (dr == NULL) // opendir returns NULL if couldn't open directory
{
printf("Could not open current directory" );
return 0;
}
while ((de = readdir(dr)) != NULL)
printf("%s\n", de->d_name);
closedir(dr);
return 0;
}
它似乎没有您的代码复杂。 通过查看文件夹中每个条目的Dirent结构(是否为目录,是否为目录),应该很容易发现。然后将printf更改为某种文件的delete语句。
您可能需要调用stat才能告知文件或目录。

这是一个简单的Windows批处理文件,可以完成此工作。
@echo off
echo (batch file to remove a directory on windows)
cd /d %tmp%
for /d %%i in (*) do (echo this directory contains a folder "%%i") & (echo so it cannot be deleted) & (goto :END)
for /r %%i in (*) do (echo del %%i)
:END
更改第三行以使用您的目录。删除第5行上的“ echo”。 如果您被锁定使用“ c”,则可以使用“ system()”来运行它。
