用c语言实现文件批量改名,检索,目录。不使用<dirent.h>

如果不使用 `dirent.h` 库,可以使用 `FindFirstFile` 和 `FindNextFile` 函数来遍历目录,以下是一个示例代码,可以列出指定目录下的所有文件和子目录:
```c
#include <stdio.h>
#include <windows.h>
void listFiles(const char *dirPath) {
HANDLE hFind;
WIN32_FIND_DATA findData;
char pattern[MAX_PATH];
snprintf(pattern, sizeof(pattern), "%s\\*", dirPath);
hFind = FindFirstFile(pattern, &findData);
if (hFind == INVALID_HANDLE_VALUE) {
printf("Failed to find %s\n", dirPath);
return;
}
do {
if (strcmp(findData.cFileName, ".") == 0 || strcmp(findData.cFileName, "..") == 0) {
continue;
}
if (findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
printf("Directory: %s\n", findData.cFileName);
char subDirPath[MAX_PATH];
snprintf(subDirPath, sizeof(subDirPath), "%s\\%s", dirPath, findData.cFileName);
listFiles(subDirPath);
} else {
printf("File: %s\n", findData.cFileName);
}
} while (FindNextFile(hFind, &findData));
FindClose(hFind);
}
int main() {
listFiles("C:\\example\\directory\\path");
return 0;
}
```
对于文件的批量改名和检索,可以使用 `FindFirstFile` 和 `FindNextFile` 函数遍历目录,找到需要改名或检索的文件,然后使用 `MoveFile` 函数进行重命名或移动操作。示例代码如下:
```c
#include <stdio.h>
#include <windows.h>
void renameFiles(const char *dirPath) {
HANDLE hFind;
WIN32_FIND_DATA findData;
char pattern[MAX_PATH];
snprintf(pattern, sizeof(pattern), "%s\\*.txt", dirPath);
hFind = FindFirstFile(pattern, &findData);
if (hFind == INVALID_HANDLE_VALUE) {
printf("Failed to find %s\n", dirPath);
return;
}
do {
if (strcmp(findData.cFileName, ".") == 0 || strcmp(findData.cFileName, "..") == 0) {
continue;
}
char oldPath[MAX_PATH], newPath[MAX_PATH];
snprintf(oldPath, sizeof(oldPath), "%s\\%s", dirPath, findData.cFileName);
snprintf(newPath, sizeof(newPath), "%s\\new_%s", dirPath, findData.cFileName);
MoveFile(oldPath, newPath);
} while (FindNextFile(hFind, &findData));
FindClose(hFind);
}
int main() {
renameFiles("C:\\example\\directory\\path");
return 0;
}
```
